Capture methane gas from wastewater treatment
(Full action name in the CAP)Loading
The Public Utilities Department (PUD) currently captures methane gas from wastewater treatment facilities at Point Loma Wastewater Treatment Plant (PLWTP) and Metro Biosolids Center (MBC) using existing staff and infrastructure. This gas is produced by anaerobic digesters that break down organic material, creating methane as a byproduct. The captured methane is used to power plant equipment, added to the natural gas grid, or flared off if not used.
This is an ongoing action that will continue in future years in service of the CAP goal of achieving 95% capture of methane gas produced from wastewater treatment operations. In the near term, this includes gas pipeline upgrades and biogas compressor replacement.
