DEPARTMENT OF NATURAL RESOURCES – DIVISION OF ECOLOGICAL AND
WATER RESOURCES AND METROPOLITAN COUNCIL
INTRODUCTION TO WATER SUPPLY PLANS (WSP)
Who needs to complete a Water Supply Plan
Public water suppliers serving more than 1,000 people, large private water suppliers in designated
Groundwater Management Areas, and all water suppliers in the Twin Cities metropolitan area are
required to prepare and submit a water supply plan.
The goal of the WSP is to help water suppliers: 1) implement long term water sustainability and
conservation measures; and 2) develop critical emergency preparedness measures. Your community
needs to know what measures will be implemented in case of a water crisis. A lot of emergencies can be
avoided or mitigated if long term sustainability measures are implemented.
Groundwater Management Areas (GWMA)
The DNR has designated three areas of the state as Groundwater Management Areas (GWMAs) to focus
groundwater management efforts in specific geographies where there is an added risk of overuse or
water quality degradation. A plan directing the DNRs actions within each GWMA has been prepared.
Although there are no specific additional requirements with respect to the water supply planning for
communities within designated GWMAs, communities should be aware of the issues and actions
planned if they are within the boundary of one of the GWMAs. The three GWMAs are the North and
East Metro GWMA (Twin Cities Metro), the Bonanza Valley GWMA and the Straight River GWMA (near
Park Rapids). Additional information and maps are included in the DNR webpage at
http://www.dnr.state.mn.us/gwmp/areas.html
Benefits of completing a WSP
Completing a WSP using this template, fulfills a water supplier’s statutory obligations under M.S.
M.S.103G.291 to complete a water supply plan. For water suppliers in the metropolitan area, the WSP
will help local governmental units to fulfill their requirements under M.S. 473.859 to complete a local
comprehensive plan. Additional benefits of completing WSP template:
The standardized format allows for quicker and easier review and approval.
Help water suppliers prepare for droughts and water emergencies.
Create eligibility for funding requests to the Minnesota Department of Health (MDH) for the
Drinking Water Revolving Fund.
Allow water suppliers to submit requests for new wells or expanded capacity of existing wells.
Simplify the development of county comprehensive water plans and watershed plans.
Fulfill the contingency plan provisions required in the MDH wellhead protection and surface
water protection plans.
Fulfill the demand reduction requirements of Minnesota Statutes, section 103G.291 subd 3
and 4.
Local Water Supply Plan Template –July 8, 2016

Upon implementation, contribute to maintaining aquifer levels, reducing potential well
interference and water use conflicts, and reducing the need to drill new wells or expand
system capacity.
Enable DNR to compile and analyze water use and conservation data to help guide decisions.
Conserve Minnesota’s water resources
If your community needs assistance completing the Water Supply Plan, assistance is available from your
area hydrologist or groundwater specialist, the MN Rural Waters Association circuit rider program, or in
the metropolitan area from Metropolitan Council staff. Many private consultants are also available.

Rosemount does not currently have a water treatment plant. Because Rosemount water quality meets all primary
drinking water standards, treatment is not mandated. Disinfection is accomplished by chlorination at the source
wells. Additional treatment includes fluoridation and polyphosphate at the source wells.

Treatment and storage capacity versus demand
It is recommended that total storage equal or exceed the average daily demand.
Discuss the difference between current storage and treatment capacity versus the water supplier’s
projected average water demand over the next 10 years (see Table 7 for projected water demand):
The City of Rosemount currently has 3,500,000 gallons of elevated storage between four steel elevated storage
tanks. Typically, it is desired to maintain a storage capacity greater than the average day demand (based on Ten
States Standards). In 2016, the average day demand is projected to be 2,495,664 gallons per day. Using the Ten
States Standards and comparing the average day demand to total storage capacity, there is a surplus of 1,004,336
gallons in 2016. Future projections over the next 10 years indicate the City of Rosemount will maintain a storage
capacity greater than the average day demand. In 2025, the City will have a projected average day demand of
3,027,572 gallons per day, yielding a storage surplus of 472,428 gallons. However, by 2030, a deficit in storage
volume of 360,626 gallons is projected. Therefore, additional storage is needed between 2025 and 2030.
The City of Rosemount does not operate any water treatment plants since the water quality meets all primary
drinking water standards. The City currently has a total well capacity of 10.1 MGD with a firm capacity (largest well
out of service) of 8.28 MGD. These well capacities are based on running the wells for 20 hours per day. It is common
practice to run the wells for only 20 hours per day maximum. Comparing future demands to current and future water
supplies is common for determining when and how many new sources of water are needed. Typically, the water
sources should have a firm capacity greater than the maximum day demand. From the future projections in Table 7,
it can be seen that in 2016 a maximum day demand of 7.24 MGD is predicted. This leads to a surplus of 1.04 MGD
of well water capacity using current firm well capacity. However, future projections indicate that by 2023 a deficit in
firm well capacity of 0.11 MGD (76 gpm) will occur, and additional wells will be required to meet the maximum day
demand of 8.39 MGD. There is not enough well capacity to supply the City of Rosemount for the next 10 years. T he
city will need to add an additional well(s) capable of producing at least 500 gpm by 2023 to have adequate water
supply for future demands.
C. Water Sources
Complete Table 6 by listing all types of water sources that supply water to the system, including
groundwater, surface water, interconnections with other water suppliers, or others. Provide the name
of each source (aquifer name, river or lake name, name of interconnecting water supplier) and the
Minnesota unique well number or intake ID, as appropriate. Report the year the source was installed or
established and the current capacity. Provide information about the depth of all wells. Describe the
status of the source (active, inactive, emergency only, retail/wholesale interconnection) and if the

source facilities have a dedicated emergency power source. Add rows to the table as needed for each
installation.
Include copies of well records and maintenance summary for each well that has occurred since your last
approved plan in Appendix 1.

