Wastewater Treatment & Phosphorous Removal
HWC Engineering provided design and construction inspection services for a $2.0 million phosphorus removal project for the 24 MGD wastewater treatment plant in Terre Haute, Indiana.
As a result of new effluent limits imposed on the WWTP by the NPDES permit, HWC also completed a compliance plan to identify the needed facilities. HWC was responsible for the design of the chemical feed system and improvements to the anoxic system for biological phosphorus removal. Work included 30” diameter anoxic piping and tank modifications, as well as the addition of chemical storage tanks, feed pumps, feed piping, and building renovations.
Additionally, HWC provided construction administration assistance, serving as the primary contact with the owner for the State revolving fund to provide project financing.
