Drivers for potable reuse
• Non-potable recycled water
(purple pipe) expansion
insufficient to meet future
needs
• Additional water conservation
efforts insufficient to meet
future needs – need the “wet
stuff”
• Potable reuse identified as
most reliable and cost-effective
option, per the District’s Water
Supply & Infrastructure Master
Plan
