The last leak detection was performed during the summer of 1991. With <br />the computer monitoring system known as SCADA, Willows can monitor water flows_ A sudden, <br />unusual increase in flow indicates the possibility of a leak, which is then' checked by District <br />personnel. This computer system has proven effective in identifying large leaks. <br /> <br />Future Implementations: <br />By reducing leaks within the system, Willows Water District will reduce water losses. Leak detection <br />will locate areas of the system needing rehabilitation. This will help reduce the potential oflarge main <br />breaks that may occur when small leaks remain undetected for long periods. <br /> <br />The District will continue to contract to have the water distribution system checked every several <br />years for leaks. A master key map is being used to record the types of pipes encountered and to <br />locate water valves when repairs on the system are made. This has allowed the District to keep a <br />current record of the existing pipes and predict where rehabilitation may be needed in the future. The <br />District also currently replaces meters after they have registered 4,000,000 gallons. This helps to <br />minimize the chance of broken meters and promotes accurate measurements by the meters in the <br />individual homes. <br /> <br />11 <br />
