Poughkeepsie’s Water Treatment Facility is the first in filtration an advanced drinking water treatment facility that treats water taken from the Hudson River and supplies the water delivered to City of Poughkeepsie and the Town of Poughkeepsie customers.
Raw Water Intakes
Raw water is pumped when needed from the Hudson River through the Low Lift Pump Station, and is pump up into the Main Treatment Plant and maintain flows through all stages prior to filtration.
Pre-treatment is used to describe the treatment that occurs prior to filtration, including Coagulation, Flocculation and Sedimentation Basins. Water exiting the Sedimentation Basin is called clarified water.
Ozone is dosed to the filtered water to achieve powerful disinfection. Residual ozone is then quenched by a reducing agent.
Granular Activated Carbon
The ozonated water gets pumped to Granular Activated Carbon (GAC) contactors where a variety of organic and chemical compounds are removed. The water is dosed with chlorine to ensure a residual concentration remains throughout the entire distribution system.
Finished water is collected in the 5 million gallon College hills reservoir. College Hills deliver water delivery to the Authority’s distribution system where a network of pipes, pump stations, and storage tanks deliver high quality water to the customers, while also providing fire protection for the surrounding communities.
Dual transmission mains and a generator at the treatment plant, along with generators at the well houses and booster stations, provide further assurance to customers of a constant water supply.
