Thompson Department of Environmental Health & Safety OCT 131987 Boynton Health Service 410 Church Street SE CLERK'S OFFICE - University of Minnesota Minneapolis, MN 55455 Re: Rosemount Rural Water System DGR File No. 3776 Dear Fay: I am enclosing the following items: 1. A revised map showing the location of the proposed facilities as suggested by the City of Rosemount in their letter to Mark Longson dated September 4, 1987. 2. A revised construction cost estimate for these facilities. 3. A revised operation and maintenance cost estimate for the same facilities. Service to the AVTI can be provided with very little change in capital costs because the new location selected for the wells is directly across County Road 42 from the AVTI and very little new pipeline will need to be constructed. The well pumps and hydropneumatic tank will need to be larger but the added cost to accomplish this should not be too significant. The net affect of the AVTI on the operation of the system will probably be beneficial, particularly during initial operation when the erratic water use pattern of the small number of rural users is "smoothed out" by the relatively large use by the AVTI. Also, as can be noted in the revised O & M cost estimate, the cost per Kgal. for the rural users has been brought down dramatically from our earlier estimate of $2.00 per Kgal. to $0.59 per Kgal. You will note in my current construction cost estimate that I've reduced the "contingency" line item. The 25% factor is still the same but now I've applied it only to the construction cost rather than to all costs as was done previously. 3460 West 38th Avenue 1051 Office Park Road 600 Sioux City Federal Plaza Bldg. 1113 Fast 14th Street Denver, Colorado 80211 West Des Moines.
