Rainwater harvesting is legal and encouraged in Somerville. Rain barrels are promoted by the city for stormwater reduction, with occasional discount sales offered to residents.
Massachusetts has no state prohibition on collecting rainwater from rooftops, and Somerville actively encourages it as a stormwater management measure. The Somerville Department of Public Works and the Mystic River Watershed Association have historically offered subsidized rain barrel sales. Collected rainwater can be used for irrigation and non-potable outdoor purposes without a permit. Large cisterns or systems connected to indoor plumbing require a plumbing permit and must comply with 248 CMR (state plumbing code) and backflow prevention requirements. Somerville promotes green infrastructure (rain gardens, rain barrels, permeable paving) to reduce combined sewer overflows to the Mystic River. Rain barrels must not create mosquito breeding habitat and should have tight screens.
