Rainwater Harvesting

Rainwater catchment—or "harvesting"—is an ancient practice now enjoying a revival. By diverting, capturing, and storing rainwater for later use, rainwater harvesting can help reduce demand on the treated water supply while also helping to limit erosion and polluted run off that can harm our creeks and the bay.

In 2010, MMWD partnered with the Salmon Protection and Watershed Network (SPAWN) on the 10,000 Rain Gardens Project, a community based rainwater harvesting pilot program. For more information, please visit the rain gardens website. The final report is also now available.
