.

Education program. An active education program emphasizes
conservation through the use of pamphlets, brochures, and f11ms.
Presentations are made through community workshops, meetings, and
visitations to the schools. Residential guidelines covering landscaping,
vegetation types, mulches, and other water-saving suggestions are
available to all residents.

.

Handbook/training for employees. The District provides conservation
training and a water conservation handbook to all employees maintaining
public lands and open space.

.

Metering and rate structure. Centennial Water and Sanitation District
has been fully metered since its inception in 1981. In addition, the
District has a program to sample meter accuracy. Billing for water
service based on metered water use provides a strong incentive for
customers to use less water when compared to a flat-rate basis. In
Denver, a comparison of metered to unmetered households revealed
savings that ranged from 2 percent in the winter to 2S percent in the
spring (Brown and Caldwell, 1984).

.

Service pressure regulation. Centennial Water and Sanitation District
mandates the installation of water pressure regulators on domestic water
service lines to limit pressures to 6S psi. A study completed in Denver
indicated an average savings of about 6 percent in the lower pressure
homes.

.

Irrigation with nonpotable groundwater. The District maintains two
wells that provide nonpotab1e water for golf course irrigation. The
District also irrigates the Highlands Ranch Water Treatment Plant
landscape with nonpotable. water and irrigates the Marcy Gulch
WastewaterTteatment Planllahdscape with treated wastewater effluent.

.

Augmentation plan. The District utilizes an augmentation plan to extend
and make the best use of water resources. By "replacing" water in the
Platte River with increased return flows made up of direct surface ron-off
and well water used and discharged through the Marcy Gulch Wastewater
Treatment Plant, the District can make use of additional Platte River
flows. This issue is detailed further in Chapter 4.
