Fabrication QA Water Treatment Representative Projects

The Twin Oaks Valley Water Treatment Pant DBO is part of San Diego County Water Authorities $3.2 Billion dollar Capitol Improvement Projects currently underway. This project will produce up to 100 MGD of treated water per day, which is enough to meet the needs of the approximately 220,000 residents each year. The plant will use submerged membrane technology, separating water molecules from contaminates producing high quality treated water. The project is a design build and operate DBO project managed by CH2MHILL who will operate the facility for 15 years. The work being performed consists of the construction of new buildings and water treatment structures, installation of fabricated steel pipe and fittings, and related systems, gates and valves, and other appurtenances.
