Rainwater harvesting with rain barrels or cisterns is legal and encouraged in Lowell. Small residential systems used for irrigation are unregulated, while larger indoor-use systems must comply with the Massachusetts Plumbing Code.
Massachusetts places no restrictions on collecting rainwater from rooftops for outdoor uses such as garden and lawn watering, and Lowell actively supports the practice as a stormwater-management and conservation measure. Homeowners may install rain barrels at downspouts without a permit, and many are available at cost through regional conservation programs. Larger cisterns used for non-potable indoor purposes like toilet flushing or laundry must meet the Massachusetts Plumbing Code 248 CMR 10.00, which requires clear separation from potable supply, backflow prevention, and purple-pipe labeling. Potable use of harvested rainwater is generally not permitted without full treatment and Department of Environmental Protection review. Rain gardens, infiltration trenches, and similar green infrastructure that slow and soak runoff are encouraged under Lowell stormwater ordinances, which implement MS4 permit requirements to reduce pollution in the Merrimack and Concord Rivers.
