Hyperion Water Reclamation Plant

Hyperion Water Reclamation Plant is the City's oldest and largest wastewater treatment facility. The plant has been operating since 1894 with multiple expansions and improvements over the last 100+ years.

Today, leading edge technological innovations capitalize upon the opportunity to recover wastewater bio-resources that are used for energy generation and agricultural applications. In addition, air emission controls and odor management facilities are integrated in all improvements. More of these forward thinking strategies will become realities at Hyperion in the coming years to better protect our coastal environment and serve our communities.
