LOS ANGELES, CA — AECOM, an infrastructure consulting firm, announces that it has been selected to perform work through an Energy Savings Performance Contract for the Los Angeles County Sanitation Districts’ Joint Water Pollution Control Plant (JWPCP) in Carson, California. The contract includes upgrades to the pure oxygen production process, which can result in more than $1.3 million in energy, water, and maintenance cost savings annually and more than $8 million in avoided capital expenditure.

“We’re honored to partner with the Los Angeles County Sanitation Districts to upgrade its JWPCP facility, leveraging the strength of our technical expertise from designing and constructing many large-scale, multi-phase water projects to help improve service for millions of people across Los Angeles,” said Lara Poloni, AECOM’s President. “This important project reflects our commitment to lead in environmental, social, and governance best practices and make a positive impact on the communities we serve.”

“We are excited to have hired AECOM to complete this important retrofit for our agency. They have the special expertise required to successfully complete this complex project. Performing this work through an Energy Savings Performance Contract gets us a completed project sooner, which will provide savings to our ratepayers sooner,” said Paul Mikulas, Supervising Engineer in the Sanitation Districts’ Wastewater and Solid Waste Design Section.

AECOM’s scope of work includes the replacement of two 150 tons per day backup Cryogenic Oxygen Generation Plants with two Vacuum Pressure Swing Adsorption (VPSA) units, which is critical to the plant’s biological system and the facility meeting effluent requirements. The current Cryogenic Systems require multiple days to startup and achieve the required oxygen purity and production levels, making it imperative that the two backup units operate continuously. The main advantage of the new VPSA units is they will not need to operate continuously.

“The JWPCP is a 400 million gallons per day, activated sludge treatment plant that serves five million residents, businesses, and industries in Los Angeles County. The pure oxygen system is one of the most critical facilities in the treatment plant,” said Annika Moman, Senior Vice President of AECOM’s Design and Consulting Services group’s Energy practice. “The new VPSA units utilize adsorption media to separate oxygen from ambient air, achieving oxygen purity and production levels within a few hours. Thus, these units will not operate continuously, resulting in substantial energy, operation, and maintenance cost savings.”