Limits on Emergency Interconnections
Discuss any limitations on the use of the water sources (e.g. not to be operated simultaneously,
limitations due to blending, aquifer recovery issues etc.) and the use of interconnections, including
capacity limits or timing constraints (i.e. only 200 gallons per minute are available from the City of Prior
Lake, and it is estimated to take 6 hours to establish the emergency connection). If there are no
limitations, list none.
Interconnect available with the City of Apple Valley. The capacity o f the interconnect is 23,000 GPM.
D. Future Demand Projections – Key Metropolitan Council Benchmark
Water Use Trends
Use the data in Table 2 to describe trends in 1) population served; 2) total per capita water demand; 3)
average daily demand; 4) maximum daily demand. Then explain the causes for upward or downward
trends. For example, over the ten years has the average daily demand trended up or down? Why is this
occurring?
The historic trend in population served shows a consistent increase in the population served within the City of
Rosemount. Over the last ten years, the City saw an increase in the service population of 21.5%. The population
served over the last 10 years follows the expected trend. As the population served increased, the total number of
connections also increased.
Overall, the average total per capita water demand averaged 122 gallons per capita per day (gpcd). From Table 2, it
can be observed that the trend in total per capita demand has decreased over the last 10 years to 104 gpcd. There
are a few years with unusually high demands: such as 2007 where the demand was 142 gpcd and 2008 where the
Local Water Supply Plan Template –July 8, 2016
14
demand was 136 gpcd. The overall trend is a decreasing to tal per capita demand. This could be contributed to an
increasing population served with a decrease in total water pumped from wells. It appears that during wet years
(years with higher amounts of rain) the per capita demand decreases while dry years see an increase in total demand.
The average daily demand has averaged 2.41 over the last 10 years. This has remained consistent during the last 10
years of historical monitoring. There is no significant change in the average day demand. However, the City saw a
lower average demand during the last 5 years. This is due to less water being pumped from the wells.
The maximum day demand has also remained constant over the last 10 years. The historical data shows that the
maximum day demand averaged 6.1 MGD. There is no increasing or decreasing trend in the maximum day demand.
It is important to note that 2011 and 2013 saw an unusual occurrence in unaccounted for water. From Table 2 it can
be seen that there was 2.6% and 1% of all water was unaccounted for during these two years, respectively. This is
not typical as it means that there was more water sold than water pumped. Most likely, the total water pumped was
under estimated in these two years due to a malfunctioning data logger.
Use the water use trend information discussed above to complete Table 7 with projected annual
demand for the next ten years. Communities in the seven-county Twin Cities metropolitan area must
also include projections for 2030 and 2040 as part of their local comprehensive planning.
Projected demand should be consistent with trends evident in the historical data in Table 2, as discussed
above. Projected demand should also reflect state demographer population projections and/or other
planning projections.

Projection Method
Describe the method used to project water demand, including assumptions for population and business
growth and how water conservation and efficiency programs affect projected water demand:
Future populations were calculated using linear regression methods. The historic city and county population trends
were accounted for to project future populations. Therefore, the City future population follows a similar trend to
the County future population. Historically, the population served is approximately 91% of the total City population.
Future water Projections were based on future average and peak per capita demands. It was assumed that the
projected average per capita water demand would remain constant at 106 gallons per capita per day through 2040.
This is slightly larger than Ten States Standard’s typical water usage of 100 gallons per capita per day. Peak per capita
demand was assumed to be 307 gallons per capita per day, yielding a peaking factor (peak day to average day ratio)
of 2.90.

Potential Water Supply Issues & Natural Resource Impacts – Key DNR & Metropolitan Council
Benchmark
Complete Table 10 by listing the types of natural resources that are or could be impacted by permitted
water withdrawals. If known, provide the name of specific resources that may be impacted. Identify
what the greatest risks to the resource are and how the risks are being assessed. Identify any resource
protection thresholds – formal or informal – that have been established to identify when actions should
be taken to mitigate impacts. Provide information about the potential mitigation actions that may be
taken, if a resource protection threshold is crossed. Add additional rows to the table as needed. See
glossary at the end of the template for definitions.
Some of this baseline data should have been in your earlier water supply plans or county comprehensive
water plans. When filling out this table, think of what are the water supply risks, identify the resources,
determine the threshold and then determine what your community will do to mitigate the impacts.

