Water and wastewater utilities operate some of the most energy-intensive, process-critical facilities in the public sector. As operating costs rise, infrastructure ages, and regulatory expectations increase, utilities must keep treatment systems running continuously while maintaining affordability, compliance, and long-term performance.
OPTERRA partners with utilities to modernize treatment facilities through process-driven, performance-based solutions that reduce operating costs, strengthen compliance, and support reliable, uninterrupted operations, without increasing ratepayer burden.

Biogas
Biogas utilization enables wastewater utilities to convert digester gas into on-site energy or renewable natural gas, reducing operating costs and dependence on the grid while strengthening long-term stability. By capturing and treating biogas from biosolids processes, utilities improve energy resilience and create new value from existing assets without increasing ratepayer burden.
We partner with utility leaders to evaluate digester performance and deliver turnkey biogas systems with guaranteed outcomes. OPTERRA designs, owns, operates, and maintains biogas assets, transferring risk away from plant staff while supporting reliable, compliant, always-on wastewater operations.
Meeting sustainability goals with comprehensive energy, infrastructure, and process improvements.
