Water conservation: urban water management.

Existing law imposes various water use reduction requirements that apply to urban retail water suppliers and agricultural water suppliers, including a requirement that the state achieve a 20% reduction in urban per capita water use by December 31, 2020. For the purpose of meeting this goal, an urban retail water supplier is required to develop urban water use targets and an interim water use target by July 1, 2011, and to take other related actions. Existing law requires an urban water supplier to prepare and adopt, and update every 5 years, an urban water management plan. Existing law grants a specified extension to an urban retail water supplier for the adoption of an urban water management plan that is due in 2010, to allow use of certain technical methodologies that the Department of Water Resources is required to develop for purposes of those water use reduction provisions. Existing law requires an urban retail water supplier that adopts an urban water management plan in 2010 that does not include those technical methodologies to amend the plan by July 1, 2011, as specified. This bill would grant the extension for adoption of an urban water management plan that is due in 2010 to an urban wholesale water supplier to permit coordination between an urban wholesale water supplier and urban retail water suppliers.