Part 2. Emergency Preparedness Procedures
The emergency preparedness procedures outlined in this plan are intended to comply with the
contingency plan provisions required by MDH in the WHP and SWP. Water emergencies can occur as a
result of vandalism, sabotage, accidental contamination, mechanical problems, power failings, drought,
flooding, and other natural disasters. The purpose of emergency planning is to develop emergency
response procedures and to identify actions needed to improve emergency preparedness. In the case of
a municipality, these procedures should be in support of, and part of, an all-hazard emergency
operations plan. Municipalities that already have written procedures dealing with water emergencies
should review the following information and update existing procedures to address these water supply
protection measures.
A. Federal Emergency Response Plan
Section 1433(b) of the Safe Drinking Water Act, (Public Law 107-188, Title IV- Drinking Water Security
and Safety) requires community water suppliers serving over 3,300 people to prepare an Emergency
Response Plan.
Do you have a federal emergency response plan? Yes ☒ No ☐
If yes, what was the date it was certified? ___2007________

B. Operational Contingency Plan
All utilities should have a written operational contingency plan that describes measures to be taken for
water supply mainline breaks and other common system failures as well as routine maintenance.
Do you have a written operational contingency plan? Yes ☒ No ☐
At a minimum, a water supplier should prepare and maintain an emergency contact list of contractors
and suppliers.
C. Emergency Response Procedures
Water suppliers must meet the requirements of MN Rules 4720.5280 . Accordingly, the Minnesota
Department of Natural Resources (DNR) requires public water suppliers serving more than 1,000 people
to submit Emergency and Conservation Plans. Water emergency and conservation plans that have been
Local Water Supply Plan Template –July 8, 2016
26
approved by the DNR, under provisions of Minnesota Statute 186 and Minnesota Rules, part 6115.0770,
will be considered equivalent to an approved WHP contingency plan.
Emergency Telephone List
Prepare and attach a list of emergency contacts, including the MN Duty Officer (1-800-422-0798), as
Appendix 5. A template is available at www.mndnr.gov/watersupplyplans
The list should include key utility and community personnel, contacts in adjacent water suppliers, and
appropriate local, state and federal emergency contacts. Please be sure to verify and update the
contacts on the emergency telephone list and date it. Thereafter, update on a regular basis (once a year
is recommended). In the case of a municipality, this information should be contained in a notification
and warning standard operating procedure maintained by the Emergency Manager for that community.
Responsibilities and services for each contact should be defined.
Current Water Sources and Service Area
Quick access to concise and detailed information on water sources, water treatment, and the
distribution system may be needed in an emergency. System operation and maintenance records should
be maintained in secured central and back-up locations so that the records are accessible for emergency
purposes. A detailed map of the system showing the treatment plants, water sources, storage facilities,
supply lines, interconnections, and other information that would be useful in an emergency should also
be readily available. It is critical that public water supplier representatives and emergency response
personnel communicate about the response procedures and be able to easily obtain this kind of
information both in electronic and hard copy formats (in case of a power outage).
Do records and maps exist? Yes ☒ No ☐
Can staff access records and maps from a central secured location in the event of an emergency?
Yes ☒ No ☐
Does the appropriate staff know where the materials are located?
Yes ☒ No ☐
Procedure for Augmenting Water Supplies
Complete Tables 16 – 17 by listing all available sources of water that can be used to augment or replace
existing sources in an emergency. Add rows to the tables as needed.
In the case of a municipality, this information should be contained in a notification and warning
standard operating procedure maintained by the warning point for that community. Municipalities are
encouraged to execute cooperative agreements for potential emergency water services and copies
should be included in Appendix 6. Outstate Communities may consider using nearby high capacity wells
(industry, golf course) as emergency water sources.
Local Water Supply Plan Template –July 8, 2016

WSP should include information on any physical or chemical problems that may limit interconnections
to other sources of water. Approvals from the MDH are required for interconnections or the reuse of
water.

Allocation and Demand Reduction Procedures
Complete Table 18 by adding information about how decisions will be made to allocate water and
reduce demand during an emergency. Provide information for each customer category, including its
priority ranking, average day demand, and demand reduction potential for each customer category.
Modify the customer categories as needed, and add additional lines if necessary.
Water use categories should be prioritized in a way that is consistent with Minnesota Statutes 103G.261
(#1 is highest priority) as follows:
1. Water use for human needs such as cooking, cleaning, drinking, washing and waste disposal; use
for on-farm livestock watering; and use for power production that meets contingency
requirements.
2. Water use involving consumption of less than 10,000 gallons per day (usually from private wells
or surface water intakes)
3. Water use for agricultural irrigation and processing of agricultural products involving
consumption of more than 10,000 gallons per day (usually from private high-capacity wells or
surface water intakes)
4. Water use for power production above the use provided for in the contingency plan.
Local Water Supply Plan Template –July 8, 2016
28
5. All other water use involving consumption of more than 10,000 gallons per day.
6. Nonessential uses – car washes, golf courses, etc.
Water used for human needs at hospitals, nursing homes and similar types of facilities should be
designated as a high priority to be maintained in an emergency. Lower priority uses will need to address
water used for human needs at other types of facilities such as hotels, office buildings, and
manufacturing plants. The volume of water and other types of water uses at these facilities must be
carefully considered. After reviewing the data, common sense should dictate local allocation priorities to
protect domestic requirements over certain types of economic needs. Water use for lawn sprinkling,
vehicle washing, golf courses, and recreation are legislatively considered non-essential.

TOTAL NA 2,360,000 280,000
GPD – Gallons per Day
Tip: Calculating Emergency Demand Reduction Potential
The emergency demand reduction potential for all uses will typically equal the difference between
maximum use (summer demand) and base use (winter demand). In extreme emergency situations,
lower priority water uses must be restricted or eliminated to protect priority domestic water
requirements. Emergency demand reduction potential should be based on average day demands for
customer categories within each priority class. Use the tables in Part 3 on water conservation to help
you determine strategies.

