LIVERMORE FALLS – A water main and line replacement project on several streets is nearing conclusion.

On Thursday, workers from Pratt & Sons Inc., which is replacing mains for the Livermore Falls Water District and sewer lines for Livermore Falls Sewer Department, which are separate entities, were installing the last of 11 new hydrants in the project on Sewall Street for the Livermore Falls Water District.

It was unclear Thursday if there would be enough money to replace the sewer lines on Sewall Street.

That street was added onto the project after voters OK’d borrowing up to $250,000, which would cost an estimated $362,500 over 20 years with interest, to replace sewer lines in conjunction with the Livermore Falls Water District project.

An official estimate of what it would cost to do the sewer work on Sewall Street was never done, Sewer Department Superintendent Kent Mitchell said Thursday.

Now it looks like it will cost $40,000 to $50,000, he said.

Mitchell said they hadn’t planned on Oak Street work either but the sewer line kept breaking while the water mains were being installed and they decided to replace the sewer lines there.

They had decided to borrow the $250,000 for the sewer project because that’s what could be borrowed, along with some additional revenue received, without causing sewer rates to go up, Mitchell said.

“We tried to spend the money on the worst sewer lines,” Mitchell said.

They will bring figures on that project to discuss at the selectmen’s meeting at 6:30 p.m. Monday, Aug. 6, at the town office.

Livermore Falls Water District Superintendent Doug Burdo said he was pleased the project that began this spring was nearing completion.

“These guys have been a good outfit to work with,” Burdo said, of Pratt & Sons.

About 130 new water services from the main to individual properties were installed, he said.

The district’s $809,000 contract with Pratt & Sons for the project, not including Sewall Street, which was added on, included installing 12-inch mains on Park Street from Shuy Corner at the intersection of Route 17, Burdo said.

All mains installed in the project were made of ductile iron, which prevents the growth of iron build-up, and are expected to last more than 100 years, Burdo said.

Eight-inch mains were installed on Birch and Oaks streets and Highland Avenue, and 4-inch mains were installed on Maple, Walnut, Spruce and Chestnut streets.

After the hydrant is installed, Burdo said, they would go from there to the intersection of Depot and Sewall Street and cut the old water line and cap it, he said. Then for the most part, the project would be completed.

The town’s highway crew and the water district worked together to fully pave several of the streets rather than trench-pave the dug up areas, Burdo said, with the water district giving what it would spend on patch paving to the town.

Burdo said he is hoping they can do the same with Sewall Street.

Selectmen unanimously voted July 16 to take $20,000 from the Sewer Department reserve account to pay for the replacement of the sewer line on Sewall Street, which was before an official estimate was done.

The vote had gone against concerns about reducing the $89,000 sewer reserve account, but would allow the town to obtain the $16,000 needed to pave Sewall Street from the Livermore Falls Water District’s share of paving costs, which is nearly half the $32,500 paving cost.
