Description: Among the key findings of the 2002 Water Recycling Task Force was the need to address the dual-plumbing of buildings to flush toilets and urinals. Among the findings in the White Paper from the Plumbing Code and Cross Connection Control Workgroup: “Portions of three California Codes have been identified as including impediments to recycled water use and are addressed in this white paper. They are the California Plumbing Code (CPC) Section 601.2.2 and 601.2.3 and Appendix J dealing with dual plumbed systems, Title 17 Section 7583 et seq. dealing with cross-connection control, and Title 22 Sections 60313-60616 dealing with recycled water dual plumbed systems. These codes pose problems because of their adoption status in some cases, inconsistencies between codes, and possibly unnecessarily restrictive requirements.” Th

Toggle Image California Desalination Planning Handbook 02/01/2008 (PDF, 1.70 MB)
Description: Desalination is receiving increased attention as a means for addressing the water supply challenges of California. Growing population, much of which is located in semi-arid regions of the state, and various other water demands pose increased pressure on existing water supplies. Much of California’s water supply depends on snow accumulation in the winter, providing spring runoff that fills reservoirs and replenishes often depleted groundwater supplies. But in periods of drought, water supply shortages can be encountered throughout the state, particularly in the central valley and southern portion of the state.

Toggle Image California Strategic Growth Plan: Flood Control, Water Supply & Conveyance (2008) 2008 (PDF, 136 KB)
Description: As a result of the Governor’s emergency declaration for California’s levee system in February 2006 and funding provided by the Legislature in the 2006-07 Budget, key repairs to 33 critical erosion sites protecting Central Valley communities were completed in record time. The state is now advancing funds and working with the federal government to repair 71 additional levee erosion sites damaged in the floods of 2006. An unprecedented effort to evaluate 350 miles of urban levees and 1,250 miles of non-urban levees for hidden defects has begun, and the state is leading a coordinated effort involving federal and local agencies to avoid a major flood disaster in California. California must expand its water management and delivery system, including surface storage, groundwater storage and conveyance facilities. In this phase...
Toggle Image California Strategic Growth Plan: Flood Control, Water Supply & Conveyance 2007 2007 (PDF, 573 KB)
Description: Last year, the Governor and Legislature initiated the first phase of a comprehensive Strategic Growth Plan (SGP) to address California’s critical infrastructure needs over the next 20 years. In November 2006, the voters approved the first installment of that 20-year vision to rebuild California. The infrastructure package included water and flood measures in Propositions 1E and 84. These measures provided $4.9 billion for flood management and approximately $1 billion for integrated regional water management including wastewater recycling, groundwater storage,conservation, and other water management actions. In January 2007, the Administration proposed an additional $5.95 billion to augment the existing funding for the SGP through 2016. These new investments in water management will address population growth, climate change and ...
