Bill > H774

This bill aims to regulate greywater recycling systems in the Commonwealth, defining greywater as wastewater from showers, bathtubs, hand-washing sinks, and clothes washers, excluding water from toilets or that has contacted human excreta. It establishes guidelines for reusing greywater for toilet flushing and subsurface irrigation, encouraging water conservation and cost savings, and mandates greywater recycling in new multifamily construction projects. The bill outlines two tiers of greywater systems: Tier 1 for single-family residences with a maximum daily flow of 400 gallons, and Tier 2 for larger residential or non-residential buildings processing between 400 and 3,000 gallons daily, with Tier 2 systems requiring a permit and further guidelines from state departments. Local boards of health are responsible for implementing and enforcing these regulations, with the authority to establish permit fees, and the bill specifies various requirements for system construction, storage, identification, and application to ensure public health and environmental protection, while also clarifying that greywater use does not replace the need for approved sewage disposal systems.
