Concrete Pour for Tanks

Two large equalization tanks are being constructed at Orange County Sanitation District’s Plant No. 2. The tanks will hold a combined 6 million gallons of water and be 30 feet high.

Over the next 6-9 months there will be weekly concrete pours to from the two tanks. Approximately 50 trucks per week will enter off of Brookhurst Street.

About the Groundwater Replenishment System

The Groundwater Replenishment System (GWRS) is a collaboration between OCSD and the Orange County Water District (OCWD). It is the world’s largest water purification system for indirect potable reuse. The system takes highly treated wastewater from OCSD that would have otherwise discharged into the ocean and purifies it using a three-step advanced treatment process. The result is high quality water that meets or exceeds all state and federal drinking water standards.

The Groundwater Replenishment System (GWRS) Final Expansion Project will maximize water reuse, reducing the amount of treated wastewater discharged through the ocean outfall. The project will increase treatment capacity from 100 to 130 million gallons per day, enough water for 1 million people! The final phase of the project is under construction and expected to completed in 2023.
