Energy Efficiency for Municipal Water and Wastewater Treatment: A Win-Win

For municipalities, upgrading water and wastewater facilities to be energy-efficient offers clear benefits. Not only can it lead to notable cost savings, but it also reduces greenhouse gas emissions, aligning with environmental goals. Cascade Energy has experts to ensure that your municipality can reap these benefits, while maintaining safe and reliable operations to protect health and the environment.

Energy Costs can account for as much as 30% to 40% of the total operating costs of a water or wastewater facility!

Water and wastewater treatment facilities are often among the largest energy consumers for municipalities.

Our Approach

We combine the skills of water/wastewater experts with the abilities of seasoned industrial energy efficiency personnel.

This combination of industry knowledge and efficiency tools has helped us create a highly successful process for identifying specific low/no-cost actionable changes that save energy and money for large and small systems alike.


Water and wastewater systems with good energy savings potential.


Water and wastewater personnel in strategic energy management.


Managers and operators to identify and act on energy-saving opportunities.


And build a strong pipeline of future capital projects.


Savings, projects, results, and data using Energy Sensei software.

Idaho Power

Idaho power wastewater energy efficiency cohort

In 2014, Idaho Power and Cascade collaborated on a cohort-based SEM offering for the utility’s wastewater treatment customers. Wastewater Energy Efficiency Cohort, or WWEEC, was an intensive program involving 11 of the 12 largest municipal wastewater accounts in Idaho Power’s service area. The cohort transformed the opinions of the participating cities on the value their utility can provide.

“Energy Sensei has proven to be a very valuable tool for San Antonio Water System’s (SAWS) energy strategy efforts. By pulling in the appropriate energy and water/wastewater data to develop and illustrate energy consumption models, operators have the unique ability to monitor the effectiveness of energy conservation measures in near real-time. This feedback is critical in engaging staff and verifying project savings.”
