Water Treatment Plant

About the Plant

The Water Treatment Plant for the City of Phillipsburg was put into service in 1989 and provides potable water to residents and industries in the Phillipsburg Community.

The plant is unique in that it utilizes a ClariCone™ Clarification system with lime-softening to soften and remove solids from the raw water. The plant utilizes an aeration tower to help remove solids, prior to entering the ClariCone™, then water is recarbonated with CO2 to adjust the pH levels, disinfected with chlorine, fluoride is added, and finally filtered to help remove turbidity, cloudiness, taste and odor.


Production capabilities at the plant are around 1,200 gallons per minute, or 1.73 million gallons per day. Typically, the plant operates at a production rate of 900 gallons per minute for an average of 14 hours per day.


Water plant operators are on staff 24 hours a day, 7 days a week, and perform all maintenance of the facility. They also conduct all testing and sampling at the plant and throughout the distribution system to ensure compliance with all state and federal drinking water regulations.
