An act to amend Section 6236 of the Public Resources Code, relating to public lands. add Sections 18940.7 and 18940.8 to the Health and Safety Code, and to amend Sections 13558 and 13558.1 of the Water Code, relating to building standards.
LEGISLATIVE COUNSEL'S DIGEST
AB 836, as amended, Gabriel.
Public lands: Sea Grant research projects. California Building Standards Commission: recycled water: nonpotable water systems.
(1) 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 commission to conduct research to assist in the development of mandatory green building standards for the installation of recycled water systems for newly constructed commercial and public buildings, in consultation with the State Water Resources Control Board and other interested parties.
This bill would require, on or before January 1, 2023, the commission to adopt mandatory building standards requiring that a newly
constructed nonresidential building be constructed with dual plumbing to allow the use of recycled water for all applicable nonpotable water demands, as defined, if that building is located within an existing or planned recycled water service area, as specified.
This bill would require, on or before January 1, 2023, the commission to adopt mandatory building standards requiring that a newly constructed nonresidential building with a total gross floor area of 100,000 square feet or more be constructed with dual plumbing to allow the use of nonpotable water sources for all applicable nonpotable water demands and provide for the collection, onsite treatment, and reuse of available onsite rainwater, graywater, and foundation drainage. The bill would establish exemptions to these requirements, including waiver by the board on a project-by-project basis if the board finds that strict compliance would have a significant adverse impact on public health, downstream water
rights, water quality, operation of a sewer collection or treatment system, or plant life, fish, or wildlife.
(2) Existing law requires the State Water Resources Control Board 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 law requires the board, in consultation with the California Building Standards Commission and the Department of Housing and Community Development, to adopt regulations for risk-based water quality standards for the onsite treatment and reuse of nonpotable water, as provided. Existing law requires a local jurisdiction that elects to establish a program for onsite treated nonpotable water systems to, among other things, adopt, through ordinance, a local program that includes the risk-based water quality standards established by the board. Existing law prohibits the board from administering a local jurisdiction’s
program in place of a local jurisdiction that is unable to effectively implement its program while protecting public health or that decides to terminate its program.
This bill would delete that prohibition. The bill would require the board, on or before January 1, 2024, to establish a program for large onsite treated nonpotable water systems, as defined, for local jurisdictions that do not have a local program for onsite treated nonpotable water systems. The bill would authorize the board to establish a reasonable schedule of fees for reimbursement of its costs of establishing and operating the program.
Existing law requires an amount specified in the annual Budget Act to be available for distribution for public and private higher education for projects under the National Sea Grant College and Program Act, as provided. Existing law requires Sea Grant research projects selected for the state support to have a clearly defined benefit to the people of the State of California.
This bill would make a nonsubstantive change to the above law relating to the selection of the Sea Grant research projects.
Digest Key
Vote: MAJORITY Appropriation: NO Fiscal Committee:Bill Text
The people of the State of California do enact as follows:
SECTION 1.
The Legislature finds and declares all of the following:(a) The California Constitution requires that the water resources of the state be put to beneficial use to the fullest extent of which they are capable and that the waste, unreasonable use, or unreasonable method of use of water be prevented.
(b) Severe drought conditions have increased in frequency over the last decade
resulting in California’s water supplies falling to alarmingly low levels during multiple years.
(c) Based on the projected impact of climate change on California’s snowpack, extremely dry conditions and drought similar to those experienced in 2012 to 2016, inclusive, will likely become more common and occur more regularly in the future. Higher temperatures mean less snowpack, which is the state’s largest water reservoir. Scientists project a loss of at least 25 percent of the snowpack in the Sierra Nevada Mountains by 2050. The Colorado River Basin, which provides drinking water to southern California, has experienced prolonged drought.
(d) Water reuse is one of the most efficient and cost-effective ways to improve drought resilience in California communities. Currently, most buildings use potable water to supply the nonpotable water demands from toilet and urinal flushing, floor
trap priming, cooling towers, and air-conditioning devices. Dual plumbing of buildings allows those nonpotable water demands to be met by nonpotable water sources such as recycled water or onsite-treated graywater, rainwater and foundation drainage.
(e) The State Water Resources Control Board has established goals of recycling 1,500,000 acre-feet of wastewater by 2020 and 2,500,000 acre-feet of wastewater by 2030, however, California is not on track to meet those goals and very little recycled water has been made available to replace nonpotable water use in buildings.
(f) Onsite treatment and reuse of available onsite rainwater, graywater, and foundation drainage in buildings provides a proven avenue for reducing the use of potable water in nonpotable water building applications when recycled water is not available for those applications.
SEC. 2.
Section 18940.7 is added to the Health and Safety Code, to read:18940.7.
(a) On or before January 1, 2023, the commission shall adopt mandatory building standards requiring that a newly constructed nonresidential building shall be constructed with dual plumbing to allow the use of recycled water for all applicable nonpotable water demands if that building is located within either of the following:(1) A recycled water service area that provides recycled water for nonpotable water use in nonresidential buildings.
(2) A planned service area for the provision of recycled water for nonpotable water use in nonresidential buildings for which a specific implementation timeline of 10 or fewer years has been identified by the recycled water provider.
(b) For purposes of this section, “all applicable nonpotable water demands” includes toilet and urinal flushing, floor trap priming, cooling towers, and air-conditioning devices.
SEC. 3.
Section 18940.8 is added to the Health and Safety Code, to read:18940.8.
(a) On or before January 1, 2023, the commission shall adopt mandatory building standards requiring that a newly constructed nonresidential building with a total gross floor area of 100,000 square feet or more to comply with both of the following:(1) Be constructed with dual plumbing to allow the use of nonpotable water sources for all applicable nonpotable water demands.
(2) Provide for the collection, onsite treatment and reuse of available onsite rainwater, graywater, and foundation drainage.
(b) A mandatory standard adopted pursuant to subdivision (a) may be waived, modified, or amended by order of the State
Water Resources Control Board on a project-by-project basis if the board finds that strict compliance would have a significant adverse impact on public health, downstream water rights, water quality, operation of a sewer collection or treatment system, or plant life, fish or wildlife.
(c) The requirements adopted pursuant to subdivision (a) shall not apply to the following buildings:
(1) A building with an intended purpose that would produce less than 1,500 gallons of graywater per day.
(2) A building that is located within a local jurisdiction that does not have a program for onsite treated nonpotable water systems that meets the requirements of Section 13558 of the Water Code and the State Water Resources Control Board has not established an applicable program for onsite treated nonpotable water systems pursuant
to Section 13558 of the Water Code.
(3) A building constructed with dual plumbing to allow the use of recycled water for all applicable nonpotable water demands if the building is located within a recycled water service area that provides recycled water for nonpotable water use in buildings or within a planned service area for the provision of recycled water for nonpotable water use in buildings for which a specific implementation timeline has been identified by the recycled water provider.
(d) For the purposes of this section, all applicable nonpotable water demands shall include toilet and urinal flushing, floor trap priming, cooling towers, and air-conditioning devices.
SEC. 4.
Section 13558 of the Water Code is amended to read:13558.
(a) On or before December 1, 2022, the state board, in consultation with the California Building Standards Commission and the Department of Housing and Community Development, shall adopt regulations for risk-based water quality standards for the onsite treatment and reuse of nonpotable water for nonpotable end uses in multifamily residential, commercial, and mixed-use buildings.
