Building standards: dark graywater.

The California Building Standards Law provides for the adoption of building standards by state agencies by requiring all state agencies that adopt or propose adoption of any building standard to submit the building standard to the California Building Standards Commission for approval and adoption. Existing law requires the Department of Housing and Community Development to propose the adoption, amendment, or repeal of building standards to the commission relating to hotels, motels, lodging houses, apartment houses, and dwellings, and the buildings and structures accessory thereto, except as specified. Existing law requires the department, at the next triennial building standards rulemaking cycle, to adopt and submit to the commission for approval building standards for the construction, installation, and alteration of graywater systems for indoor and outdoor uses. Existing law excludes wastewater from kitchen sinks and dishwashers from the definition of "graywater." This bill would define "dark graywater" as a specified wastewater that comes from kitchen sinks and dishwashers. This bill would require the department, at the next triennial building standards rulemaking cycle, to develop and submit for approval building standards for the construction, installation, and alteration of dark graywater systems for indoor and outdoor uses.
