Upgrade of Adjustable Frequency Drives at Waste Water Treatment Plan

This project involves replacing antiquated adjustable frequency drive (AFD) equipment that has reached the end of its service life at the City’s Wastewater Treatment Plant. The current AFD drives, originally installed in 1986, represent very early applications of variable speed control technology. Advancements in AFD electronics since 1986 have resulted in more efficient and reliable equipment with substantially improved power factors and reduced power consumption. Replacement of the selected AFDs would improve the reliability of critical WWTP equipment and reduce overall operating and maintenance costs. Energy efficiency improvement alone pays for the project investment in less than 10.
