Strategy developed for how to quantify stormwater capture statewide

SCCWRP and its partners have developed a six-part strategy that California could use to begin tracking how much stormwater is being captured statewide, part of an ongoing effort to improve water use and reuse practices across drought-prone California.

The strategy, published in April as a SCCWRP technical report, outlines a series of technical approaches that the State Water Resources Control Board could implement to quantify stormwater capture across six distinct components of water resources infrastructure, from stormwater BMPs (best management practices) to inflows at wastewater treatment plants.

The report’s authors examined the complexity, accuracy and level of effort associated with implementing various quantification methods.

The State Water Board intends to use the report as it works to build capacity to track the total volume of stormwater being captured statewide – consistent with a mandate outlined in its Recycled Water Policy.