Enforcement
Prior to a water emergency, municipal water suppliers must adopt regulations that restrict water use
and outline the enforcement response plan. The enforcement response plan must outline how
conditions will be monitored to know when enforcement actions are triggered, what enforcement tools
will be used, who will be responsible for enforcement, and what timelines for corrective actions will be
expected.
Affected operations, communications, and enforcement staff must then be trained to rapidly implement
those provisions during emergency conditions.
Important Note:
Disregard of critical water deficiency orders, even though total appropriation remains less than
permitted, is adequate grounds for immediate modification of a public water supply authority’s water
use permit (2013 MN Statutes 103G.291)
Does the city have a critical water deficiency restriction/official control in place that includes
provisions to restrict water use and enforce the restrictions? (This restriction may be an ordinance,
rule, regulation, policy under a council directive, or other official control) Yes ☒ No ☐
If yes, attach the official control document to this WSP as Appendix 7.
If no, the municipality must adopt such an official control within 6 months of submitting this WSP and
submit it to the DNR as an amendment to this WSP.
Irrespective of whether a critical water deficiency control is in place, does the public water supply
utility, city manager, mayor, or emergency manager have standing authority to implement water
restrictions? Yes ☒ No ☐
If yes, cite the regulatory authority reference: City Council or Utility Board, and City Administrator.
If no, who has authority to implement water use restrictions in an emergency?
Local Water Supply Plan Template –July 8, 2016

The City of Rosemount’s Emergency Operation Plan states that the Mayor or City Administrator is responsible for
providing overall direction and control of the City government resources involved in the response to a disaster.
Typically, the Utilities Commission and City Council implement water restrictions.

PART 3. WATER CONSERVATION PLAN
Minnesotans have historically benefited from the state’s abundant
water supplies, reducing the need for conservation. There are
however, limits to the available supplies of water and increasing
threats to the quality of our drinking water. Causes of water supply
limitation may include: population increases, economic trends,
uneven statewide availability of groundwater, climatic changes, and
degraded water quality. Examples of threats to drinking water
quality include: the presence of contaminant plumes from past land
use activities, exceedances of water quality standards from natural
and human sources, contaminants of emerging concern, and
increasing pollutant trends from nonpoint sources.
There are many incentives for conserving water; conservation:
reduces the potential for pumping-induced transfer of contaminants into the deeper aquifers,
which can add treatment costs
reduces the need for capital projects to expand system capacity
reduces the likelihood of water use conflicts, like well interference, aquatic habitat loss, and
declining lake levels
conserves energy, because less energy is needed to extract, treat and distribute water (and less
energy production also conserves water since water is use to produce energy)
maintains water supplies that can then be available during times of drought
It is therefore imperative that water suppliers implement water conservation plans. The first step in
water conservation is identifying opportunities for behavioral or engineering changes that could be
made to reduce water use by conducting a thorough analysis of:
Water use by customer
Extraction, treatment, distribution and irrigation system efficiencies
Industrial processing system efficiencies
Regulatory and barriers to conservation
Cultural barriers to conservation
Water reuse opportunities
Once accurate data is compiled, water suppliers can set achievable goals for reducing water use. A
successful water conservation plan follows a logical sequence of events. The plan should address both
conservation on the supply side (leak detection and repairs, metering), as well as on the demand side
(reductions in usage). Implementation should be conducted in phases, starting with the most obvious
and lowest-cost options. In some cases one of the early steps will be reviewing regulatory constraints to
water conservation, such as lawn irrigation requirements. Outside funding and grants may be available
for implementation of projects. Engage water system operators and maintenance staff and customers
in brainstorming opportunities to reduce water use. Ask the question: “How can I help save water?”

B. Conservation Objectives and Strategies – Key benchmark for DNR
This section establishes water conservation objectives and strategies for eight major areas of water use.
Objective 1: Reduce Unaccounted (Non-Revenue) Water loss to Less than 10%
The Minnesota Rural Waters Association, the Metropolitan Council and the Department of Natural
Resources recommend that all water uses be metered. Metering can help identify high use locations
and times, along with leaks within buildings that have multiple meters.
It is difficult to quantify specific unmetered water use such as that associated with firefighting and
system flushing or system leaks. Typically, water suppliers subtract metered water use from total water
pumped to calculate unaccounted or non-revenue water loss.
Is your five-year average (2005-2014) unaccounted Water Use in Table 2 higher than 10%?
Yes ☐ No ☒
Local Water Supply Plan Template –July 8, 2016
35
What is your leak detection monitoring schedule? (e.g. monitor 1/3rd of the city lines per year)
Leak detection is done as needed during the year.
Water Audits - are intended to identify, quantify and verify water and revenue losses. The volume of
unaccounted-for water should be evaluated each billing cycle. The American Water Works Association
(AWWA) recommends that ten percent or less of pumped water is unaccounted-for water. Water audit
procedures are available from the AWWA and MN Rural Water Association / . Drinking Water Revolving
Loan Funds are available for purchase of new meters when new plants are built.
What is the date of your most recent water audit? _______
Frequency of water audits: ☐ yearly ☒ other (specify frequency) _No Schedule_______
Leak detection and survey: ☐ every year ☐ every other year ☒ periodic as needed
Year last leak detection survey completed: The City of Rosemount does not have a citywide leak
detection survey. However, a leak detection survey is performed as part of street paving projects.
If Table 2 shows annual water losses over 10% or an increasing trend over time, describe what actions
will be taken to reach the <10% loss objective and within what timeframe
There is a less than 10% loss for each year over the last 10 years. The year 2006 has the only loss greater
than 10%.
Metering -AWWA recommends that every water supplier install meters to account for all water taken
into its system, along with all water distributed from its system at each customer’s point of service. An
effective metering program relies upon periodic performance testing, repair, maintenance or
replacement of all meters. AWWA also recommends that water suppliers conduct regular water audits
to ensure accountability. Some cities install separate meters for interior and exterior water use, but
some research suggests that this may not result in water conservation.
Complete Table 23 by adding the requested information regarding the number, types, testing and
maintenance of customer meters.

