The Weaverville Community Services District (District or WCSD) is a publicly owned water agency operating under the direction of an elected board of directors. The District provides water to the communities of Weaverville, Douglas City, and Union Hill located in Trinity County west of the City of Redding, in northern California.

The existing District boundary encompasses approximately 12 square miles (7,780 acres). In the year 2001, the District served a population of about 3,800 with 1,498 individual services, and produced 302 million gallons of treated water.

Most of the District is in moderately hilly terrain with elevations varying from 2,720 feet (East Weaver Tank) to 1,650 feet (Douglas City). Most of the community, businesses, and industry are located along Highway 299 and Highway 3. The densest population centers are within a block of the two highways.

HISTORY

The District was formed in June of 1977 for the purpose of providing a public water system for the community of Weaverville. In May 1979, the District acquired and began operating the existing water system, which was previously owned by CF National (formerly Cal Pac). At that time, the water supply all came from a diversion on East Weaver Creek. The District began immediate improvements by covering a 2.1 MG open reservoir to meet California Health Department Standards. In 1984, the West Weaver Treatment Plant, which takes water from West Weaver Creek via the Moon Lee Ditch, was built to augment the water supply.

In 1987, further improvements were made to the system at the East Weaver Treatment Plant with the addition of a 0.42 MG tank, and installation of a new chlorine injection system. The West Weaver 0.42 MG water tank was also constructed during this time as well as major improvements to the distribution system with pipe sizes up to 12 and 14 inch diameter and several new pressure-reducing stations.

Even with these improvements, it was clear that the District would need a new water supply to make up for inadequate capacity in dry years and to allow for future growth. Consequently, in 1997 the Trinity River Treatment Plant (TRTP) was built in Douglas City, along with a 12-inch pipeline from Douglas City to Weaverville along Highway 299. To accommodate the plant a 0.3 MG tank, pump station, and PRV station were built near the old Gables restaurant site; furthermore, a 0.5 MG tank was erected at the end of Ransom road. A 2.0 MG tank was later erected to replace the in-ground 2.0 MG hydro-reservoir with the floating cover. The in-ground 2.0 MG reservoir has since had the floating cover removed and serves as an emergency water storage reservoir for fire fighting helicopters. At the same time, the District expanded to include Douglas City and the residents of Union Hill, and new water distribution systems were built in these communities. In 1998, the East Weaver Water Treatment Plant was upgraded with new filters.
