Relative to greywater recycling

Impact

The implications of HB 922 are significant for local governance and environmental management. By mandating greywater recycling in new multifamily buildings, the bill is expected to enhance water conservation efforts, potentially reducing the consumption of potable water and mitigating environmental impacts associated with waste water disposal. Local boards of health are designated to implement these regulations, ensuring compliance across the state. This legislation aims to bolster the state's water supply and contribute to public health by minimizing the release of untreated wastewater into the environment.

Summary

House Bill 922 aims to establish regulations that govern the reuse of greywater in the Commonwealth of Massachusetts. The bill focuses on enabling building owners to recycle greywater for non-potable uses, such as toilet flushing and subsurface irrigation, particularly in new multifamily construction. By setting clear plumbing code regulations, the bill seeks to present cost-effective guidelines that promote the sustainable use of water resources in communities throughout the state. It defines greywater as wastewater from sources such as showers, sinks, and washing machines, while distinguishing it from blackwater, which contains human waste and should not be reused in the same manner.

Contention

A notable point of contention surrounding the bill includes concerns over the safety and practicality of greywater recycling systems. Opponents may argue about the risks of contamination and implications for public health, especially as the bill allows for certain types of greywater to be recycled from household sources, potentially raising concerns about how effectively these systems might be managed and monitored. Additionally, the enforcement and implementation of such regulations could pose challenges for local boards of health, which may have varying capacities and resources to manage newly introduced guidelines.