Objective 2: Achieve Less than 75 Residential Gallons per Capita Demand (GPCD)
The 2002 average residential per capita demand in the Twin Cities Metropolitan area was 75 gallons per
capita per day.
Is your average 2010-2015 residential per capita water demand in Table 2 more than 75? Yes ☒ No ☐
What was your 2010 – 2015 five-year average residential per capita water demand? 81.2 g/person/day
Describe the water use trend over that timeframe:
The residential water demand has been decreasing since 2008 where the peak demand of 115 gallons per capita
per day (gpcd) occurred. The residential per capita demand in 2015 was 70.1 gpcd. The overall residential water
sold has also declined during this period, which corresponds to the decreasing water demand.
Complete Table 25 by checking which strategies you will use to continue reducing residential per capita
demand and project a likely timeframe for completing each checked strategy (Select all that apply and
add rows for additional strategies):

☐ Provide rebates or incentives to reduce outdoor water use
(e.g., turf replacement/reduction, rain gardens, rain barrels,
smart irrigation, outdoor water use meters, etc.)
☐ Identify supplemental Water Resources
☐ Conduct audience-appropriate water conservation education
and outreach.
☐ Describe other plans
Objective 3: Achieve at least a 1.5% per year water reduction for Institutional, Industrial,
Commercial, and Agricultural GPCD over the next 10 years or a 15% reduction in ten years.
Complete Table 26 by checking which strategies you will used to continue reducing non-residential
customer use demand and project a likely timeframe for completing each checked strategy (add rows
for additional strategies).
Where possible, substitute recycled water used in one process for reuse in another. (For example, spent
rinse water can often be reused in a cooling tower.) Keep in mind the true cost of water is the amount
on the water bill PLUS the expenses to heat, cool, treat, pump, and dispose of/discharge the water.
Don’t just calculate the initial investment. Many conservation retrofits that appear to be prohibitively
expensive are actually very cost-effective when amortized over the life of the equipment. Often
reducing water use also saves electrical and other utility costs. Note: as of 2015, water reuse, and is not
allowed by the state plumbing code, M.R. 4715 (a variance is needed). However several state agencies
are addressing this issue.

☐ Describe other plans:
Objective 4: Achieve a Decreasing Trend in Total Per Capita Demand
Include as Appendix 8 one graph showing total per capita water demand for each customer category
(i.e., residential, institutional, commercial, industrial) from 2005-2014 and add the calculated/estimated
linear trend for the next 10 years.
Describe the trend for each customer category; explain the reason(s) for the trends, and where trends
are increasing.
The overall trend for total water demand has been decreasing for the last 10 years. The projected 10-
year linear trend also shows a decreasing total demand trend. The reason for the decreasing trend is
due to lower water usage and a decrease in the amount of residential and water used for non-essential
purposes. This, paired with a moderate increase in population served has led to the decreasing trend of
total demand.
The residential demand also follows a decreasing trend. However, there are three years where the
demand was greater than 100 gpcd. The 10-year linear trend shows a residential demand that continues
to decrease. The moderate increase in population served coupled along with a decrease in the
residential water sold leads to the decreasing residential demand.
The C/I/I demand has remained consistent but shows a slight decline over the last 10 years. The future
linear trend shows the C/I/I demand to slightly decrease. There are slight fluctuations in the demand
data where years with higher total demands correspond to higher C/I/I demands. This could be due to
larger than average water usage in the commercial/industrial/institutional category.
Objective 5: Reduce Peak Day Demand so that the Ratio of Average Maximum day to the
Average Day is less than 2.6
Is the ratio of average 2005-2014 maximum day demand to average 2005-2014 average day demand
reported in Table 2 more than 2.6? Yes ☒ No ☐
Local Water Supply Plan Template –July 8, 2016
39
Calculate a ten year average (2005 – 2014) of the ratio of maximum day demand to average day
demand: 2.53
The position of the DNR has been that a peak day/average day ratio that is above 2.6 for in summer
indicates that the water being used for irrigation by the residents in a community is too large and that
efforts should be made to reduce the peak day use by the community.
It should be noted that by reducing the peak day use, communities can also reduce the amount of
infrastructure that is required to meet the peak day use. This infrastructure includes new wells, new
water towers which can be costly items.
Objective 6: Implement a Conservation Water Rate Structure and/or a Uniform Rate
Structure with a Water Conservation Program
Water Conservation Program
Municipal water suppliers serving over 1,000 people are required to adopt demand reduction measures
that include a conservation rate structure, or a uniform rate structure with a conservation program that
achieves demand reduction. These measures must achieve demand reduction in ways that reduce
water demand, water losses, peak water demands, and nonessential water uses. These measures must
be approved before a community may request well construction approval from the Department of
Health or before requesting an increase in water appropriations permit volume (Minnesota Statutes,
section 103G.291, subd. 3 and 4). Rates should be adjusted on a regular basis to ensure that revenue of
the system is adequate under reduced demand scenarios. If a municipal water supplier intends to use a
Uniform Rate Structure, a community-wide Water Conservation Program that will achieve demand
reduction must be provided.
Current Water Rates
Include a copy of the actual rate structure in Appendix 9 or list current water rates including
base/service fees and volume charges below.

