The scope of the Reuse Project includes building a pipeline to carry secondary-treated effluent from the Wastewater Treatment Plant to Great Western Reservoir for storage prior to treatment and irrigation reuse, The existing potable water treatment plant would be modified for tertiary treatment to achieve water quality standards consistent with those specified in the Colorado Reuse Guidelines, Initially, Broomfield will deliver reuse water to irrigate a new golf course which is under construction at Interlocken Business Park. Reuse will ultimately be expanded to include City parks, open space, and other property. Using Great Western Reservoir as the storage component of the reuse project optimizes the utilization of wastewater effluent. Initially there will be between 1,100 and 1,400 acre feet of effluent available for reuse. The 400 acre feet of Coal Creek water and 300 acre feet of Walnut Creek water may also be available to add to the reuse supply, This water will be stored in Great Western Reservoir, The effluent will contribute to the water supply in the reservoir after the drinking water replacement program is completed and the Church Ditch water is sold, Every acre foot of reuse water supplied for irrigation will reduce an acre foot of demand on the potable water system, This will significantly reduce the seasonal peak day demand on the potable water system. The water saved will be used to support growth until 2020, deferring the need to purchase additional water rights, 5, Distribution system leak repair: The Utilities Division has an annual leak detection program to survey portions of the distribution system for leaks, The survey is carried out with the use of a leak noise correlator. The instrument is attached to a full pipeline and can pick up continuous noise if a leak is present. The survey helps to identify problem areas to be included in the annual water line replacement program. The water line replacement program is ongoing with a budget of approximately $300,0001 year. The Utility Billing Division has an ongoing meter replacement program with a $21,000 budget to replace old or leaking meters (approximately 400/year). The city has performed systemwide water audits annually since 1989, The audit identifies the metered consumption and known losses and subtracts them from the production volume to arrive at an unaccounted for water loss, The unnaccounted for water loss for the last five years averaged 3.8%. The industry standard for acceptable unaccounted for water loss is 0-5%, 16
