The city of Shelby broke ground on Wednesday to upgrade its wastewater treatment plant. RichlandSource.com reports that the total cost to upgrade the facility is $8.7 million and the project will take about 18 months to complete. The last time an update was done to the facility was back in the late 1980’s and Shelby wastewater treatment plant Superintendent Charlton Brown said their machinery is kind of getting worn out. Mayor Steve Schag said this will give the city a state of the art facility and will allow them to receive waste in a way that is approved by the EPA. The work is being handled by North Bay Construction out of West Lake.
