The City of Torrance is taking significant steps to bolster its water security through the expansion of the Torrance Groundwater Desalter System. This initiative aims to reduce the city’s dependence on imported water by treating local brackish groundwater.
Project Overview
The Water Replenishment District (WRD) has approved $146 million for the construction of the Torrance Groundwater Desalter Expansion Project. This development is part of WRD’s Brackish Groundwater Reclamation Program, which focuses on converting brackish groundwater into a sustainable water source for the community. The project is expected to be completed by 2029.
Addressing Seawater Intrusion
Torrance sits atop a 14-square-mile brackish groundwater plume, a remnant of seawater intrusion from the mid-20th century. While measures were taken decades ago to halt further intrusion, the existing plume remained untreated. The expansion project will tap into this brackish aquifer, treating the water through reverse osmosis and disinfection processes before distribution.
Enhancing Local Water Supply
Currently, the desalter meets about 25% of Torrance’s water demand, with the remainder sourced from the Colorado River and Northern California. The expansion aims to nearly double the plant’s production capacity, significantly reducing the city’s reliance on imported water and enhancing resilience against drought conditions.
Community Impact
By investing in local water infrastructure, Torrance is positioning itself as a leader in sustainable water management. The project not only addresses environmental concerns but also ensures a more reliable and cost-effective water supply for residents and businesses.
