Ashland Water Treatment Plant Resilience Project
The system is replacing the water treatment plant with a new 7.0 MGD direct filtration plant (with the ability to expand to 9.0 MGD for future demands). The WTP improvements include adding ozone, replacing the sand filter, chlorine feed, and flocculation basin. They will also add solar panels to offset the energy costs. The engineering design is done so this project is only for construction and construction management.
