SUMMARY:
The Water Supply Master Plan (Master Plan) is Valley Water's strategy for providing a reliable and sustainable water supply in a cost-effective manner. It informs investment decisions by describing the type and level of water supply investments Valley Water is planning to make through 2040. The Master Plan analysis continues to indicate that droughts are our greatest challenge and that demand management, stormwater capture, and water reuse are vital to the long-term sustainability of water supply reliability in the county.
Water recycling makes efficient use of existing supplies and is sustainable and consistent with a "One Water" approach (a roadmap for integrated water resource planning). Water recycling provides local supplies that are not dependent on local, regional, or state hydrology. This resiliency is very important during extended droughts when Valley Water's imported supplies are curtailed and local supplies may be limited. In addition, water recycling projects are broadly supported by stakeholders.
One goal of Valley Water is that 10 percent of the county's water supply portfolio be met through potable and non-potable reuse projects by 2025. In December 2017, the Board of Directors approved the development of up to 24,000 AFY of potable reuse. As such, Valley Water has embarked on developing a comprehensive Countywide Water Reuse Master Plan, which will evaluate a variety of water reuse projects, including expansion of non-potable reuse; indirect potable reuse (e.g., groundwater recharge); and direct potable reuse (both raw water augmentation and treated water augment...
