<br />Potable Water Treatment and Storage <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 adjacent to the Northglenn Water Treatment Facility <br />(WTF) at 2350 West 112th Avenue. The WTF has 16 million gallons of treated water <br />capacity per day (MGD) capacity. The City's peal( and average daily demand are 10.6 <br />MGD and 4.4 MGD, respectively. In 2002, the City built a new finished water storage <br />vessel with a capacity of 3 million gallons. Combined with existing storage vessels, the <br />City now has 7.75 million gallon of finished water storage. <br /> <br />Waste Water Treatment and Storage <br />The Northglenn wastewater treatment facility (WWTF) is located in the West 'ii 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. <br /> <br />Note: Additional water treatment, storage and waste water information can be found in <br />the state-approved City of North glenn Water Conservation Plan on file at the CWCB <br />office. <br /> <br />c. How the grant program monies will be used: <br />The grant monies will be used to purchase 500 low flow toilets that use 1.6 gallons per <br />flush or less. These new toilets will save an estimated 20-25 acre-feet of water per year. <br /> <br />D. Project Monitoring <br />A sampling of 25 homes will be analyzed pre and post toilet replacement. The water <br />conservationist will go to the 25 residences and temporarily install a flow meter to <br />measure gallons per flush on the old toilets and again after the new toilets have been <br />installed. This will give an estimate of how much water is being saved overall by the <br />replacement of 500 toilets in Northglenn. Additional savings estimates will be made by <br />analyzing winter month usage both before and after replacement on the remaining 475 <br />homes to garner an estimated savings. Winter month usage will be monitored as it is <br />assumed that the vast majority of water usage is indoor usage and that outdoor water <br />usage and irrigation is at a minimum. <br /> <br />Additionally, surveys will be handed out to all toilet recipients for them to fill out after <br />installation of the toilet. The survey will request information including number of people <br />in the household to determine if numbers have changed from 2007 ( old toilet) to 2008 <br />(new toilet) which could skew the water savings estimates. Survey results will be <br />compiled as to effectiveness, approval ratings, and use. <br /> <br />7 <br />
