SOUTHBOROUGH, Mass. – A 3,800-gallon septic truck rolled over at 325 Turnpike St. in Southborough at about 3:15 p.m. today, spilling raw sewage and causing major delays on Route 9 westbound. The truck was owned by Northborough Septic Service, Inc.
Southborough Firefighter Neil Aspesi estimated that about half of the tank's contents leaked out following the accident. (UPDATE: According to Southborough Health Agent Paul Pisinski, only about 150 gallons were spilled following the accident). He said that workers set up booms to mitigate the spill.
Sgt. James Deluca of the Southborough Police Department said it was unclear if any of the spilled sewage reached the nearby waterways that lead to wetlands.
Aspesi said that the Massachusetts Department of Environmental Protection, the Massachusetts Water Resource Authority and the Massachusetts Department of Transportation were all notified of the incident, as was the Southborough Board of Health.
At about 5 p.m., trucks from Ted's of Fayville, a Southborough-based towing company, helped workers from Northborough Septic Service right the fallen truck. By that time, traffic on Route 9 westbound had improved.
Only the driver was in the truck at the time of the accident, and no injuries have been reported. Police are still investigating the cause of the rollover.
