An Act relative to greywater recycling

This bill amends Massachusetts plumbing codes to establish guidelines for greywater recycling systems in multi-family buildings that use less than 3,000 gallons of water per day. It defines greywater as wastewater from sinks, showers, and washing machines, explicitly excluding toilet waste and hazardous substances, and allows its reuse for toilet flushing and subsurface irrigation. Local boards of health are authorized to implement and enforce these regulations, including the ability to charge fees for permits, while ensuring that greywater systems do not replace required sewer connections. The legislation aims to encourage water conservation and cost savings without altering existing requirements for blackwater disposal or public sewer connections.
