BMPs are defined as established practices and techniques that have shown documented improvements in water use efficiency. 5.1 Water Audit and Leak Detection /Repair Program The City conducts monthly and annual pre- screening water audits in an effort to determine and control unaccounted water usage. Unaccounted usage is determined through analysis of total water production, metered sales and other verifiable beneficial /maintenance water uses such as fire fighting and line flushing. The City also estimates water losses from known leaks. In 2000, the City implemented a system -wide leak detection program, with one quarter of the system scheduled to be surveyed each year. Leaks are detected through sonic sounding of all service lines, fire hydrants and valves using leak detection equipment. Reports are generated throughout the survey period and leaks are repaired as soon as practicable, with precedence given to larger leaks. In addition to the annual leak survey, the City conducts ongoing leak detection activities such as periodic visual inspection of lines and a 24 -hour leak report hotline. Suspected and reported leaks are investigated immediately and repaired as soon as possible.
