<br />Cumnt as of: April 21, 1997 <br /> <br />Section 2 - Inventory. <br /> <br />2,1 Water Supply Sources/Storage <br />The primary potable drinking water sources for the City are six deep (> 1,000 ft) artesian wells <br />drawing from the San Luis Valley confined aquifer. There is also a shallow irrigation well which <br />serves part of the irrigation needs of the golf course and a small capacity well for the golf course <br />club house. Well number 1 at 701 Ross Ave is currently out of service due to a high arsenic level. <br />It is anticipated that this well shall remain off-line until some sort oftreatment process is designed <br />or implemented and shall only be used for emergency fire flows if necessary. <br /> <br />The City serves approximately 10,500 people through 2,400 taps. There are no significant <br />industrial users on the system. More than 80% of the peak sununer use is for lawn, park, and <br />recreational facility irrigation. The winter domestic demands run about 18% of sununer <br />requirements. <br /> <br />The system is served by two elevated tanks, one of 150,000 gallons, the other 500,000 gallons. <br />We also have a surface storage facility of320,000 which is designed primarily to provide an out- <br />gassing facility for one of the wells, but also serves a secondary function of additional storage. <br />The reservoir is close to the end of its service life. ,> <br /> <br />2.2 Water/Wastewater Treatment Capacity. <br />The City does not currently treat its water other than fluoridation at the Weber Well. The system <br />currently operates under a disinfection waiver from the Colorado Department of Health and <br />Environment. This waiver permits operation of the system without disinfection of our high <br />quality sources. It does require a high degree of preventive maintenance of the distribution and <br />storage system. <br /> <br />The Alamosa Regional Wastewater Treatment Plant was constructed in 1994/1995 and has been <br />in service since October of 1995" This facility serves the City of Alamosa and surrounding <br />conununities. Current average flows to the plant are about 1.7 MGD with design average flows <br />of2.57 MGD and design peak hydraulic flow of 4.75 MGD. This plant was designed with very <br />" " " " - conserVative" assumptions and includes-an 1(}7 gpcd inflow allowance, The: City is taking vel)' <br />aggressive measures to reduce this inflow amount. <br /> <br />3, <br />
