Featured Projects

Chandler Airport Water Reclamation Facility
CSW provided construction services for both CMAR projects for the City of Chandler that included a 15 MGD and 22 MGD upgrade. CSW provided constructability reviews and prepared two Cost Models for both projects in the early stages. The 15 MGD project was broken up into 2 GMP’s in which were bid at the 60%, 90% and Issued for Construction Phase. The 22 MGD project was a very fast track and unique project it included 5 GMP’s with a 32 month schedule from start of design to completion of construction with a 9 month overlay of design and construction. CSW was successful low bidder on all 5 GMP’s in both Earthwork & Grading and Yard Pipe & Minor Mechanical. All 5 GMP’s were bid at 60%, 90% and Issued for Construction. The 15 MGD had 22,000 LF of pipe from 60” to 1” with 100,000 CYs of structure excavation and 35,000 CYs of structural backfill. Scope of work also included AC paving, curb gutter and sidewalk packages, civil and structural demo, grading, ABC placement, milling placement and SWPPP. The 22 MGD had 25,000 LF pipe from 54” to 1” with 185,000 CYs of structure excavation and 90,000 CYs structural backfill. Additional scope included AC paving, curb gutter and sidewalk packages, civil and structural demo, grading, ABC placement, pavement milling and SWPPP. CSW managed over 235 successful MOPOs during the 15 MGD upgrade. CSW also responded to an emergency failure of a collapsed 24” force main. We worked around the clock to install a 1,300 lf temporary by-pass to allow flows to resume from the Ocotillo WRF to prevent the emergency reservoirs from overflowing. MOPO 10 was a collaborative effort between all stakeholders to give the City of Chandler a permanent by-pass at the Aeration Basins to the Splitter Box that will help on future plant upgrades and allow the plant to accept flow from Intel 4 months ahead of schedule. CSW has completed over 75 MOPO’s on the 22 MGD upgrades and has over a 100 plus more to do.


"Working for CSW, i know i will return to my family safely each day"

"The level of safety withheld on each jobsite is impressive. The amount of recognition CSW and our crews receive from project owners and other subcontractors truly highlights our level of dedication. You can tell that everyone at CSW has bought into the safety program, and that every employee sees how they can benefit. Most importantly, each employee knows how they can make a difference when it comes to daily safety."
