Alvarado Water Treatment Plant - Historical Landmark

San Diego’s oldest existing water treatment plant received a National Historic Award by the American Water Works Association for its direct and significant contributions to water supply, treatment, distribution and technological development. Engraved on the award is the text: "The Alvarado Water Treatment Plant has been the heart of the City of San Diego’s drinking water system for more than half a century, standing as a monument to faithful public service and a landmark for the City and the surrounding community," which was presented in April to Mark Stone, deputy director for the Water Department.

The Alvarado Water Treatment Plant has been delivering safe and clean water to half a million San Diegans without rest for more than 50 years. Alvarado’s Spanish-Colonial architectural design holds a history unique to San Diego. Although the treatment plant is undergoing massive upgrade and expansion, the Water Department is making sure to preserve the facility’s historical and cultural significance.
