AB-968 Urban water use: water efficiency.(2017-2018)



SECTION 1.

 Section 10608 of the Water Code is amended to read:

10608.
 The Legislature finds and declares all of the following:
(a) Water is a public resource that the California Constitution protects against waste and unreasonable use.
(b) Growing population, climate change, and the need to protect and grow California’s economy while protecting and restoring our fish and wildlife habitats make it essential that the state manage its water resources as efficiently as possible.
(c) Diverse regional water supply portfolios will increase water supply reliability and reduce dependence on the Delta.
(d) Reduced water use through long-term water use efficiency and  conservation provides significant energy and environmental benefits, and can help protect water quality, improve streamflows, and reduce greenhouse gas emissions.
(e) The success of state and local water conservation programs to increase efficiency of water use  use efficiency programs  is best determined on the basis of measurable outcomes related to water use or efficiency.
(f) Strengthening local and regional drought resilience is essential to increasing water supply reliability and the sustainable management of the state’s water resources.
(f) (g)  Improvements in technology  technology, infrastructure,  and management practices offer the potential for increasing water efficiency in California over time, providing an essential water management tool to meet the need for water for urban, agricultural, and environmental uses.
(g) (h)  The Governor has called for a 20 percent per capita reduction in urban water use statewide by 2020. implementation of the comprehensive California Water Action Plan. 
(h) (i)  The factors used to formulate long-term  water use efficiency targets can vary significantly from location to location based on factors including weather, climate,  patterns of urban and suburban development, water supplies,  and past efforts to enhance water use efficiency. Therefore, it is necessary to plan for and implement water use efficiency measures at the regional and local level to reflect and best meet the water supply needs of each community and achieve effective water planning and management. 
(i) (j)  Per capita water use is a valid  one  measure of a  an urban  water provider’s supplier’s  efforts to reduce urban  improve  water use efficiency  within its service area. However, per capita water use is less useful for measuring relative water use efficiency between different water providers. Differences in weather, climate,  historical patterns of urban and suburban development, and density of housing in a particular location need to be considered when assessing per capita water use as a measure of efficiency.

(1) Recommendations of appropriate performance measures for commercial, industrial, or institutional water use that shall rely, to the extent appropriate, on the 2013 report to the Legislature by the CII Task Force entitled “Water Use Best Management Practices” and support the economic productivity of California’s commercial, industrial, and institutional sectors.
(2) Appropriate commercial, industrial, and institutional classifications that address significant uses of water and are consistent with the classifications and standards developed by the North American Industry Classification System published by the United States Office of Management and Budget.
(3) Recommendations for appropriate thresholds by which urban water suppliers could require commercial, industrial, and institutional water users to participate in audits and the development of water management plans.
(4) An evaluation of feasability criteria and cost-effectiveness of separating mixed-use meters and equivalent technologies and recommendations on when separating mixed-use meters should not be required.
(c) Using available funds, the department shall provide technical and financial assistance to the task force to enable the completion of the report within the required time frame and to assist water suppliers and water users to comply with any new requirements resulting from implementation of the report recommendations.
(d) (1) A report to be submitted pursuant to subdivision (b) shall be submitted in compliance with Section 9795 of the Government Code.
(2) Pursuant to Section 10231.5 of the Government Code, this section is repealed on January 1, 2024.

 Section 10608.46 is added to the Water Code, to read:

10608.46.
 (a) The department shall reconvene its Urban Stakeholder Committee by April 1, 2018. The committee shall consist of a mix of small, medium, and large urban retail water suppliers from throughout the state, including at least one representative from each hydrologic region. The committee shall also include academic experts, urban wholesale water suppliers, business organizations, as well as representation of combined retail water and wastewater agencies.
(b) By July 1, 2019, the department shall consult with the committee to develop the methodologies required by subdivision (f) of Section 10608.25.
