Case Study - The Challenge: Improving Sewage Pump System Performance

You are here

This case study looks at how Trumbull, Connecticut increased the energy and operating efficiency of its Reservoir Avenue sewage pump station. With the help of ITT Flygt Corporation, the town altered the existing pump system by adding a smaller pump and modifying the system control scheme. The changes reduced annual electricity consumption by almost 44 percent, or nearly 31,900 kWh, saving more than $2,600 per year. The $12,000 project had a simple payback of 4.6 years.
