Rainwater harvesting is legal and encouraged in Middlesex County. Massachusetts has no statewide prohibition, and many towns offer rain barrel rebate programs through DPW and MWRA.
Rainwater harvesting for outdoor non-potable use is fully legal in Middlesex County and throughout Massachusetts. There is no statewide restriction on residential rain barrels or cisterns collecting roof runoff for garden and landscape use. The MA Department of Environmental Protection and MWRA actively promote rainwater capture as a stormwater management and water conservation strategy. Many Middlesex communities participate in rain barrel sale or rebate programs, including Cambridge, Somerville, Arlington, Belmont, Lexington, Newton, Waltham, and Watertown, often offering 55-gallon barrels at subsidized prices. Larger cisterns over 1,000 gallons may require Building Department permits and structural review. Potable indoor use (drinking, cooking, bathing) requires state plumbing code compliance under 248 CMR including treatment and backflow prevention, and is rarely approved for residential applications. Gutter diverters and overflow must be designed to prevent foundation damage and comply with local stormwater bylaws.
