On July 19, Erwin Utilities’ Wastewater Treatment Plant received an Operational Excellence Award from the Water Environment Association, Kentucky/Tennessee Section at the annual Water Professionals Conference held in Knoxville.
This award is given to utilities or municipalities whose wastewater treatment plant has one or less permit excursion during a calendar year.
According to a press release from the company, Erwin Utilities is nearing completion of approximately $2.7 million in improvements at the wastewater treatment plant and within the wastewater collection system. Improvements at the wastewater treatment plant include new headworks, new influent pumps and variable frequency drives, new sludge pumps, new piping and flow regime changes to the rotating biological contactors (RBC’s), new clarifier effluent launder covers, and improvements to the disinfection system. Work within the collection system has consisted of lining aging clay sewer pipes with new cured-in-place pipe and rehabilitating brick manholes.
The collection system work has effectively reduced groundwater infiltration and stormwater inflow into the sanitary sewer, Erwin Utilities also reported. All of the recent upgrades have improved the efficiency and performance of the wastewater treatment plant, which supports Erwin Utilities’ mission to deliver safe, reliable, and efficient services to the community and every customer every day.
Erwin Utilities is proud of this award as it recognizes the progress that has been made in improving our community’s wastewater infrastructure, according to a press release from the company.
