The Role of Onsite Water Systems in Advancing Water Resilience in Silicon Valley

Overview

California’s Silicon Valley faces a host of water challenges. The region’s water and wastewater infrastructure are aging, and in some cases are nearing the end of useful life. Continued growth and development are putting additional strains on the region, and climate change is adding to that burden through sea level rise, more intense storms, and more severe droughts. These challenges present risks but also an opportunity to rethink the design, configuration, and operation of water and wastewater systems.

This report examines the opportunity for corporate investments in onsite non-potable water systems in Silicon Valley. These systems capture and treat water sources generated from within or surrounding a building, such as wastewater or stormwater, and then reuse the treated water onsite or locally for non-drinking purposes, such as toilet flushing, clothes washing, and irrigation. The report finds that these distributed systems can work effectively with centralized water systems to foster resilient communities. This is best done by deliberately siting and integrating onsite water systems into the broader water network. The authors provide a set of recommendations to ensure effective siting and integration of onsite water systems.
