<br />of the Plan will provide a further savings of500 area-feet a year. As the City's gpcd is <br />reiatively low compared to other cities in the Denver metro area, the 500 acre feet of <br />savings will principally come from expansion of the non-potable and reuse systems. <br />Another potential savings program is the plumbing retrofit program. This is a viable <br />option as most of the housing in the City was constructed in the 1950's and 1960's. <br />The City's water usage has declined significantly over the 2000 to 2005 period. Some of <br />the decline is likely a result of weather patterns and watering restrictions that were <br />imposed in 2002. The City also enacted several water savings measures and programs <br />during this period. In 2002, the City spent approximately $25,000 on conservation kits <br />(low-flow shower head, leak detection tablets, five-minute shower timer, rain gauge and <br />several education brochures) that were provided to homeowners. In 2004 and 2005, the <br />City spent approximately $30,000 for a rebate program for toilet replacements and for <br />high efficient washer purchases. Total annual treated water usage in the City in 2005 was <br />1,487,293 million gallons, 312 acre feet less than total treated water used in 200 I, the <br />first year of conservation related activities in Northglenn. Assuming a cost of $1 0,000 per <br />acre-foot to purchase and store an equivalent volume of water, this is equivalent to a <br />capital cost savings of $3.12 million dollars. These numbers illustrate the extraordinary <br />cost-effectiveness of water conservation that the City has already achieved. <br />The City approved a water conservation budget of approximately $15,000 in 2005 and <br />$20,000 for 2006 to maintain existing programs. The City has initiated the hiring process <br />for a full time ConsefVationistIW ater Education Specialist and will have the position <br />staffed by August 2006. <br />(d) Adequacy, stability and reliability of the entity's water system: <br />1. Water Supply Sources/Storage <br />Current Supplies and Storage <br />The City's primary water supply sources include Berthoud Pass Ditch, Church Ditch <br />inches, Farmer Reservoir and Irrigation Company (FRICO) shares and junior rights. <br />Water from all of these sources is delivered to Standley Lake for storage. The Croke <br />Canal, Farmers Highline, and Church Ditch are the primary delivery structures. Standley <br />Lake is located in Jefferson County. The firm yield for all of the City's water rights <br />currently owned is estimated at 2,900 af. Berthoud Pass Ditch diverts water from the <br />Frasier River Basin, through Berthoud Pass Tunnel to Hoop Creek which flows into Clear <br />. Creek. This water can be diverted from May 15 to October 15 and is principally delivered <br />via the Church Ditch. The City of Golden co-owns the Berthoud Pass Ditch with the City <br />of North glenn and shares in its water right. The City of Northglenn owns 18% of the total <br />Church Ditch inches and is two-thirds owner of the ditch structure itself. Ownership of <br />the structure allows Northglenn to use Church Ditch to deliver its Berthoud Pass water as <br />well as its Church Ditch inches. The Church Ditch operating season is April 1 through <br />October 31. <br />August 30, 2006 <br />
