WINDSOR — Voters in Windsor approved $2 million in renovations to the town’s wastewater treatment facility. Three-hundred seventy residents voted “yes” and 179 voted “no.”

Town Manager Tom Marsh said the treatment plant is about 20 years old and was in need of a complete overhaul. With the $2 million bond, the town will rebuild the facility’s clarifiers and a digester, the section of the plant that breaks down sewage to generate methane gas.

According to Marsh, taxpayers will see an increase between 3 and 4 percent a year to pay off the bond. Approximately 1,600 sewer customers are responsible for paying the bond, but the entire town voted on the bond question.
