<br />'. <br /> <br />. ' <br /> <br />-, <br /> <br />Conveyance Channcl <br />The Project conveyance channel provides the <br />means of collecting the salvaged ground water <br />I from the pipeline laterals and delivering it to the <br />Rio Grande. The channel is approximately 42 <br />miles long with the design capacity increasing <br />from 45 cfs to a maximum of 160 cfs. Bottom <br />widths range from 8 to 22 feet, and water depths <br />from 3.6 feet to 5.6 feet. The channel is lined <br />with 20 mil thick PVC lining covered with 12-16 <br />inches of aggregate and fill. <br /> <br /> <br />Figure 2 Conveyance Channel <br /> <br />./.--\ <br />;j <br /> <br />Structures <br />Construction of the conveyance channel <br />included two precast concrete siphons, seven <br />check structures, road crossings, four constant <br />head orifice (CHO) turnouts, one Parshall flume, <br />two pumping plants, one feeder canal turnout, and <br />one pipeline turnout. Extensive tree planting <br />called shelter belts have been planted in areas <br />highly susceptible to wind erosion. Drip <br />irrigation systems have been installed to water the <br />tree areas. <br /> <br /> <br />. ") <br />r ~ - . <br />"-.~ <br /> <br />Figure 3.

The <br />Programmable Master Supervisory Control <br />(pMSC) system consists of a master station in the <br />Project office, and 280 networked, remote <br />computers used for equipment control and data <br />acquisition. <br /> <br />Electrical <br />The Project area, which is for the most part <br />remote and inaccessible, is served by two public <br />utility companies. Electrical power is furnished <br />by Public Service Company of Colorado (PSCo) <br />and the San Luis Valley Rural Electric <br />Cooperative (REC). The Project is served by 96 <br />miles of overhead primary line, 31 miles of <br />underground primary line, and 42 miles of <br />underground secondary service. The Project also <br />has a solar-powered pumping system installed at <br />one well site. This stand alone photovoltaic <br />concentrator array pumping system was <br />developed and installed as a joint research project <br />of the Department of Energy and the Bureau of <br />Reclamation. <br /> <br />Operation and Maintenance <br />The Project is operated and maintained by <br />Bureau of Reclamation personnel. A contract <br />with the Rio Grande Water Conservation District <br />(RGWCD) provides for civil maintenance on <br />Project facilities. <br />The Project's overall operation is monitored <br />by a three-person operating committee to insure <br />the Project is being operated according to <br />authorizing legislation. This committee consists <br />of members appointed by the Secretary of the <br />Interior, Colorado Water Conservation Board, and <br />Rio Grande Water Conservation District. <br /> <br />Recreation Facilities - San Luis State Park <br />Recreation facilities were constructed at <br /> <br />(_ '" "... r.
