Preliminary Design <br />In the selection of the type of improvements needed to correct the <br />problem that exists with the Nunn water supply system (high nitrates) and <br />to improve the everall operation of the system, the following general <br />objectives for planning and design were established: <br />1. System capable of providin9 potable water that meets all <br />applicable standards for quality, and <br />2. Facilities which are practical and economically feasible, and <br />3, Adaptability to the existing system. <br />The proposed facilities are sized to serve the existing service area <br />and future population expected in the Town. The description of the recom- <br />mended improvements along with sufficient preliminary design details now <br />follows: <br />Raw Water Source and Delivery Facilities <br />The most important aspect of the improvements for the Nunn water <br />system are the improvements necessary to solve the nitrate problem and to <br />insure that Nunn will have a dependable water supply in the future which <br />will meet the State's water quality standards. As indicated in Chapter IV, <br />the treatment of the existing raw water is feasible by a Reverse Osmosis <br />(RO) process, However, due to the high operating costs in comparison to <br />the current user charge for water, and the requirements for the treated <br />water storage in conjunctien with the RO process, the recommended alternative <br />is the construction of new wells in the Lone Tree Creek Drainage. <br /> <br />31 <br />