* Rate Structures components that may promote water conservation:
Monthly billing: is encouraged to help people see their water usage so they can consider changing
behavior.
Increasing block rates (also known as a tiered residential rate structure): Typically, these have at least
three tiers: should have at least three tiers.
o The first tier is for the winter average water use.
o The second tier is the year-round average use, which is lower than typical summer use. This rate
should be set to cover the full cost of service.
o The third tier should be above the average annual use and should be priced high enough to
encourage conservation, as should any higher tiers. For this to be effective, the difference in
block rates should be significant.
Seasonal rate: higher rates in summer to reduce peak demands
Time of Use rates: lower rates for off peak water use
Bill water use in gallons: this allows customers to compare their use to average rates
Individualized goal rates: typically used for industry, business or other large water users to promote
water conservation if they keep within agreed upon goals. Excess Use rates: if water use goes above an
agreed upon amount this higher rate is charged
Drought surcharge: an extra fee is charged for guaranteed water use during drought
Use water bill to provide comparisons: simple graphics comparing individual use over time or compare
individual use to others.
Local Water Supply Plan Template –July 8, 2016
41
Service charge or base fee that does not include a water volume – a base charge or fee to cover universal
city expenses that are not customer dependent and/or to provide mi nimal water at a lower rate (e.g., an
amount less than the average residential per capita demand for the water supplier for the last 5 years)
Emergency rates -A community may have a separate conservation rate that only goes into effect when
the community or governor declares a drought emergency. These higher rates can help to protect the city
budgets during times of significantly less water usage.
**Conservation Neutral**
Uniform rate: rate per unit used is the same regardless of the volume used
Odd/even day watering –This approach reduces peak demand on a daily basis for system operation, but
it does not reduce overall water use.
*** Non-Conserving ***
Service charge or base fee with water volume: an amount of water larger than the average residential
per capita demand for the water supplier for the last 5 years
Declining block rate: the rate per unit used decreases as water use increases.
Flat rate: one fee regardless of how much water is used (usually unmetered).
Provide justification for any conservation neutral or non-conserving rate structures. If intending to adopt
a conservation rate structure, include the timeframe to do so:
Objective 7: Additional strategies to Reduce Water Use and Support Wellhead Protection
Planning
Development and redevelopment projects can provide additional water conservation opportunities,
such as the actions listed below. If a Uniform Rate Structure is in place, the water supplier must provide
a Water Conservation Program that includes at least two of the actions listed below. Check those actions
that you intent to implement within the next 10 years.
Table 28. Additional strategies to Reduce Water Use & Support Wellhead Protection
☐ Participate in the GreenStep Cities Program, including implementation of at least one of the 20
“Best Practices” for water
☐ Prepare a master plan for smart growth (compact urban growth that avoids sprawl)
☐ Prepare a comprehensive open space plan (areas for parks, green spaces, natural areas)
☐ Adopt a water use restriction ordinance (lawn irrigation, car washing, pools, etc.)
☐ Adopt an outdoor lawn irrigation ordinance
☐ Adopt a private well ordinance (private wells in a city must comply with water restrictions)
☐ Implement a stormwater management program
☐ Adopt non-zoning wetlands ordinance (can further protect wetlands beyond state/federal laws-
for vernal pools, buffer areas, restrictions on filling or alterations)
☐ Adopt a water offset program (primarily for new development or expansion)
☐ Implement a water conservation outreach program
☐ Hire a water conservation coordinator (part-time)
☐ Implement a rebate program for water efficient appliances, fixtures, or outdoor water
management
☐ Other
Local Water Supply Plan Template –July 8, 2016
42
Objective 8: Tracking Success: How will you track or measure success through the next ten
years?
Tip: The process to monitor demand reduction and/or a rate structure includes:
a) The DNR Hydrologist will call or visit the community the first 1-3 years after the water supply plan is
completed.
b) They will discuss what activities the community is doing to conserve water and if they feel their
actions are successful. The Water Supply Plan, Part 3 tables and responses will guide the discussion.
For example, they will discuss efforts to reduce unaccounted for water loss if that is a problem, or go
through Tables 33, 34 and 35 to discuss new initiatives.
c) The city representative and the hydrologist will discuss total per capita water use, residential per
capita water use, and business/industry use. They will note trends.
d) They will also discuss options for improvement and/or collect case studies of success stories to share
with other communities. One option may be to change the rate structure, but there are many other
paths to successful water conservation.
e) If appropriate, they will cooperatively develop a simple work plan for the next few years, targeting a
couple areas where the city might focus efforts.

