Potable groundwater supply is a first in district's history
Rowland Water District (RWD) marked a significant first: the first new groundwater source since the district was formed more than 60 years ago. The groundwater supply comes from the Central Basin area of southeast Los Angeles County, and was developed through a partnership with La Habra Heights County Water District, Walnut Valley Water District and Orchard Dale Water District. An interconnection was constructed to allow RWD access to the groundwater supply coming directly from La Habra Heights County Water District.
"This is a major step for Rowland Water District - developing groundwater supplies and reducing our need to purchase imported water," said Ken Deck, general manager of RWD. "We are working to protect our customers from the rising cost of imported potable water, and working with our neighboring water districts to secure this new supply source.”
The interconnection will bring approximately 2000 acre-ft of water into the district annually. The project was more than three years in the making, and it reduces reliance upon imported water by nearly 20%. This unprecedented arrangement for RWD will result in significant savings for its customers in the coming years. Prior to the completion of this project, RWD was 100% dependent on imported water.
It is also an important step in continuing the process of drought mitigation and maintaining water reserves during the ongoing drought crisis. Water reserves in Southern California, thanks to the foresight of districts like RWD, are well prepared despite the lack of rainfall and water restrictions, which have affected northern California.
RWD continues to build strong water reserves and seek out new sources of water for the district. The interconnection from the Central Basin is just part of ongoing work to ensure a safe, reliable water supply for its customers.
