Treatment, Public Health, and Regulatory Issues Associated with Graywater Reuse

There is a wave of new regulations that has promoted the use of residential graywater in single family homes to save water resources. This new trend towards integrated graywater systems has left some states with questions on overall maintenance and safety of these systems due to many unknowns regarding the water quality of graywater, supplemental graywater treatment systems, and potential for public exposure to graywater reuse. This project collects and integrates this knowledge on water quality, reliability of treatment systems, and regulatory parameters into a comprehensive tool.
