Package 1 is the largest of the five packages. It includes a water recycling facility to treat 16 million gallons of water per day (MGD), an advanced water purification facility to purify 11.5 MGD (enough for 50,000 households), a solids handling facility, a product water pump station, and a new visitor’s center. Construction started in July 2022. Concrete work is underway on three digesters, aeration basin, primary and secondary clarifiers, deep structures, and pump station wet wells. As of mid-September 2023, approximately 50% of the concrete pour needed for the site was completed. Crews continue construction on the visitor’s center and solids handling facility with underground piping and conduits. The team is expected to receive the Division of Drinking Water (DDW) conditional acceptance letter on the Title 22 Engineering Report in October 2023. The contractors for this $614.6 million package are AECOM of San Diego and Lyles Construction Group of Temecula. Construction is expected to be complete in Fall 2026.

Package 4 is in the design phase and is expected to begin construction in Summer 2024. This package is a collaboration between the East County AWP, JPA, and the City of San Diego. It includes rehabilitation of the existing East Mission Gorge Force Main (EMGFM) that will continue to serve as a wet weather failsafe pipeline which conveys peak wet weather sewer flows to the City of San Diego for treatment. It also includes construction of a new East County Residuals Line (ECRL) to convey brine and centrate from the East County AWP Project around the City of San Diego’s Pure Water Program facilities as a regional solution to residuals management. The contractors for this package are Orion Construction of Vista and GHD of San Diego. The anticipated cost for this package is $100 million. Work is expected to be complete in 2026.

Package 5 includes the construction of an energy recovery system. It’ll produce 3 megawatts of renewable energy generated from digester biogas and organic waste. This will supply up to 60% of Package 1’s electricity. The contractor is Anaergia Technologies of Carlsbad. Construction is slated to begin in 2026. This package is currently in the conceptual project development phase. California Environmental Quality Act (CEQA) approval is expected to follow. This package has an anticipated total cost of $50 million and is expected to be complete in 2028.
