<br />City of Northglenn Water Conservation Plan <br /> <br />existing storage vessels, the City now has 7.75 million gallon of finished water <br />storage. <br /> <br />Waste Water Treatment and Storage <br />The Northg1enn wastewater treatment facility (WWTF) is located in the West Y2 <br />of Section 36, TIN, R68W in Weld County at the intersection of Weld County <br />Roads 2 and 11. Treatment consists of an aerated lagoon system with discharge <br />through Bull Reservoir (4,200 af capacity) to Bull Canal, Thompson Ditch, or <br />Big Dry Creek (a tributary to the South Platte River). There are three cells in <br />each of two parallel trains of aerated lagoons. Northglenn will require a capacity <br />of 4.94 MGD to provide service within its corporate boundaries at build out in <br />2020. At build out, 1.06 MGD of unused capacity will remain above the City's <br />needs. This capacity is available to the Cities of Broomfield and Thornton, <br />unincorporated Weld County, and others within the vicinity of the treatment <br />plant who may need wastewater treatment service. <br /> <br />Northglenn's National Pollutant Discharge Elimination System (NPDES) permit <br />was reissued January 27,2002. A compliance schedule to meet new ammonia <br />limits by June 1,2006 was included. The City is currently in the process of <br />upgrading the WWTF to a 4 MGD, 3-stage biological nutrient removal (BNR) <br />system. The upgraded facility will have nitrification, denitrification and <br />biological phosphorus removal capacity to meet permitted and future effluent <br />limits. The plant is designed to readily increase to a capacity of 6 MGD. <br />Additionally, ifmore stringent effluent limits are imposed in the future, the <br />WWTF could be upgraded to as-stage BNR process. Upgrades to the 3-stage <br />BNR process are scheduled to be completed prior to the June 1, 2006 compliance <br />date. <br /> <br />2.3. Existing Water Conservation Measures <br /> <br />To insure adequate supplies of water for drinking and other domestic uses for the <br />present and years to come, the City began implementing a water conservation <br />program late in the summer of2001. This program has included the conservation <br />measures described below. <br /> <br />2.3.1. Water-efficient fixtures and appliances, including toilets, urinals, <br />showerheads and faucets <br /> <br />1992 Energy Efficiency Law <br />The passage ofthe Federal 1992 Energy Efficiency Law set minimum <br />water use standards for toilets and showerheads. All new developments <br />are built with water efficient fixtures and appliances and many older <br />buildings have been retrofitted, leading to indoor water use savings. <br /> <br />Appliance Rebate Program <br />The City implemented a toilet and clothes washer rebate program in June <br />2003. Residents receive a $75 rebate for the purchase and installation of <br />low volume toilets. Commercial rebates are $50 per toilet. The <br /> <br />10 <br />
