Collection
Systems Each
of the four wastewater treatment plants within the individual tributary
areas treat sewage from an upstream collection system. The area served by
the Huston Creek Treatment Plant is the largest, providing service for 75
percent of the sewered area. The service area for the Seeley Creek Treatment
Plant comprises the remaining 25 percent within the present boundaries of
the District. The Cleghorn
Treatment Plant (owned by the District) and the State owned Pilot Rock
treatment plants provide service to areas whose collection systems are owned
and maintained by the California Departments of Parks and Recreation and
Forestry. The District's sewage collection system was constructed during four different periods of time (1952,1968,1975, and 1977). Developers have installed other sewers throughout the District, totaling about 15,000 feet. Approximately 95 percent of the systems are composed of 8-inch main. Generally, only the pipeline from the last manhole in each collection main to a cleanout is 8-inch with some being 6-inch. Manholes are pre-cast concrete, cast-in-place concrete, or red brick built in place manholes. Within Assessment District No. 1, manholes do not have cones and are fitted with 40-inch frames and 24-inch covers. Clay pipe has rubber ring joints at 5-foot intervals except for the VCP system constructed in 1952. In that Assessment District (No. 1), joints are spaced every 3 feet and were made by caulking with jute and hot tar. Joints in PVC pipe are constructed with rubber rings, in Asbestos Cement Pipe with double o-rings rubber gaskets, and in ABS "truss" pipe joints are solvent welded. |
