Measures to Incentivize Graywater Use

Under current law, a board of county commissioners or governing body of a municipality (local government) may authorize the use of graywater within its jurisdiction. Graywater refers to certain types of wastewater that is collected from fixtures before it is treated and put to certain beneficial uses.

The bill authorizes the installation of graywater treatment works in new construction projects and the use of graywater statewide; except that a local government:

• May adopt an ordinance or a resolution prohibiting the installation of graywater treatment works or the use of all graywater or categories of graywater use within its jurisdiction; and
• Shall notify the division of administration in the department of public health and environment of any such local ordinance or resolution adopted and of any local ordinance or resolution adopted that authorizes a use of graywater previously prohibited.

To incentivize the installation of graywater treatment works within a residential building for indoor water reuse, the bill also creates a state income tax credit that allows a taxpayer to claim a credit up to 50% of the cost of such an installation or up to $5,000, whichever amount is less.
