Sewer line project to cost $4.4M

JOHNSTOWN - Engineers for the Gloversville-Johnstown Wastewater Treatment Facility estimate a project to replace manholes and repair parts of the facility's 50-year-old main trunk sewer pipeline between the two cities could cost $4.4 million.

C.T. Male Associates of Johnstown this summer conducted a major evaluation of the concrete underground line using video cameras.

The line runs from Harrison Street in Gloversville to the sewage treatment plant on Union Avenue in Johnstown. Findings were released during a presentation by the engineering firm to the Gloversville-Johnstown Joint Sewer Board on Wednesday night.

"Based on our pipeline inspection, we think we have a real good picture of the trunk sewer line right now," said engineer Chad Kortz, who led the project for C.T. Male.

He said some of the pipeline is in good shape, but some of the pipes are "nearing the end of their useful life."

Two C.T. Male field technicians used archival drawings to conduct inspections of most of the 75 manholes along the trunk line. Video inspections of the trunk sewer pipeline were done by two C.T. Male subcontractors - Precision Environmental of Schenectady and Kenyon Pipeline Services of Queensbury.

Project at a glance

What:?The first major repair project on the Glove Cities' 1960s-era main sewer line.

Where: from Harrison Street in Gloversville to Union Avenue in Johnstown.

Cost: estimated at $4.4 million.

When:?10 projects over the next 15 years.

Kortz said the inspection found debris and grit in the flow channel, cracked pipes and some significant obstructions that restrict sewer flow.

"There is a buildup of material actually attached to the reinforced concrete pipe," he said. "We identified 10 projects that should be looked at over the next number of years."

A report by C.T. Male stated: "Reinforced concrete pipe and manholes are very strong, but also susceptible to root penetration at joints, infiltration and inflow, and corrosion due to harsh liquid and gaseous chemicals."

C.T. Male identified 10 projects involving the cleaning and relining of parts of the 19,750-foot pipeline and the replacing manholes. Half of the projects should be considered to be completed in the next five years, and the other five should be completed in five to 15 years, the engineers say.

The trunk line ranges from 24 inches in diameter to 42 inches diameter. The part of the pipeline installed in 1963 is mostly vitrified clay tile sections with pre-cast concrete manholes. Another section installed between 1968 and 1974 is mostly reinforced concrete pipe with cast-in-place concrete manhole bases, channels and benches and pre-cast concrete riser sections and tops.

Sewer plan consultant George Bevington said the board's committees will now review estimates of work done by C.T. Male and evaluate them for potential future capital projects and how they could be financed. He said Kortz may be invited back to prepare bid documents for high priority work.

"This is a long-term plan for a trunk sewer rehabilitation," Bevington said. "We do need some action to happen eventually."

He said the sewer plant has done some minor cleaning of the sewer line in the past, but this would be the first major infrastructure lining work ever done locally on the main sewer line.
