<br />A ten inch line has recently been installed east on County Road 88 from County Road 29 to <br />Pierce. Because of high nitrate problems with Pierce's shallow groundwater supply they are in <br />the process of obtaining 100 percent of their water supply from the Water District. With the <br />installation of the new ten inch line, the Water District is now able to provide better pressure to <br />Pierce and the Water District services east of Pierce. <br /> <br />When the Town ofNunn connects to the system, the Water District may loop the ten inch line <br />through Pierce or add an additional six inch line from County Road 88 to County Road 90. The <br />Water District has included this cost in their system-wide demand fee estimate for the Town of <br />Nunn. <br /> <br />The Water District system is pressurized by the NWCWD Tank No.6 which is located four <br />miles west of Pierce. The' high water level in the Tank is at an elevation of 5250 ms!. and the <br />high water level in Nunn's elevated storage tank is 5305 ms!. Therefore, a booster pump will be <br />installed at the intersection of County Road 29 and County Road 88. Power is available at this <br />location. <br /> <br />111 PROPOSED NUNN WATER SYSTEM <br /> <br />Nunn's potable water supply will consist of water pumped from their Well No.3 ("Under the <br />Tower We1J") and water delivered from the Water District system. A schematic of the proposed <br />water system is shown in Figure No.2. Nunn's 50,000 gallon in-town elevated storage tank <br />(Storage Tank No. I) will continue to be used to pressurize the water system. The existing <br />100,000 ga1Jon storage tank north of Town (Storage Tank No.2) will be used in a similar manner <br />as it currently being used. As the demand in the Town requires, water will be pumped from <br />Storage Tank No.2 to Storage Tank No. I using the existing in-line Tank No.2 Booster Station. <br /> <br />A computer system will be used to program the operation of the water system. The existing Well <br />No.3 pump house will be used to house the master controls for the system. Pressure transmitters <br />will be insta1Jed at both tanks to sense the water levels and provide signals back to the master <br />control as required. <br /> <br />Radio signals will be sent and received by telemetry installed on the elevated storage tank, <br />Storage Tank No.1. Telemetry sites will also be set up at the NWCWD Nunn Booster Station, <br />Tank No.2 Booster Station, and at Storage Tank No.2. <br /> <br />The system will be operated to utilize Well No.3 to the fullest extent possible. When Well No.3 <br />is not able to keep up with demand and the water level in Tank No.2 is low, the NWCWD Nunn <br />Booster Station wi1J be started. An electronically controlled valve will be installed at the existing <br />Tank No.2 Booster Station so that Tank No.2 can be filled during low demand periods. <br /> <br />2 <br />
