Down the Drain: Trimming Energy Waste from a Wastewater Facility without Breaking the Bank
NEWEA 2016 Annual Conference & Exhibit
Recently, the Water Pollution Control Facility in Simsbury, CT upgraded to an extended aeration oxygen ditch for nitrogen removal. The operators then initiated several low cost modifications to reduce energy usage and improve process control.

Recently, the Water Pollution Control Facility in Simsbury, CT upgraded to an extended aeration oxygen ditch for nitrogen removal. The operators then initiated several low cost modifications to reduce energy usage and improve process control. These were mainly done by modifying the plant’s SCADA-based control systems though an ongoing maintenance contract. The plant had potential to achieve deeper energy savings through a larger capital project, but capital was not available to implement the work.
Taking a whole-facility approach, the initial review identified areas with high savings potential across the plant. HVAC controls improvements were proposed to reduce energy used to condition the office areas. The anoxic zone mixers and aerator controls for the oxidation ditch could both be optimized. Finally, a cross-discipline effort was included to improve coordination between the odor control system, HVAC system, and process control systems in the solids handling room. The project also set out to improve both phosphorus and nitrogen removal in the anoxic zone of the oxidation ditch by better controlling anoxic mixer speeds.
After a more detailed screening of the potential energy savings concepts, the aerator control concept was modified so it could be implemented under the SCADA system maintenance contract without new equipment. The balance of the project was developed as a design-build project and submitted to the utility for energy efficiency funding. Because it addressed both HVAC systems and treatment processes at the plant, the project was eligible for an incentive bonus. On-bill financing provided by the local utility allowed the town to sign a contract for less than 10% of the project cost up front to implement the project.Other authorsSee publication -
