Water Facilities and Treatment
The water treatment facilities utilize state of the art automation and on-line analyzers to monitor and control water quality. In addition, the water treatment staff performs thousands of water tests annually to ensure that the water that leaves the treatment plants meets all federal and state water quality standards.
Pond Street Facility
The Pond Street water treatment facility is a conventional water treatment plant which uses chemical addition, rapid mixing, flocculation, sedimentation and filtration through mixed media filters to treat three groundwater wells for iron, manganese, organic color, and turbidity. The facility was originally built in 1973. It received a major upgrade in 1992 and has had incremental upgrades since 1992.
The Pond Street Water Treatment plant is a conventional treatment plant designed to remove iron, manganese, organic color, and turbidity from the raw water. The raw water quality varies depending on the combination of wells that are being used. Readers of this page will see that the plant effectively and consistently removes iron and color. Manganese is more challenging due to tight tolerances in water chemistry that are often in conflict with the color removal process. The average raw water quality at Pond Street in 2018 has been 0.61 mg/l of manganese, 56 units of color, and 0.89 mg/l of iron. The average finished water quality for the same period has been 0.033 mg/l of manganese, 2 units of color, and 0.012 mg/l of iron. Our treatment goals are less than 0.15 mg/l of iron, less than 8 parts of color, and less that 0.05 mg/l of manganese.
Beal Facility
The Beal water treatment plant is located on Riverside Drive. It is a manganese-greensand treatment facility which removes iron, manganese, and radon from two deep bedrock wells using a combination of chemical addition, air stripping, and manganese-greensand pressure filters. It was built in 1994.
The Beal Water Treatment plant is a manganese-greensand treatment plant designed to remove iron, manganese, and turbidity from the raw water. The raw water quality tends to be quite consistent from day to day. The average raw water quality at Beal in 2018 has been 1.05 mg/l of manganese, 33 units of color, and 3.29 mg/l of iron. The average finished water quality for the same period has been 0.018 mg/l of manganese, 0 units of color, and 0.027 mg/l of iron. Our treatment goals are less than 0.15 mg/l of iron, less than 8 parts of color, and less that 0.05 mg/l of manganese.
Broadway Facility
The Broadway water treatment plant is a manganese-greensand facility which removes iron, manganese, small amounts of organic color from the gravel packed wells of the Hanover Street well field and Broadway well field using a combination of chemical addition and manganese-greensand pressure filters. It was built in 2001.
The Broadway Water Treatment plant is a manganese-greensand treatment plant designed to remove iron, manganese, color and turbidity from the raw water. The raw water quality tends to be quite consistent from day to day. Readers of this page will see that the plant effectively and consistently removes iron, manganese, and color. The average raw water quality at Broadway in 2018 has been 0.46 mg/l of manganese, 39 units of color, and 0.73 mg/l of iron. The average finished water quality for the same period has been 0.0.015 mg/l of manganese, 0 units of color, and 0.024 mg/l of iron. Our treatment goals are less than 0.15 mg/l of iron, less than 8 parts of color, and less that 0.05 mg/l of manganese.
