Project Location: , California
Client: California Department of Water Resources
Synopsis of work:
Designed for water conservation, the Citrus Reservoir holds 400 acre-feet of water and houses a new pump station with eight pumps that lift water 715 feet to a forebay tank at the Crafton Hills Pump Station.
For construction of this project, crews excavated native rock and sand and produced crushed rock products from the reservoir. The aggregate was transported for use on another Ames project being constructed 14 miles from the reservoir. The project scope included massive earthwork, structural concrete and installation of pipeline and liner.
The Crafton Hills pump station facility included the expansion of the Citrus and Cherry Valley stations that pump raw water to much of the state’s Riverside and San Bernardino Counties.
The main facility at the Citrus location adds eight vertical turbine pumps, a switchyard, air chambers, an office building, and a storage building. The other two facilities required extensive start-up, testing and commissioning of owner-furnished pumps, switchgear, and associated electrical equipment.
During a planned month-long shutdown of the Crafton Hills and Cherry Valley stations, crews replaced valves, installed new piping, and put in a completely new electrical control system. The vast undertaking required gutting the entire electrical system and integrating old systems components with new equipment. The installation included the program logic and testing, and ensuring the entire plant comes back online at the end of the outage.
A portion of the work was performed near an endangered kangaroo rat habitat. Before accessing this work area, a biological expert performed an extensive audit over multiple, consecutive nights. Once the area was cleared for work, Ames installed temporary exclusion around the site while work operations were being performed. The project was completed two and one-half months ahead of schedule.
