<br />In addition, the City of North glenn has junior water rights on Clear Creek during "free <br />river" conditions. Free river conditions imply that the flow in the river is high, all senior <br />water rights are being met, and no call on the river exists. During drought, the flow in <br />most rivers is low and the call is too senior to allow the City to divert these rights. <br />Northglenn has insufficient water supplies to meet drought year demands. In 1976, <br />Northglenn developed an innovative agriculturaVmunicipal partnership to enhance the <br />City's water supplies. <br />The Northglenn/FRICO exchange gives the City the first use of agricultural supplies in <br />Standley Lake and the City returns treated effluent to the irrigators. This agreement has <br />effectively extended Northglenn's supplies by the amount exchanged without requiring <br />the City to purchase water rights or expand storage. In order to meet 2003 drought <br />demands, Northglenn borrowed 1,800 af of agricultural supplies and also imposed <br />mandatory outdoor watering restrictions. The amount ofFRICO agricultural supplies <br />available for exchange to Northglenn is diminishing due to development in the area <br />historically irrigated. Part of the replacement source of this water will be achieved <br />through water conservation. <br />2. Water/Wastewater Treatment Capacity <br />Potable Water Treatment and Storage I <br /> I <br />The City's raw water supply is stored in Standley Lake. Water from Standley Lake flows <br />by gravity through a pipe to a terminal reservoir with a capacity of 40 million gallons. <br />The terminal reservoir is located at the Northglenn Water Treatment Facility (WTF) at <br />2350 West l12th Avenue. The WTF has 16 million gallons per day (MGD) capacity. The <br />City's peak and average daily demand are 10.6 MGD and 4.4 MGD, respectively. In <br />2002, the City built a new finished water storage vessel with a capacity of 3 million <br />gallons. Combined with three City of Northglenn Water Conservation Plan 10 existing <br />storage vessels, the City now has 7.75 million gallon of finished water storage. <br />Waste Water Treatment and Storage <br />The Northglenn wastewater treatment facility (WWTF) is located in the West Y2 of <br />Section 36, TIN, R68W in Weld County at the intersection of Weld County Roads 2 and <br />11. Treatment consists of an aerated lagoon system with discharge through Bull <br />Reservoir (4,200 af capacity) to Bull Canal, Thompson Ditch, or Big Dry Creek (a <br />tributary to the South Platte River). There are three cells in each of two parallel trains of <br />aerated lagoons. Northglenn will require a capacity of 4.94 MGD to provide service <br />within its corporate boundaries at build out in 2020. Northglenn's National Pollutant <br />Discharge Elimination System (NPDES) permit was reissued January 27,2002. A <br />compliance schedule to meet new ammonia limits by June 1,2006 was included. The <br />City is currently in the process of upgrading the WWTF to a 4 MGD, 3-stage biological <br />nutrient removal (BNR) system. The upgraded facility will have nitrification, <br />denitrification and biological phosphorus removal capacity to meet permitted and future <br />effluent 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 WWTF could <br />August 30, 2006 <br />
