Slack Area Wastewater Collection System

Slack Area Wastewater Collection System

The proposed project would install approx. 9,000 linear ft. (LF) of 8-inch vitrified clay pipe (VCP) sewer mains and approx. 38 manholes, of which approx. 1,300 LF and six manholes (distributing approx. 1.5 acres) would be constructed in unpaved easements at the southern end of the project area. These unpaved easements are partially located along the Calimesa golf Course landscaped areas and un-landscaped portions of hillsides on private lots between the golf course and residences. A concrete-lined channel at the southern terminus of 3rd St. may be disturbed for the construction of a new wastewater pipeline oriented north/south between the existing pipeline at the 3rd St. terminus at the golf course and 2nd Place. The majority of the project would be constructed in paved streets. The sewer would be constructed with a minimum depth of cover of seven feet unless special construction is required. Manhole spacing would be 350 feet or less and manholes would be required at the end of each line, at a change in grade or sewer main size, at a change in alignment, or at any intersection of two or more sewer mains.