B. Retrofitting Programs
Education and incentive programs aimed at replacing inefficient plumbing fixtures and appliances can
help reduce per capita water use, as well as energy costs. It is recommended that municipal water
suppliers develop a long-term plan to retrofit public buildings with water efficient plumbing fixtures and
appliances. Some water suppliers have developed partnerships with organizations having similar
conservation goals, such as electric or gas suppliers, to develop cooperative rebate and retrofit
programs.
A study by the AWWA Research Foundation (Residential End Uses of Water, 1999) found that the
average indoor water use for a non-conserving home is 69.3 gallons per capita per day (gpcd). The
average indoor water use in a conserving home is 45.2 gpcd and most of the decrease in water use is
related to water efficient plumbing fixtures and appliances that can reduce water, sewer and energy
costs. In Minnesota, certain electric and gas providers are required (Minnesota Statute 216B.241) to
fund programs that will conserve energy resources and some utilities have distributed water efficient
showerheads to customers to help reduce energy demands required to supply hot water.

provided information on how to conserve water and improve water use efficiencies. Second,
information should be provided at appropriate times to address peak demands. Third, emergency
notices and educational materials about how to reduce water use should be available for quick
distribution during an emergency.

Part 4. ITEMS FOR METROPOLITAN AREA COMMUNITIES
Minnesota Statute 473.859 requires WSPs to be completed for all local units of
government in the seven-county Metropolitan Area as part of the local
comprehensive planning process.
Much of the information in Parts 1-3 addresses water demand for the next 10 years. However,
additional information is needed to address water demand through 2040, which will make the WSP
consistent with the Metropolitan Land Use Planning Act, upon which the local comprehensive plans are
based.
This Part 4 provides guidance to complete the WSP in a way that addresses plans for water supply
through 2040.
A. Water Demand Projections through 2040
Complete Table 7 in Part 1D by filling in information about long-term water demand projections through
2040. Total Community Population projections should be consistent with the community’s system
statement, which can be found on the Metropolitan Council’s website and which was sent to the
community in September 2015.
Projected Average Day, Maximum Day, and Annual Water Demands may either be calculated using the
method outlined in Appendix 2 of the 2015 Master Water Supply Plan or by a method developed by the
individual water supplier.
B. Potential Water Supply Issues
Complete Table 10 in Part 1E by providing information about the potential water supply issues in your
community, including those that might occur due to 2040 projected water use.
The Master Water Supply Plan provides information about potential issues for your community in
Appendix 1 (Water Supply Profiles). This resource may be useful in completing Table 10.
You may document results of local work done to evaluate impact of planned uses by attaching a
feasibility assessment or providing a citation and link to where the plan is available electronically.
C. Proposed Alternative Approaches to Meet Extended Water Demand
Projections
Complete Table 12 in Part 1F with information about potential water supply infrastructure impacts (such
as replacements, expansions or additions to wells/intakes, water storage and treatment capacity,
distribution systems, and emergency interconnections) of extended plans for development and
redevelopment, in 10-year increments through 2040. It may be useful to refer to information in the
community’s local Land Use Plan, if available.
Complete Table 14 in Part 1F by checking each approach your community is considering to meet future
demand. For each approach your community is considering, provide information about the amount of
Local Water Supply Plan Template –July 8, 2016
49
future water demand to be met using that approach, the timeframe to implement the approach,
potential partners, and current understanding of the key benefits and challenges of the approach.
As challenges are being discussed, consider the need for: evaluation of geologic conditions (mapping,
aquifer tests, modeling), identification of areas where domestic wells could be impacted, measurement
and analysis of water levels & pumping rates, triggers & associated actions to protect water levels, etc.
D. Value-Added Water Supply Planning Efforts (Optional)
The following information is not required to be completed as part of the local water supply plan, but
completing this can help strengthen source water protection throughout the region and help
Metropolitan Council and partners in the region to better support local efforts.
Source Water Protection Strategies
Does a Drinking Water Supply Management Area for a neighboring public water supplier overlap your
community? Yes ☐ No ☐
If you answered no, skip this section. If you answered yes, please complete Table 32 with information
about new water demand or land use planning-related local controls that are being considered to
provide additional protection in this area.

Local Control Schedule to
Implement
Potential Partners
☐ None at this time
☐ Comprehensive planning that guides development in
vulnerable drinking water supply management areas
☐ Zoning overlay
☐ Other:
Technical assistance
From your community’s perspective, what are the most important topics for the Metropolitan Council to
address, guided by the region’s Metropolitan Area Water Supply Advisory Committee and Technical
Advisory Committee, as part of its ongoing water supply planning role?
☒ Coordination of state, regional and local water supply planning roles
☐ Regional water use goals
☒ Water use reporting standards
☐ Regional and sub-regional partnership opportunities
☐ Identifying and prioritizing data gaps and input for regional and sub-regional analyses
☐ Others: ___________________________________________________________________

