SCOPE OF WORK <br />Utility Water Loss in Colorado; Methods & Standards <br />Colorado Water Conservation Board <br />Project Overview <br />With the need for water conservation greater than ever, many drinking water utilities now offer <br />their customers tips on cutting water consumption in the home and workplace. But water utilities <br />also need to conserve water in their day -to -day operations. Water utilities not only bring us the <br />water we need, but they also consume large volumes of water and - without proper controls - can <br />waste or lose track of huge amounts of water. <br />With pressures mounting on our water resources, we must be water - efficient throughout the <br />entire lifecycle of human water use. With new methods of water auditing and loss control, water <br />utilities hold the potential to recapture large volumes of treated water as well as additional <br />revenues. Water Loss Control - conservation by water suppliers - is an essential function of the <br />drinking water industry. <br />Water Loss Control represents the efforts of drinking water utilities to provide stewardship and <br />accountability in their operations by reliably auditing their supplies and keeping their system <br />losses to a reasonable minimal level. <br />The purpose of this project is to research and develop a standard reporting methodology for <br />utility water loss in Colorado. "Water loss" is the current industry standard terminology for <br />unaccounted for water or line loss. There is currently little data on water loss in the State and <br />what data does exist has been developed in such a way making it virtually impossible to <br />adequately compare loss between agencies and to determine if loss is significant. <br />The International Water Association (IWA) and the American Water Works Association <br />(AWWA) have developed a standard methodology for determining water loss for municipal <br />water providers. This methodology has not been widely adopted or implemented in Colorado <br />(perhaps never). <br />The project will start by first researching and reviewing the current IWA /AWWA water loss <br />procedures and consulting with Colorado utilities about their current water loss accounting <br />procedures. Based upon this review, the project team will develop a guidance document for <br />implementing the IWA/AWWA methodology in Colorado. The research team plans to take <br />advantage of number of existing public domain tools for utility level water loss evaluation. <br />The products of this research will be: (1) a guidance document and (2) a water loss accounting <br />tool. These products will be ready and available to assist Colorado in establishing uniform <br />practices for water loss accounting and to enable Colorado water providers to implement these <br />uniform practices. <br />Aquacraft, Inc. 303 - 786 -9691 <br />www.acivacraft.com mayer@aquacraft.com <br />
