5. Water Audit Definitions and Background

6. Why are we doing this? The Illinois Environmental Protection Agency (IEPA) is committed to helping water utilities reduce system inefficiencies that increase the cost of service for utilities and their customers, inefficiencies that can also lead to increased demand for potable water in a way that negatively impacts the viability our state’s water resources. Over the next year, IEPA will work directly with water utilities and other partners on the specific problem of water loss from distribution systems. We need to better understand the extent of water lost from leaking pipes, lack of metering, meter inaccuracies and unauthorized consumption. At the same time, we hope to introduce strategies that can improve the efficiency of water production and delivery from water utilities of all sizes across the state. This should help save utilities and their customers substantial amounts of money relatively quickly, with a minimum of up-front investment The Illinois Environmental Protection Agency (IEPA) is committed to helping water utilities reduce system inefficiencies that increase the cost of service for utilities and their customers, inefficiencies that can also lead to increased demand for potable water in a way that negatively impacts the viability our state’s water resources.

8. Real Losses Also called Physical Losses – water that enters the distribution system, but never reaches a user. Includes: –Leakage on transmission and distribution mains –Storage tank overflows –Service Line leakage up to customer meter Reducing real losses creates an additional resource which reduces operating costs and can be used to defer capital expenditure Also called Physical Losses – water that enters the distribution system, but never reaches a user. Includes: –Leakage on transmission and distribution mains –Storage tank overflows –Service Line leakage up to customer meter Reducing real losses creates an additional resource which reduces operating costs and can be used to defer capital expenditure

9. Apparent Losses Also called Paper or Economic Losses – water that reaches a user, but is not properly measured or paid for. Includes: –Theft –Customer metering inaccuracies –Data handling errors Reducing Apparent losses increases revenue but creates no new water Also called Paper or Economic Losses – water that reaches a user, but is not properly measured or paid for. Includes: –Theft –Customer metering inaccuracies –Data handling errors Reducing Apparent losses increases revenue but creates no new water

10. Non-Revenue Water (NRW) Is the difference between the volume of water produced and the volume of water billed to customers It consists of three elements with different values in $/gallon: –Real Losses –Apparent Losses –Unbilled authorized consumption (political losses) Use this term instead of “unaccounted-for-water” Is the difference between the volume of water produced and the volume of water billed to customers It consists of three elements with different values in $/gallon: –Real Losses –Apparent Losses –Unbilled authorized consumption (political losses) Use this term instead of “unaccounted-for-water”

13. Water Balance Development Top-Down = “desktop” exercise using existing estimations and records –understanding of terminology and data required –only as good as the data that is used! Bottom-Up = detailed investigation into actual policies and practices –better estimates of water use by the fire department –quantify water used in line flushing –metering of all authorized uses Top-Down = “desktop” exercise using existing estimations and records –understanding of terminology and data required –only as good as the data that is used!
