The East County Advanced Water Purification Project announced yesterday the approval of two agreements authorizing $19.6 million for design and pre-construction work.
About the Project
The $681 million project, led by the ECAWP Joint Powers Authority, will recycle daily wastewater flows from Santee, El Cajon, Lakeside, Winter Gardens and Alpine. The recycled water will then go through an advanced treatment process that includes membrane filtration, reverse osmosis and advanced oxidation to produce purified water.
A 10-mile pipeline will transport the purified water to Helix’s Lake Jennings, where it will mix with imported water stored there. Helix will treat the blended water at the R.M. Levy Water Treatment Plant and distribute it to Helix customers and the other agencies Helix serves.
The project will meet up to 30 percent of East County’s drinking water demands and eliminate the discharge of 15 million gallons per day of treated wastewater into the Pacific Ocean.
The ECAWP Joint Powers Authority includes Padre Dam Municipal Water District, the County of San Diego and the City of El Cajon. Helix will purchase the ECAWP’s purified water. On May 27, Helix’s board directed general manager Carlos Lugo to sign water purchase agreements with the ECAWP JPA.
About Yesterday’s Announcement
The ECAWP JPA approved an agreement with AECOM/Lyles to design, construct and perform transitional operation and maintenance services for a water recycling facility with a 16 million gallons per day treatment capacity, an advanced water purification facility with an 11.5 million gallons per day treatment capacity, a solids handling facility, pump station and visitors center.
The agreement authorizes up to $14.1 million for phase one work, which will provide the JPA with the opportunity to evaluate and price options and value‐engineering (i.e., innovative) ideas, refine the project design, continue to eliminate unknowns, and identify and evaluate project risks.
The JPA also approved an agreement with Orion Construction Corporation to design and construct a 10‐mile pipeline, dechlorination facility and inlet to Lake Jennings. The agreement authorizes up to $5.5 million for similar phase one work on this component of the project.
