GWRS Outreach Toolkit

When the Orange County Water District (OCWD, the District) and Orange County Sanitation District (OC San) launched the world’s largest potable reuse project, the Groundwater Replenishment System (GWRS), large-scale community support for water reuse was virtually unheard of. Yet OCWD and OC San faced no organized opposition – an outcome still uncommon today.

As agencies around the world sought OCWD and OC San’s guidance, the districts recognized their role extended beyond project delivery – global acceptance of water reuse benefits all. To address this, OCWD led outreach initiatives and created a scalable, customizable model that allows agencies to choose and apply relevant components, ensuring adaptability across regions, organizations, and project scopes.
