<br />. <br /> <br />. <br /> <br />. <br /> <br />TOWN OF NUCLA <br />RAW WATER IRRIGATION <br />PHASE II-B <br /> <br />BACKGROUND DESCRIPTION <br />The Town ofNucla in 1992 started to experience treated water shortages <br />during the summer months due to heavy outside watering at Town Park and <br />the schools athletic fields. This led to a water tap moratorium while we <br />studied other options. It was decided after an engineering study (Armstrong <br />Engineers) that it would be cost effective to do a raw water (untreated) <br />system in addition to our treated water system. The biggest advantage to <br />this system was that it would be gravity flow, and would require no <br />treatment other than screening, Water available to Town is 435,456,000 <br />gallons. The total raw water users are 150 . Total in-town domestic water <br />users are 400. <br /> <br />PROJECT DESCRIPTION <br />This project consisted of installing 11,500 feet of 4 inch rve, Main, 28-4 <br />inch gate valves along with associated T's and valve boxes. The Town also <br />installed a headgate. wier and meter at a higher elevation tor increased <br />pressure and with long term planning of using a three million gallon storage <br />reservoir, the Rainbow Reservoir (already in place), at a later date, The <br />project has also metered 41 old sites and 75 new ones tor a total of 113 <br />residences, 1 park and 2 school athletic tlelds. <br /> <br />PROJECT ENTAILMENT <br />After completing phase II-A of this project it became apparent that rock <br />removal was becoming e:\.1:remely expensive due to labor and bedding costs. <br />It was decided to try a Vermeer 550 Rock Trencher. This machine was <br />capable of doing 11,000 teet per day depending on soil conditions. Tests <br />showed that it was capable of 8 feet per minute in the hardest of sandstone. <br />It also turned the rock into a sand-like material that was used for bedding. <br />This saved the Town the money tor bedding and the expense of hauling and <br />disposing of the unusable rock. The first phase of this project took three <br />months to do. approximately 1,200 feet per season. This shortened the pipe <br />laying to approximately 60 days, The next section of this project was to <br />install meters on Raw Water intake on new and existing customers. <br /> <br />1 <br />
