1. EXECUTIVE SUMMARY
■ City Proj ect No. 320 involves the extension of a trunk watermain to serve existing businesses
seeking potable water service and fire protection along Trunk Highway(TH) 52, north of
' 140 " Street and along TH 55, east of TH 52 to just beyond Doyle Path. This project is the
second part of the East Side water system improvements, with the proposed water tower
project as the first part. The final part of the improvements would involve the connection
' of this water system to the rural wells with a new larger trunk watermain system located
along CSAH 42. A map showing the project location is shown on Figure 1.
' The east side watermain extension will connect to the existing rural water system and the
proposed new water tower site located south of County Road 42 and east of TH 52. The
proposed improvements include the construction of approximately 12,700 lineal feet of 12-
inch DIP watermain and 2,400 lineal feet of 8 -inch DIP watermain and appurtenances to
provide potable water service and fire protection to facilities adjacent to the watermain,
' namely the Koch administration building, Continental Nitrogen, Spectro Alloys, and Dixie
Petro Chemical (DPC). An additional option analyzed in this report includes a continuation
of the watermain to the south, to 140 ' Street and a connection to the existing rural water
system, to provide a looped system.

2. INTRODUCTION
2.1 Authorization
On May 2, 2000, the Rosemount City Council authorized the preparation of a Feasibility
Report to address the extension of watermain to provide potable water service to adjacent
properties along TH's 52 and 55. This project has been designated as City Project No. 320.
2.2 Scope
This report addresses the construction of a trunk watermain along TH 52 from 140' Street
to TH 55 and along TH 55 from TH 52 to just beyond Doyle Path to provide potable water
service and fire protection to adjacent properties. This project will include the construction
of approximately 12,700 lineal feet of 12 -inch DIP and 2,400 lineal feet of 8 -inch DIP
watermain and appurtenances. An additional option to this project includes the continuation
of the 12 -inch DIP watermain to the south along the railroad right -of -way and MCES
property to connect to the rural water system at 140`' Street, providing a looped system. The
project as proposed will connect to the existing rural water system, and new water tower
located south of County Road 42 and east of TH 52. Installation of the trunk watermain is
anticipated to be within the Mn/DOT right -of -way or private easements.
2.3 Data Available

3. GENERAL BACKGROUND
' 3.1 Project Location (See Figure 1)
' The proposed watermain improvements are located north of 140 Street along TH 52 to
Koch's East side complex and along TH 55, east of TH 52 just beyond Doyle Path to Spectro
' Alloys.
3.2 Existing Conditions
The primary area where the trunk watermain is proposed to be installed is within the right -of-
ways of TH's 52 and 55. The terrain in this area consists of road ditches, several areas of
' trees and brush, and other vegetation.
Numerous private utilities exist within and adjacent to the right -of -way. Sprint has several
' fiber optic cables located along the south side of Pine Bend Trail from TH 52 to TH 55,
within the right -of -way. Sprint also has telephone cables located along and crossing TH's
52 and 55. These are all copper cables and are critical communication lines for the
' surrounding businesses. Northern Natural Gas (Enron) has a 12 -inch diameter high pressure
steel line crossing TH 52. Peoples Natural Gas has pipelines along TH's 52 and 55 in
parallel alignment with the proposed watermain. NSP has two TH 52 crossings along with
i a distribution pole line along the east right -of -way and a transmission pole line along the
west side of TH 52. Koch Pipeline has a 6 -inch propane line, two 16 -inch crude oil lines,
' a 12 -inch and 8 -inch refined product line all along and crossing TH 52. Coordination with
these private utility companies is crucial to the safe installation of the watermain. Exact
locations of all these utilities is being verified and may have an impact to the alignment of
the proposed watermain, as well as construction within the highway right -of -way.
The existing properties currently are not served by City water and exist on private water
' systems. The existing rural water system and the new water tower site are designed to
provide domestic water supply service and fire protection to this eastern service area. The
existing businesses that currently need service include Koch Refinery, Continental Nitrogen,
' Dixie Petro Chemical (DPC), and Spectro Alloys Corporation. Koch Refinery has extreme
fire protection demands and will need to maintain a separate fire protection system, but will
use the City water for potable water needs. Continental Nitrogen needs City water for
' potable water use only. DPC needs City water for processing and potable water only.
Spectro Alloys has a sprinkler system installed in their facility and is required to hook up to
City water for fire protection. Based on projected pressures in the area, it is likely that
' Spectro Alloys will need to install a booster pump to meet their internal sprinkler system
requirements.

