A joint venture between McCarthy Building Companies Inc. and Sundt Construction Inc. was recently selected as general contractor for the $120 million Ocotillo Water Reclamation Facility (OWRF) Expansion and Process Improvement Projects for the City of Chandler. The project includes $100 million in new construction and $20 million in upgrades to the existing plant.
Located near the southwest corner of Queen Creek and Price roads in Chandler, the OWRF expansion project will include upgrades to the existing 10-mgd wastewater treatment plant and the construction of an expansion facility that will be built for a future capacity of 30-mgd. The new facility will utilize membrane bioreactor technology (MBR), which is the combination of activated sludge treatment together with a separation of the biological sludge by micro- or ultra-filtration membranes. The technology allows for a smaller footprint and reduced sludge production.
