Water Filtration Plant Clearwells Replacement Project
The City of Oshkosh is completing a significant infrastructure project called The Water Filtration Plant Clearwells Replacement Project.
The clearwells are buried tanks used to store treated drinking water. The tanks are over 100 years old and do not meet today's safe drinking water regulations. Current standards prohibit the storage and associated buried gravity piping and pump stations in direct contact with groundwater. The Clearwells Replacement Project is needed to replace the clearwells with new storage reservoirs that comply with current regulations.
The project is the construction of two new reservoirs totaling 2 million gallons to store drinking water and a new pump station at the Water Filtration Plant site to deliver water to the City.
The new reservoirs will have improved water quality monitoring capabilities and modern security features to ensure the safety and reliability of the city's water supply. The project also includes the modifications to the chlorine contact basin and various other upgrades to the water filtration plant.
