AB 803, as introduced, Hueso. Water Recycling Act of 2013.
(1) Existing law requires the State Department of Public Health to establish uniform statewide recycling criteria for each varying type of use of recycled water where the use involves the protection of public health. Existing regulations prescribe various requirements and prohibitions relating to recycled water.
This bill, the Water Recycling Act of 2013, would codify some of these regulations to, among other things, (1) define various terms for the purpose of water recycling criteria, (2) require the use of certain quality recycled water for specified uses with prescribed prohibitions, and (3) modify prohibitions and requirements for dual-plumbed recycled water systems.
(2) Existing law, the California Safe Drinking Water Act, provides for the operation of public water systems, and imposes on the department various responsibilities and duties. Existing law authorizes the department to enact regulations and the department has enacted regulations relating to the protection of public water systems from unapproved water, including recycled water.
This bill would codify some of these regulations to, among other things, (1) define various terms, (2) specify plumping requirements, (3) prescribe certain protection to prevent backflow into the public water supply, and (4) specify when a changeover device may be used.
(3) Existing law requires any person who, without regard to intent or negligence, causes or permits any sewage or other waste, or the effluent of treated sewage or other waste to be discharged in or on any waters of the state, or discharged in or on any waters of the state to immediately notify the local health officer of the director of environmental health of the discharge, as prescribed.
This bill would provide that this notification requirement does not apply to an unauthorized discharge of effluent of treated sewage defined as recycled water, as defined.
(4) Existing law establishes the State Water Resources Control Board and the California regional water quality control boards as the principal state agencies with authority over matters relating to water quality.
This bill would authorize compliance with effluent limitations and any other permit or waste discharge requirements for the release or discharge of advanced treated purified water, as defined, into a conveyance facility at the point where the advanced treated purified water enters the conveyance facility but prior to commingling with any raw water or other water source.
Vote: majority. Appropriation: no. Fiscal committee: yes. State-mandated local program: no.

9or probably will be, discharged in or on any waters of the state, as
10soon as that person has knowledge of the discharge, shall
11immediately notify the local health officer or the director of
12environmental health of the discharge.