PROPOSED IMPROVEMENTS
Watermain (See Figure 2)
The proposed trunk watermain will connect to the existing 12 -inch DIP stub located at
140" Street and TH 52, west of Conley Avenue, and will extend north along the east side of
TH 52 for approximately 6,000 feet and continue along Pine Bend Trail to TH 55 for
approximately 900 feet, while providing service to Continental Nitrogen. The watermain
will then extend along the south side of TH 55 for approximately 1,200 feet, and will cross
TH 55 and extend east along the north side of TH 55 for approximately 4,000 feet to just
beyond Doyle Path to provide service to Spectro Alloys. The proposed watermain will also
cross TH 52 with 12 -inch DIP line just south of Pine Bend Trail with an 8 -inch DIP line to
serve Koch Refinery's east side complex. The watermain will extend through jacked casing
pipe at crossings under TH's 52 and 55. Water service lines from the trunk watermain will
be extended to the individual properties as required. An 8 -inch DIP water line will service
Koch Refinery's east side complex, a 4 -inch DIP pipe will serve Continental Nitrogen and
a 12 -inch DIP water line will serve Spectro Alloys and DPC. Hydrants with six -inch leads
and gate valves will be placed at high and low elevation points along the proposed watermain
line along with other locations to maintain an approximate 1,200 -foot spacing. Gate valves
will be placed every 1,200 feet and at crossing and services.
The proposed watermain includes installation in the Mn/DOT right -of -ways of TH 52 and
TH 55, pending permit approval. As described in the existing conditions section, there are
several private utilities located in the Mn /DOT right -of -way. Their exact location is being
verified and potentially poses tight construction limits for installation of the proposed
watermain. Use of a trench box, supporting the private utilities and protection of the
proposed watermain is anticipated to be needed during construction. Private easements may
need to be acquired to work around all the utility conflicts. These costs were not included
in the cost opinion, however it appears that the adjacent property owners would be agreeable
to provide easements if necessary. There is a rectifier present near Koch's site and most
likely the trunk watermain will need to be connected to Koch's cathodic protection system
to avoid damage to the pipe. Using PVC pipe may be an option instead of using DIP to
further protect the watermain from any degradation. These details will be worked out during
design. For this feasibility report we will consider using 8 -inch DIP, as it is more costly than
PVC pipe.
The system as proposed consists of a long dead end line, which can create issues with water
quality and possible inconsistent service. In an effort to accommodate a looped system, a
possible option would be to continue the extension of the 12 -inch DIP watermain for
approximately 5,000 feet from TH 55 south to 140' Street along the railroad right -of -way
and adjacent to the Rosemount wastewater treatment plant. This system would connect into
the existing 4 -inch PVC line along 140" Street, which is part of the City of Rosemount's
Rural Water System. While connection to the 4 -inch system is not ideal, it would provide
City of Rosemount Ar East Side Watermain Extension and Appurtenant Work
Feasibility Report - City Project No. 320
WSB Project No. 1252 -00
Page 4
consistency in the system which is essential for many of the benefitted businesses. This
proposed 12 -inch optional line will include auguring under railroad tracks at TH 55.
Hydrants and gate valves will be placed along this line to maintain an approximate 1,200 foot
spacing. Private easements will need to be acquired for this option and are not included in
' the cost opinion.
' This proposed system is considered to be the second part of the East Side water system
improvements plan, following the proposed water tower project. It is anticipated that this
project can be constructed in time to connect with the new water tower site, which is to be
completed by July of 2001. The timely completion of this project will allow the third phase
to proceed, which includes the extension of a trunk watermain along County Road 42 to the
rural well system. This third phase will provide a larger and more efficient water system,
' increasing the rate at which the new water tower can be filled and providing a more reliable
water source.
' 4.2 Permits / Approvals
Permits will be required for this project from the Minnesota Department of Health for the
' watermain extension.
' Permits from the Mn/DOT will be required for any work performed within TH 55 and TH 52
rights -of -way.
Railroad permits will be required for crossings and work performed within the rights -of -way.

' 5.2 Funding
The City's policy for assessments is to assess the cost of a 12 -inch watermain in commercial
or industrial zoning areas and 8 -inch watermain in residential areas. These assessments are
figured out at $18 /front foot or at a rate of half the cost of installation per benefitting side.
Funding for the project will be collected from special assessments to the benefitting
properties and through the City's Water Core Fund. Much of the property adjacent to the
proposed watermain is undeveloped, with no immediate development plans. Further,
because properties across the highway from the watermain installation are difficult and
expensive to service, the assessments are figured for the length of adjacent property. In the
case of Continental Nitrogen, the front footage is considered the shorter of the two sides.
Koch Material is being served by an 8 -inch service line, and will not be charged the same
rate as the other properties, instead they will be charged for 100% of the costs to service
them. Service costs for Koch, DPC, Continental Nitrogen and Spectro Alloys are included
in the following table. Yearly costs are estimated at an 8% interest rate for 10 years.
