<br />tests showing the total hardness exceeding 200 parts per million.. Since water from well #1 is <br />not particularly desirable due to its hardness, this well has been used primarily as a backup <br />supply although during periods of high water demand it has been operated daily. Well #2 and its <br />pwnping facility was completed in 1979 and is used as the primary water supply source. <br /> <br />The surface water treatment plant, treating water from Pinos Creek, has a capacity of <br />approximately 450 g.p.m. The plant and improvements to the transmission pipeline were <br />completed in 1987-88. Since that time the treatment plant has been used intermittently primarily <br />during periods of peak. demand. Retention of qualified water treatment plant operators and <br />maintenance of the plant have been a difficult task for the Town. Also the water right for the <br />supply is occasionally curtailed due to its junior surface priority. Loss of the supply usually <br />occurs during late summer during periods of low stream flow. <br /> <br />Del Norte has two water storage reservoirs constructed of concrete located on Lookout <br />Mountain in the southwest comer of Town. The reservoir, which is connected to the lower <br />elevation section of Town, has a capacity of 272,000 gallons and the reservoir, which is <br />connected to the upper elevation section of Town, has a capacity of215,000 gallons. Due to <br />piping arrangements and pwnping head of the two well pwnps, only the lower reservoir can be <br />filled by the wells and pumps, but both reservoirs can be filled with the water from Pinos Creek. <br />To provide a way to supply water to the upper system during periods when the Pinos Creek. <br />supply is off, a booster pumping system was constructed to pump water from the lower reservoir <br />to the upper reservoir in 1985. <br /> <br />B. Water Usage <br /> <br />In order to develop an understanding af existing municipal water usage requirements, a <br />tabulation of water usage during the water years of 1991 through 1995 have been included in <br />Table 1. The water year consists of November of the previous year through October of the <br />current year. <br />
