The Long Beach Water Department has been selected to receive $3 million for its seawater seawater
Water that makes up the oceans and seas. Seawater is a complex mixture of 96.5% water, 2.5% salts, and small amounts of other substances. Much of the world's magnesium is recovered from seawater, as are large quantities of bromine. desalination research and development project, which includes design, construction and subsequent research of its Under Ocean Floor Intake and Discharge Demonstration System, the first of its kind in the world, focused on demonstrating an alternative to traditional open ocean intake and discharge practices. Local agencies, academic and research institutions, and water agencies are able to use these funds for construction, pilot and demonstration projects, research and development, and feasibility studies to increase new water supplies utilizing desalination.
Funding for desalination projects is available through Proposition 50, the Water Quality, Supply and Safe Drinking Water drinking water
supply of water available to animals for drinking supplied via nipples, in troughs, dams, ponds and larger natural water sources; an insufficient supply leads to dehydration; it can be the source of infection, e.g. leptospirosis, salmonellosis, or of poisoning, e.g. Projects, Coastal Wetlands Purchase and Protection Act passed by California voters in 2002. Proposition 50 authorized the sale of $3.4 billion in general obligation bonds for a variety of water projects including coastal protection, the CALFED Bay Delta Program and integrated regional water management, among others. In January 2005, DWR received 42 eligible applications requesting $71.3 million in desalination funding. The DWR is recommending that the available $25 million under the current desalination grant cycle be used to fund 25 projects. Approximately $11.5 million of the available funds will support seawater desalination related projects and $13.5 million will support brackish brack·ish

"I believe these funding recommendations not only validate the real potential for seawater desalination along the coast of California, but also the need for a meticulous approach to seawater desalination research and development," stated Kevin L. Wattier, General Manager of the Long Beach Water Department. "This money will be spent on optimizing both the energy efficiency and environmental issues currently hindering implementation of full-scale seawater desalination."
High operating costs operating costs npl → gastos mpl operacionales , due primarily to high rates of power consumption, and environmental issues related to open-ocean intake and discharge have rendered seawater desalination cost/environmentally prohibitive. Although significant advancements in technology have extended membrane life while lowering energy requirements, overall energy consumption remains extremely high due to the very high-pressure requirements of reverse osmosis reverse osmosis

Using a small 9,000 gallon-per-day pilot-scale desalter, the Long Beach Water Department has reduced the overall energy requirement (by 20 to 30 percent) of seawater desalination using a relatively low-pressure two staged nano-filtration process, developed by Long Beach Water engineers, known as the "Long Beach Method."
This unique process is now being tested on a larger scale. With funding assistance from the United State Bureau of Reclamation, the Los Angeles Department of Water & Power and now, the State of California, Long Beach Water will conduct research at a 300,000 gallon-per-day prototype-scale desalter incorporating the two-stage nano-filtration process. Construction of this facility will be completed in August 2005. This larger facility is needed to verify the energy savings when employing full-scale membranes and energy recovery units, among other things. The goal is to verify energy savings of the two-stage nano-filtration process and to optimize the process so that it can be duplicated.
Together with its funding partners, Long Beach Water is also undertaking design and construction of an Under Ocean Floor Intake and Discharge Demonstration System, the first of its kind in the world, that will seek to demonstrate that viable, environmentally responsive intake and discharge systems can be developed along the coast of California.
The Long Beach Seawater Desalination Research and Development Project is consistent with the findings and recommendations for seawater desalination of the United States Bureau of Reclamation, California Resources Agency The California Resources Agency is a top-level executive branch agency in the state government of California.

The Long Beach Water Department's pursuit of seawater desalination is also an integral component of the Southern California region's long-term water supply plan, included in the Integrated Resource Plan (IRP See Interest rate parity line. ) of the Metropolitan Water District of Southern California.
