Construction on a new sewer interceptor, a sanitary sewer pipeline that carries wastewater, is set to begin Monday, Jan. 8.
However, that’s dependent on the weather, and if the temperature is above 10 degrees.
Bob Seaman, Archbold village engineer, said the contractor, Vernon Nagel, Inc., Napoleon, has a policy of not working outside when the temperature is below 10 degrees.
From the period of Dec. 26, 2017, to Jan. 1, 2018, the low temperature did not exceed 6 degrees. It has been as low as -5.
Temperatures were as high as 20 degrees.
The National Weather Service forecast for the rest of the week predicts low temperatures ranging from 1 to -7. The highest temperature through Friday is expected to be 14.
When work starts, Seaman said it will begin along Short-Buehrer Road, west of the wastewater treatment plant driveway.
New 24-inch polyvinyl chloride, or PVC pipe, will be installed underground along the south side of Short-Buehrer Road.
Then it will turn north, toward a point on the south side of the Norfolk Southern railroad tracks.
While crews are working along the side of the roadway, Short-Buehrer Road will be closed to through traffic during the day. Local traffic will still be allowed.
When the pipeline turns north, workers will cut a trench through the road surface, and the road will be closed day and night.
Seaman said once work starts, it will be about a week before crews are ready to dig the trench across the road.
As the construction of the sewer interceptor continues north, it will cross Lafayette Street. Crews will cut a trench through the street.
During that time, Lafayette Street will be closed to traffic.
Seaman said he expects that closure to take place in February.
A pathway for part of the sewer project, along the west of the high school property, has already been cut.
Seaman said the owners of the property, Bruce and Joanne Rupp, hired their own contractor to remove the topsoil before pipeline construction started.
There is an existing interceptor in place that carries wastewater from the north side of the tracks directly to the wastewater plant.
Built decades ago, it’s made of concrete pipe, which is deteriorating from hydrogen sulfide gas, commonly found in sanitary sewer lines.
PVC pipe is resistant to hydrogen sulfide.
The new line will be built parallel to the old, which will remain in place as a backup.
A valve will be installed south of the tracks, so the flow can be switched from the old interceptor to the new.
If a repair on the new line is needed, flow can be diverted back to the old pipeline.
Originally estimated to cost over $1 million, the final engineering estimate was over $900,000.
Vernon Nagel, Inc., was the winning bidder at just over $741,000.
Seaman said the company always intended construction of the interceptor as a winter project.
The interceptor will be buried deep underground, at about 17 feet, he said.
Actually, the bottom of the trench may be the warmest place on the construction project.
Seaman added with a trench 17 feet deep, “this is a project where you could get in over your head.”
