The improvement project was launched in 2006.

A 2008 Herald story says Wastewater Treatment Plant improvements include renovations of headworks, repair to existing SBR tank, repairs to existing sludge holding tank, construction of a new sludge holding tank, and construction of a sludge cake pump.

Pump stations to be upgraded at Sav-A-Tool, Mollohan site, Industrial Park, Phillips Run and the Shirley Hosey property.
