Plant Performance – 2009 The Sturbridge WTP has an average daily design flow capacity of 1.6 million gallons. The Town’s water storage capacity is 2.3 million gallons, which equals 2 ½ days of normal water usage.

In 2009, the Sturbridge WTP effectively treated and supplied an average of 683,000 gallons of water daily. This amounted to a total of over 249 million gallons of water produced (finished water) and pumped into the Town’s distribution system. During spring and fall flushing of the water mains 2.59 million gallons were used. As upgrades continue, the Iron Removal Plant’s performance remains excellent.

To ensure the quality of the Town’s drinking water, the water plant must meet an array of state and federal drinking water quality requirements. These regulations require testing for everything from the aesthetic quality of the water, including color and clarity, to parameters not detectable to taste or vision, such as coliform, lead and copper. All sampling and testing was performed according to all water quality standards set forth by the Federal Safe Drinking Water Act.

Veolia Water ensures the quality of the Town of Sturbridge’s drinking water is consistently high through operating efficiencies such as:

  • Monitoring water characteristics and treatment plant operation through daily influent and effluent water sampling to test chemical dosing and process control for treatment plant optimization

  • Inline pH and Chlorine analysis for constant 24 hour per day monitoring

  • Establishing an efficient filter backwash schedule that includes a weekly high pressure air scrubbing cycle

  • Annual filter inspections and media sampling for quality and performance testing to ensure optimum filter efficiency and effectiveness

  • Maintaining a comprehensive corrosion control program through the addition of phosphate to sequester iron and manganese and to prevent the leaching of lead and copper from the distribution system

  • Sampling and testing weekly at multiple location throughout the Town, to monitor water quality in the distribution system

  • Sampling and testing monthly for total coliform and chlorine residual in the distribution system

  • Pressure logging at key points in the distribution system

  • Use of water hydrant bleeders at location in town with dead-ends to keep water fresh and prevent water form becoming stagnant and stale

  • Semi-annual water hydrant flushing to keep water distribution system clean
