In terms of water conservation, these practices have led to a savings of approximately
30 million gallons over a three-year period.

As the development of irrigated park acreage increases, so have stand-alone irrigation
systems. District staff are achieving better irrigation control through an advanced centralized
computer control system and the conversion of stand-alone units with radio controllers. In 1993,
the District will complete a conversion of all "hard wire" controllers to a radio controlled
system.

Distribution System Leak Detection and Repair. Through a leak: detection program,
an agency can reduce water loss due to underground leaks. In addition to reduced water loss,
benefits include favorable public opinion; savings in water treatment and energy costs;
maximized capacity of existing water system, distribution, and storage facilities; and reduced
costs. Several elements of the District's leak detection program are described below:

As part of the overall maintenance program, District staff operate all water system valves
and hydrants at least once every 12 months and visually inspect the valves, hydrants, and main
line rights-of-way for evidence of leaks. If a leak is suspected, the District utilizes sophisticated
leak detection equipment in a systematic method to pinpoint the location of the leak and initiate
repairs. The leaks and repairs are documented for future reference.

In addition, the District employs a meter verification program for commercial meters to
verify meter accuracy. Billing records are also reviewed for unusually high water usage.
Beginning in 1993, the District will initiate a residential meter testing and rotation program to
complement the commercial sector program.

To minimize the occurrence of corrosive-based leaks in the distribution system, the
District has instituted a program for monitoring potential corrosion within the system in order
to prevent deterioration of the pipelines.

-Promotion afWater Use Efficiency. The District has promoted water conservation
through school programs since 1987. In addition, a public outreach program of education and
information emphasizing conservation has also been developed including:

· - Pamphlets, brochures, and fIlms.

· Presentations at community wooohops, meetings, and schools.

· Residential guidelines for landscaping, vegetation types, mulches, and
other water-saving suggestions.

· Conservation training and a handbook for all employees maintaining
public lands and open space.

· Presentation of Xeriscape materials to all new homeowners.
