Bill > H922

This bill establishes comprehensive regulations for greywater recycling in Massachusetts, creating two tiers of systems for reusing wastewater from sources like showers, sinks, and washing machines. For Tier 1 systems (serving single-family residences and handling up to 400 gallons per day), the bill allows homeowners to reuse greywater for toilet flushing, gardening, and landscape irrigation without a permit, provided they follow strict guidelines to minimize health risks and environmental contamination. These guidelines include avoiding human contact with the water, ensuring proper drainage, using specific storage and piping requirements, and preventing water pooling or runoff. Tier 2 systems, which serve multi-family and commercial buildings processing between 400 and 3,000 gallons per day, follow similar requirements but require a standard permit. The bill mandates that all new multi-family construction projects over 10,000 square feet must implement greywater recycling systems, with local health boards responsible for implementation and enforcement. The primary goals are to encourage water conservation, reduce water usage, protect public health, and provide cost-effective water reuse options. The regulations will take effect on January 1, 2026, giving municipalities and property owners time to prepare for the new requirements.
