10-Year Infrastructure Master Plan
Capital Improvement Projects

The Board of Directors of South Coast Water District approved the District’s 10-Year Infrastructure Master Plan in 2009. The Master Plan covers the District’s:

• Potable Water Supply and Distribution System
• Wastewater Collection Treatment System
• Recycled Water Supply and Distribution System

Long-term water supply plan. A critical section of the Master Plan addresses the District’s long-term plan toward "water independence." Currently, the District is primarily reliant on imported water from Northern California and the Colorado River for its drinking water supply. These water supplies are limited due to drought, population growth and pumping restrictions. They are not expected to increase, but rather decrease over time. The District’s 10-Year Plan in this area is:

• 2009: 10% groundwater / 10% recycled water / 80% imported
• 2012: 20% groundwater / 10% recycled water / 70% imported
• 2019: 20% groundwater / 15% recycled water / 30% ocean desalination / 35% imported
