That's a Wrap: 2023 End of the Year Update

AWP Construction Site

2023 marked a tremendous year of growth for the East County Advanced Water Purification Program with construction in full swing throughout the entire calendar year. This end of the year update reflects project milestones through 2023.

The project is made up of five segments referred to as packages. Three of those are in construction while two are in design. So far, $200 million has been spent on construction.

Roughly 105,000 cubic yards of soil was imported for major earthwork activities which have since been completed. In addition, 60 percent of the concrete required for the project has been poured. That equates to an estimated 31,000 cubic yards of concrete poured for the completion of the Visitor’s Center slab, three solids handling facility digesters and six water recycling facility aeration basins. Structural steel installation has begun on the Visitor’s Center building as well.

Major permitting accomplishments include the submission of the Title 22 Engineering Report to the Division of Drinking Water. Also, in June of this year, the Draft Report of Waste Discharge was submitted to the Regional Water Quality Control Board for a National Pollutant Discharge Elimination System Permit.

Approximately 12,650 linear feet of 24-inch steel purified water pipeline has been installed marking 25 percent completion. Roughly 6,500 linear feet of wastewater pipeline has also been installed. Meanwhile, 7,000 linear feet of the initial horizontal directional drilling is complete along the intended route for the 36-inch wastewater force main and the 18 and 8-inch residuals pipeline. 

The two remaining packages of the project that are in design are progressing. The Design-Builder (Orion/GHD) completed site surveying, utility locating and geotechnical investigations to support design efforts on package 4. This portion of the project is a regional brine wastewater pipeline from East Mission Gorge Force Main to the City of San Diego sewer that includes new and rehabbed pipelines. Roughly 30 percent of the drawings and specifications as well as cost estimates have been submitted. 

The JPA Board of Directors awarded the Energy Recovery Project Agreement for Phase 1A of package 5 which includes preliminary design. The draft of the Environmental Document to comply with the California Environmental Quality Act is currently being prepared. 

We’d like to thank the community during this ongoing construction work. We are looking forward to achieving many more accomplishments and milestones in the New Year.
