Crafton Hills Reservoir Enlargement East Branch Extension Phase II involved various phases and projects to reach the ultimate goal of expanding the Southern California water resources system. Our job as Atlas was to provide DWR with quality assurance and materials testing using the 1,000 square foot onsite Mill Creek Laboratory constructed for the various projects. The entire project consists of approximately six miles of 66-inch and 72-inch pipeline (Mentone Pipeline), a new 560 acre-foot reservoir (Citrus Reservoir), expansion of the existing reservoir from 85 acre-feet to 225 acre-feet (Crafton Hills Reservoir), a new 135-cfs pump station (Citrus Pump Station), and installation of an additional pump house and storage tank (Crafton Hills Pump Station) to increase the capacity to 52 cfs.
- Atlas provided on-site inspections as well as on-site laboratory testing to expedite work.
