Regional Water Recycling Plant No. 5 Upgrade and Expansion

open for bidding

Upgrade and expansion of its Regional Water Recycling Plant No. 5 in Chino. The expansion will increase liquid treatment to 30 million gallons per day, from its current 16.3 mgd, using membrane bioreactor and ultraviolet disinfection processes and will expand the biosolids management system to 40 mgd, including thickening, anaerobic digestion and dewatering, and potential food waste treatment. It also includes cogeneration upgrades as well as ancillary support facilities that involve the replacement, relocation and construction of new offsite facilities such as sewage lift stations, force mains, brine lines and recycled water conveyance pipelines. The increased biosolids treatment capacity at RP-5 will replace Regional Water Recycling Plant 2, allowing that facility to be decommissioned.
