SCSC was founded in 2002 by a group of Southern California water and wastewater agencies to better manage salinity in our water supplies. SCSC’s member agencies include the Eastern Municipal Water District, Inland Empire Utilities Agency, Irvine Ranch Water District, Metropolitan Water District of Southern California, Orange County Sanitation District, Orange County Water District, San Diego County Water Authority, Sanitation Districts of Los Angeles County, Santa Ana Project Watershed Authority, and West Basin Municipal Water District.
Twelve member agencies formed the Southern California Salinity Coalition in May of 2002 as a non-profit organization in order to address the salinity problems. SAWPA is one of the member agencies of the Coalition. The six primary strategic goals of the organization include State and Federal Advocacy, Salinity Information and Education Program, focus Regional and Watershed Planning on salt balance issues, evaluation of brine management alternatives, develop an inventory of salt-generating sources, and identify research funding priorities.
The Coalition is administered by the National Water Resources Institute. It facilitates discussions with policy makers to view the use of watershed and basin planning as a method to achieve salt balance and develop policy for long-term salinity management. The Coalition encourages the implementation of such policies in the basin planning process, Bulletin 160 updates, regional integrated resources planning, urban water management plans, and permit processes. The Coalition also works closely with the Southern California Regional Water Quality Control Boards, U. S. Environmental Protection Agency Region IX, and local agencies to assist dischargers in meeting their requirements through salt and nutrient management plans that can be implemented in a timely fashion.
