Project Description

Sacramento Suburban Water District (SSWD)
Antelope Pump Back Project

Northern Division, Water Treatment

Antelope, CA

The Sacramento Suburban Water District (SSWD) and the San Juan Water District (SJWD) joined forces on a project to install a new 10,000 gallon per minute pump station that would be designed to allow SSWD to pump excess groundwater to SJWD and others in the event of a major drought or emergency. W.M. Lyles Co. was contracted on this design-build project to perform various scopes of work for this joint project including:

  • Pump Station – Installation of a new pump station and building which will send flow from one water district (SSWD) to another (SJWD) adjacent to an existing pressure reducing station. Work included three new vertical turbine pumps, below-grade encased pump cans, tie-ins to existing 48” domestic water lines, slab on grade, and a pre-engineered metal building enclosure. Re-grading and paving of the site. Associated electrical work for the pumps and building, and a diesel standby generator.
  • New SMUD Utility – Approx. 1,000 LF of new SMUD utility lines to provide power to the new pump station, adjacent to a public sidewalk and road. New vaults and tie-in to the existing utility.
  • Flowmeter Replacement – Installation of two new buried flowmeters (30” and 48”) into existing water mains (one below a public road) involving cutting new sections of pipe into the lines, and installation of new pre-cast vaults to house the flowmeters. Removal and abandonment of existing probe-style flowmeters.
