The Metropolitan Water District of Southern California is expanding its effort to learn more about the water supply potential of local stormwater capture with a new $7.5 million pilot program approved today by its board of directors. By funding construction of new stormwater projects and installation of monitoring equipment on existing ones, the program will gather data on the amount of water produced by projects that capture local rainfall and stormwater runoff and use it to recharge groundwater basins in the region.
