The City of Danville’s Wastewater Treatment Plant (WWTP) was originally constructed in 1981, with expansion and renovation in 1998. No major improvements have been made since 1998. Many of the plant’s treatment components are nearing the end of their useful life.
The WWTP has a permitted capacity of 6.5 million gallons per day (MGD). Average daily flows to the WWTP are approximately 5.8 MGD. The WWTP is located at 1970 Stanford Road, and discharges to Clarks Run.
Improvements to the WWTP have been planned and are being implemented as a two-phase project. Phase I will address immediate needs at the WWTP, with Phase 2 adding process capacity to expand the WWTP. The Phase 1 improvements will address process needs, plant modernization, and employee facilities to improve overall plant operations. The Phase 1 improvements will provide the infrastructure at the WWTP to allow expansion of the facility. Phase 2 will expand the facility by adding a new Oxidation Ditch and two new clarifiers to increase the plant’s capacity to 9.0 MGD. Construction of the clarifiers will require demolition of the old Operations/Control building.
Phase 1 has an anticipated completion date of February 2023. Design of Phase 2 will continue while Phase 1 is under construction. Anticipated design completion and letting of Phase 2 upon closeout of Phase 1.