GLOSSARY
Agricultural/Irrigation Water Use - Water used for crop and non-crop irrigation, livestock watering,
chemigation, golf course irrigation, landscape and athletic field irrigation.
Average Daily Demand - The total water pumped during the year divided by 365 days.
Calcareous Fen - Calcareous fens are rare and distinctive wetlands dependent on a constant supply of
cold groundwater. Because they are dependent on groundwater and are one of the rarest natural
communities in the United States, they are a protected resource in MN. Approximately 200 have been
located in Minnesota. They may not be filled, drained or otherwise degraded.
Commercial/Institutional Water Use - Water used by motels, hotels, restaurants, office buildings,
commercial facilities and institutions (both civilian and military). Consider maintaining separate
institutional water use records for emergency planning and allocation purposes. Water used by multi-
family dwellings, apartment buildings, senior housing complexes, and mobile home parks should be
reported as Residential Water Use.
Commercial/Institutional/Industrial (C/I/I) Water Sold - The sum of water delivered for
commercial/institutional or industrial purposes.
Conservation Rate Structure - A rate structure that encourages conservation and may include increasing
block rates, seasonal rates, time of use rates, individualized goal rates, or excess use rates. If a
conservation rate is applied to multifamily dwellings, the rate structure must consider each residential
unit as an individual user. A community may have a separate conservation rate that only goes into
effect when the community or governor declares a drought emergency. These higher rates can help to
protect the city budgets during times of significantly less water usage.
Date of Maximum Daily Demand - The date of the maximum (highest) water demand. Typically this is a
day in July or August.
Declining Rate Structure - Under a declining block rate structure, a consumer pays less per additional
unit of water as usage increases. This rate structure does not promote water conservation.
Distribution System - Water distribution systems consist of an interconnected series of pipes, valves,
storage facilities (water tanks, water towers, reservoirs), water purification facilities, pumping stations,
flushing hydrants, and components that convey drinking water and meeting fire protection needs for
cities, homes, schools, hospitals, businesses, industries and other facilities.
Flat Rate Structure - Flat fee rates do not vary by customer characteristics or water usage. This rate
structure does not promote water conservation.
Industrial Water Use - Water used for thermonuclear power (electric utility generation) and other
industrial use such as steel, chemical and allied products, paper and allied products, mining, and
petroleum refining.

51
Low Flow Fixtures/Appliances - Plumbing fixtures and appliances that significantly reduce the amount
of water released per use are labeled “low flow”. These fixtures and appliances use just enough water to
be effective, saving excess, clean drinking water that usually goes down the drain.
Maximum Daily Demand - The maximum (highest) amount of water used in one day.
Metered Residential Connections - The number of residential connections to the water system that
have meters. For multifamily dwellings, report each residential unit as an individual user.
Percent Unmetered/Unaccounted For - Unaccounted for water use is the volume of water withdrawn
from all sources minus the volume of water delivered. This value represents water “lost” by
miscalculated water use due to inaccurate meters, water lost through leaks, or water that is used but
unmetered or otherwise undocumented. Water used for public services such as hydrant flushing, ice
skating rinks, and public swimming pools should be reported under the category “Water Supplier
Services”.
Population Served - The number of people who are served by the community’s public water supply
system. This includes the number of people in the community who are connected to the public water
supply system, as well as people in neighboring communities who use water supplied by the
community’s public water supply system. It should not include residents in the community who have
private wells or get their water from neighboring water supply.
Residential Connections - The total number of residential connections to the water system. For
multifamily dwellings, report each residential unit as an individual user.
Residential Per Capita Demand - The total residential water delivered during the year divided by the
population served divided by 365 days.
Residential Water Use - Water used for normal household purposes such as drinking, food preparation,
bathing, washing clothes and dishes, flushing toilets, and watering lawns and gardens. Should include all
water delivered to single family private residences, multi-family dwellings, apartment buildings, senior
housing complexes, mobile home parks, etc.
Smart Meter - Smart meters can be used by municipalities or by individual homeowners. Smart
metering generally indicates the presence of one or more of the following:
Smart irrigation water meters are controllers that look at factors such as weather, soil, slope,
etc. and adjust watering time up or down based on data. Smart controllers in a typical summer
will reduce water use by 30%-50%. Just changing the spray nozzle to new efficient models can
reduce water use by 40%.
Smart Meters on customer premises that measure consumption during specific time periods and
communicate it to the utility, often on a daily basis.
A communication channel that permits the utility, at a minimum, to obtain meter reads on
demand, to ascertain whether water has recently been flowing through the meter and onto the
Local Water Supply Plan Template –July 8, 2016
52
premises, and to issue commands to the meter to perform specific tasks such as disconnecting
or restricting water flow.
Total Connections - The number of connections to the public water supply system.
Total Per Capita Demand - The total amount of water withdrawn from all water supply sources during
the year divided by the population served divided by 365 days.
Total Water Pumped - The cumulative amount of water withdrawn from all water supply sources during
the year.
Total Water Delivered - The sum of residential, commercial, industrial, institutional, water supplier
services, wholesale and other water delivered.
Ultimate (Full Build-Out) - Time period representing the community’s estimated total amount and
location of potential development, or when the community is fully built out at the final planned density.
Unaccounted (Non-revenue) Loss - See definitions for “percent unmetered/unaccounted for loss”.
Uniform Rate Structure - A uniform rate structure charges the same price-per-unit for water usage
beyond the fixed customer charge, which covers some fixed costs. The rate sends a price signal to the
customer because the water bill will vary by usage. Uniform rates by class charge the same price-per-
unit for all customers within a customer class (e.g. residential or non-residential). This price structure is
generally considered less effective in encouraging water conservation.
Water Supplier Services - Water used for public services such as hydrant flushing, ice skating rinks,
public swimming pools, city park irrigation, back-flushing at water treatment facilities, and/or other
uses.
Water Used for Nonessential Purposes - Water used for lawn irrigation, golf course and park irrigation,
car washes, ornamental fountains, and other non-essential uses.
Wholesale Deliveries - The amount of water delivered in bulk to other public water suppliers.
