Wastewater Treatment Plant

The facility is a secondary wastewater treatment plant with a design flow of 1.5 million gallon per day (mgd). Due to the closure of the Wright Mill in 2006, which was the system’s largest contributor at the time, and other industrial sources closing, there is excess capacity in the system and plant to accommodate additional flow.  As of now, the plant receives 100% domestic wastewater.  The wastewater treatment plant supports a healthy aquatic environment by discharging treated effluent to the Quaboag River in the Chicopee River Basin, a tributary of the Connecticut River that ultimately flows to Long Island Sound.  A healthy river ecosystem plays a direct role in promoting and protecting local biodiversity in the region

• Current Plant Start Up: 1989
• Population Served: Approx 3,750
• Design Flow: 1.5 MGD; Daily Average .225 MGD
• Facility Grade: 5

Sewer System

The Town of Warren has approximately 18 miles of sanitary sewer.  That includes two siphons, two pump stations with associated force mains, and a gravity mainline.  Parts of the sewer system date back to 1964 which makes a substantial portion over 60 years old.  Improvements were made in 1984 which are now over 40 years old.  Sewer mains range from 6 to 12 inches in diameter, with nearly 75% measuring 8 inches. Over half of the system is asbestos cement (AC), while polyvinyl chloride (PVC) and vitrified clay (VC) account for about 20% and 15%, respectively; the remainder is ductile iron (DI). Pipe data may be updated as mapping progresses. Overall, the collector sewers are in good condition but require ongoing maintenance.
