Wastewater Treatment Plant Tours

Due to extensive construction underway at our treatment plants, including the Westside Enhanced Recycled Water Recycling Facility and $2 billion being invested in our Southeast Treatment Plant upgrades, our public, school, and group tours at both the Oceanside and Southeast Treatment Plants are on hold to ensure public and worker safety. This work is helping us ensure our aging sewer system can continue to protect public health and the environment now and for generations to come.
