Bill > S591

This bill establishes comprehensive regulations for greywater recycling in Massachusetts, focusing on creating guidelines for water conservation and reuse in residential and multi-family buildings. The legislation defines greywater as wastewater from sources like showers, sinks, and washing machines (excluding toilet or food waste water), and creates two tiers of greywater systems: Tier 1 for single-family residences with flows up to 400 gallons per day, and Tier 2 for larger systems processing between 400-3,000 gallons daily. The bill mandates that greywater systems must be connected to public sewer or on-site sewage systems, with specific requirements for storage, labeling, and application, such as using purple-colored pipes for identification, avoiding direct human contact, and preventing runoff. Local boards of health will be responsible for implementing and enforcing these regulations, with the ability to establish permits and fees. Importantly, the bill requires all new multi-family construction projects and significant renovations over 10,000 square feet to incorporate greywater recycling systems, with the regulations set to take effect on January 1, 2026. The primary goals are to encourage water conservation, protect public health, increase water supply efficiency, and provide cost-effective water reuse options for building owners.
