The reservoir could be moved to a»'oiher <br />location, provided a suitable site can be obtained. The preferred location for the tower <br />would be near Old Crystal Bay Road, either nonh or south of TH 12. The water system is <br />designed to keep the supply (well) and storage (tower) separated. This ghes the greatest <br />efficiency in providing fire flow to any area within the distribution system. <br />The proposed elevated tower designs shown on the attached plan provide the most cost <br />effective opuons. Whenever the designer varies signiflcantly from the options showu costs <br />increase signiflcantly. (S1.25/gal. to Sl.50/gal) We can develop additional design options if <br />desired by the City. <br />The <2ity has the choice of either elevated or ground storage. The elevated tank would be <br />approximately 145* high and the ground water reservoir would be approximately 60 ’ high. <br />The types of storage seieaed depends on the desires of the Qty and the overall system <br />economics. It is desirable to have some elevated storage on any water distributor system. <br />The Orono system will have only one reservoir for a number of years so we would <br />recommend that It be elevated. The operation and maintenance cost for the ground water <br />storage system is generally higher than for elevated storage. The booster pumps necessary <br />to get the water from the ground reservoir to the distributor system result in increased <br />construction and operaUon costs. <br />Please contact this office if you have any questions. <br />Yours very truly, <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC. <br />Clenn R.
