Flume 7 Well and Transmission Main Pipeline Replacement Project

Flume 7 Well and Transmission Main Pipeline Replacement Project

The City of Riverside intends to install the proposed Flume 7 raw water production well in the Riverside Groundwater Basin and construct ~1,550 linear ft (LF) of 30 inch diameter steel transmission pipeline replacing the existing 48 inch diameter transmission pipeline. The proposed Flume 7 well is located in the Riverside North Groundwater Basin and within the City's existing right-of-way and easements. The Project site is within the city of Colton just beyond the westerly extend of Washington Street. The City intends to treat the water extracted by the Flume 7 well at the new John W. North Treatment Plant, located ~1,500 ft to the southwest of Flume Well 7, and export this water to the City's service area in Riverside County. Portions of the Flume Transmission Main have been replaced in 1982 and again in 2007. The remaining reach (1,550 LF) from south of the Santa Ana River to the John W. North Treatment Plant, will be replaced as part of this project. This reach is located within City-owned right-of-way and pipeline easements. The pipeline will be trenched into the river levee. The well will have provisions for and emergency power hookup so that a portable trailer mounted diesel-fueled generator could be brought out to the site. This generator, however, would not be stored on site when it is not in use. The well is anticipated to have a maximum pumping capacity of 2,500 gallons per minute (GPM).
