Earlier this month it was reported that Oklahoma lawmakers approved the Graywater proposal. This legislation allowed private residents to reuse gray water by creating an exemption for gray water systems under 250 gallons (per day).
House Bill 1575, by state Rep. Scott Martin, defines gray water as untreated household wastewater that has not come in contact with toilet waste or water from a kitchen sink.
Gray water systems that would be exempt would have to:
* provide for overflow into the sewer or on-site wastewater treatment and disposal system;
* include cover for any gray water storage tank to avoid the creation of a habitat for mosquitoes and other insects;
* be located outside of a floodway and five feet above the groundwater table;
* clearly identify gray water pressure piping as a non-potable water conduit;
* be used on site and not run off the property;
* minimize the potential for contact with people or domestic pets;
* minimize standing water and ensure the hydraulic capacity of the soil is not exceeded;
* avoid spraying or discharge into a waterway;
* be in compliance with municipal or county ordinances;
House Bill 1575 passed unanimously and now proceeds to the Senate for consideration.
