Veolia lands SFPUC contract to transform wastewater into decarbonized energy
Veolia, through its Water Technologies & Solutions business unit, has earned a $34 million contract to supply biogas upgrading technology for the San Francisco Public Utilities Commission’s (SFPUC) Southeast Treatment Plant.
Built in 1952, the facility is undergoing a $3 billion modernization that will transform it from a traditional wastewater treatment plant into a state-of-the-art resource recovery center, converting wastewater byproducts into renewable, decarbonized energy for local communities.
Veolia will implement its MemGas™ system to purify raw biogas from the plant’s anaerobic digestion process to biomethane, a pipeline-quality renewable natural gas ready for injection into Pacific Gas & Electric's grid. The project will provide 100% beneficial use of the biogas generated at the Southeast Treatment Plant and at full capacity, will produce enough renewable energy to offset the natural gas needs equivalent to approximately 3,800 homes (68 GWh/yr). The system is expected to be operational by June 2027.
“This project fulfills our commitments for beneficial use of the biogas generated at the Southeast Treatment Plant, supports California’s state goals for in-state production and distribution of renewable natural gas, and aligns with the City’s sustainability objectives," said Daniela Brandao, Senior Project Manager, SFPUC.
“This transformative project showcases how cities can create truly circular systems that not only meet performance criteria but generate clean, renewable energy from what was once considered waste,” added Anne Le Guennec, Senior Executive VP for Worldwide Water Technologies at Veolia.
The Southeast Treatment Plant processes approximately 80% of the city’s combined stormwater and wastewater, treating an average dry weather flow of 45 million gallons (170,300 m3) of wastewater daily. This upgrade will capture the biogas produced during wastewater treatment and upgrade it through state-of-the-art gas conditioning and separation processes.
