Avenue 54 Sanitary Sewer Pipeline Project

Avenue 54 Sanitary Sewer Pipeline Project

The planned sanitary sewer pipeline project will serve an area of approximately 7,500 acres, of which 3,000 acres are within the Coachella Sanitary District boundaries and 4,500 acres are in the City's Sphere of Influence (SOI) region. The proposed sanitary sewer pipeline would be extended as a 12- to 15-inch diameter line from Van Buren Street at Avenue 52 south to Avenue 54 and a 30- to 42-inch diameter line from the intersection of Van Buren Street and Avenue 54 extending east and connecting with the existing 54-inch line at Polk Street. Construction of the pipeline will occur entirely within the existing right-of-way (ROW) of the affected roadway alignments. It will occur along section lines in the center of the respective ROW's, with the exception of the area along Avenue 54 from Van Buren Street to Harrison Street. This segment will be placed six feet north of the section line to avoid Augustine tribal land. The sizing of these lines is based on "ultimate" flows which are beyond the City's Sewer Master Plan projections for 2015. Construction will consist on conventional trench excavation methods, with trench depths ranging from 10-14 feet in depth. The portion of the pipeline crossing under Highway 111 and the Union Pacific Railroad will be constructed using a jack and bore method as required by Caltrans and the railroad operator. The casing pipe for the undercrossing will be a 60-inch diameter steel pipe with a 42-inch diameter carrier pipe installed inside.
