The Santa Barbara desalination plant addresses the growing water demands that resulted from severe drought in CA.
The original plant was constructed in 1991 and deactivated in 1992. Twenty-three years later, the city decided to reactivate to plant after a long-term standby mode followed by persistent drought.
A significant engineering, new design and updated intake structure, brine discharge system, and other modifications were implemented in the refit process to contribute significantly to the city’s water needs.
- Capacity: 10,560 m³/day
- Technology: Reverse Osmosis (RO)
- Project Type: Engineering-Procurement-Construction (EPC), Operation & Maintenance (0&M)
- Location: USA
- Footprint: 1.45 acres
- Commissioning date: May 2017
-
Flexible project structure to meet the municipality’s needs
A DBO (Design-Build-Operate) project structure allowed the city of Santa Barbara to maintain ownership of the plant while IDE designed, built and operates the plant to deliver agreed capacity.
-
Lowest desalination water costs
The plant is fully automated and modular in construction, meaning capex and opex were significantly reduced.
-
Proprietary DOHS
Process maintains constantly clean membranes without chemicals and without stopping the RO train.
-
Faster and more economical construction
Prefabrication and preassembly meant construction time and costs were significantly reduced.
-
Highly economical operation
Monitoring and most maintenance takes place directly in the skid, thus further reducing opex.
