In preparing the specifications for this well, it was recognized that Well No. 3 alone would not likely be adequate to provide the entire water supply necessary to meet the rapidly expanding demand for water. The table below is a brief summary of the City's water utility supply. Ramsey Water Utility Raw Water Sources Source (GPM) MGal/Day System Capacity with Source Out of Service 0VIGal/Day~ Well No. 1 1000 1.44 2.72 Well No. 3 1000x 1.44 2.72 City of Anoka 7002 1.00 3.16 Well No. 2 200 0.28 3.88 Total 2900 4.16 ~Anticipated capacity 2Maximum allowed by agreement with the City of Anoka. The peak day waterpumpage this past summer has been 2.4 million gallons, which compares with the forecasted 1996 summer demand of 2.8 million gallons. The mid-summer 1997 peak day demand is fotcast to be 3.5 million gallons. If any three of our four City sources would become inoperable, the utility would be unable to meet 1997 peak demand, even with the addition of Well No. 3. It is possible that Well No. 3 may produce more than the desired 1000 gpm, or that forecasted growth ma, y not materialize, in which case the deficiency may not occur. Nonetheless, it would appear prudent to anticipate constructing Well No. 4. The engineer. . prepar'~xt specifications such. that the City could "lock-in". a price on this additional well if desrred. Therefore, the attached b~d includes the constmcnon of a second well, however, the specifications all~>w the City to terminate after the construction of Well No. 3. This project represertts only the construction of.the well itself. We currently anticipate a second contract including the well house and connecting watermain plans to be finished and bid in October. Better cost .comparison against the total project budget of $400,000 can be made at that time. Bids were received on Friday, August 16, 1996, from five contractors. A summary of the bids are provided below and a copy of the complete bid tabulation is attached.
