I I I I I Mayor Pro tern Zimmerman asked what happens if there is no MUSA expansion allowed in this area. City Engineer Jankowski stated the water tower is not subject to the MUSA requirements, but the sanitary sewer is subject to MUSA. He noted the City already has two wells outside the MUSA and a third well being installed outside the MUSA. Mayor Pro tem Zimmerman asked why four wells are located within one area and are not spread out. City Engineer Jankowski stated that strategy was identified in the Water Utility Plan which identified where productive water formations would likely be. In that particular area, there is a bedrock water area which is why it was selected. He noted the wells were placed in a grid pattern since it lends itself to one well house to service two wells. Also, there is a question whether the City will take the quantum step to provide water treatment for aesthetic concerns. It would be more economical to construct a water treatment plant in one general area than to construct several. Councilmember Anderson asked if there i~"a danger of well drawdown. City Engineer Jankowski stated the aquifers are separated by an impervious layer so any wells in the sand and gravel formations would not be impacted by these large municipal wells. However, if the private wells were 200 to 300 feet deep, there is a possibility of interference from the drawdown. Fortunately, the area in question is open farm field with very few wells in the area. Councilmember Anderson commented that one thing which identifies a town is the shape and design of the water tower. She asked if the Council will have input on the design of the water tower. City Engineer Jankowski stated the issue of the logo to put on the water tower will need to be addressed and staff can provide input for the Council's consideration with regard to tower styles. He stated the consultant can provide pros and cons on different water tower styles. He explained that multi-leg tanks are economical for larger storage sized tanks and the two most likely tank styles with competitive bids are the spheroid (like the current tower) and hydropillar since they are the most economical for a 1.5 million gallon capacity. City Engineer Jankowski stated that the specification will be written so multiple styles can be bid but if the Council has a style preference it can be indicated in the specifications. He stated he will provide a report to the Public Works Committee or any interested Councilmember. Councilmember Connolly asked if the well is for current usage or anticipated MUSA expansion. She stated her concern is to not be paying for capacity that is not needed until the future. City Council/January 25, 2000 Page 22 of 34
