FARMINGTON — A Farmington man is suing the town and two local contractors after a broken sewer line and subsequent blockage flooded his home with raw sewage in January and forced him to move out for months.

Joseph Pinkham of 142 Prescott St. said negligence by the town and contractors Bruce A. Manzer Inc. of Anson and Ted Berry Co. Inc. of Livermore resulted in extensive damage to the house and significant costs to make repairs and renovations.

“Mr. Pinkham lived there many years and never had any problems,” his lawyer, Jeffrey Edwards, said. “He certainly doesn’t want to sue the town where he’s lived most of his life, but obviously he has no choice because of the significant harm he’s suffered because of this discharge of raw sewage into his home.”

In late January, the town sewer line next to Pinkham’s property became plugged, causing raw sewage to back up and flood his home, according to the lawsuit filed April 10 at Franklin County Superior Court.

The town hired Bruce A. Manzer Inc. to repair Prescott Stree last summer. During those repairs, Manzer’s equipment crushed the sewer line. Manzer, in turn, hired Ted Berry Co. Inc. to inspect and clear the sewer lines and ensure they would function properly after repairs were made. However, the company missed a blockage in the line, and, therefore, contributed to the damage, according to the lawsuit.

Matthew Timberlake, president of Ted Berry Co., declined to comment.

A local phone number for Manzer Inc. appeared to be out of service.

Edwards said the company’s assets were sold in February to Pike Industries, an asphalt and aggregate materials producer based in New Hampshire, although that company did not assume any of Manzer’s liabilities.

The lawsuit said the town was also at fault for not ensuring the roadwork was done properly and for failing to act quickly to turn the sewer off when the break occurred.

The house has been uninhabitable since Jan. 23 and probably will have to be demolished, according to Edwards.

Edwards said it is likely the damages will exceed $500,000.

The town has contacted its insurance company to handle the case, Farmington Town Manager Richard Davis said.

“They’ve assigned an attorney, who has said that thus far the town is not liable,” Davis said.
