Biogas: Harnessing Energy from Wastewater
Along with clean water, a water resource recovery facility can produce clean, renewable energy. Resource Renew’s Combined Heat and Power energy project uses biogas, a methane-rich byproduct of the wastewater treatment process to create electricity and heat.
Three engine generators were installed in 2024 and operational by 2025 to produce electricity from the methane-rich “biogas” created during the wastewater treatment process. The electricity and recovered heat provides energy to the water resource recovery facility–helping to control costs and increase the resiliency of wastewater treatment operations. This project will allow us to produce about half the electricity needed to power the entire regional wastewater treatment plant.
There are also plans to reclaim additional wastes to increase biogas production. Investing $24.9 million over 5 years, we can cut electricity purchases in half or more—moving us toward the goal of energy neutrality.
