Sewer job critical stage may be reached in week
The sewer laying crew has had excellent weather conditions during its first week of work, but won’t really need it for about another week, when dewatering operations are expected to start.
A single crew with backhoe by Wednesday had completed the outfall at the river and several hundred feet of discharge pipe.
A delay appeared possible because of disagreement over wording of contracts with property owners, over whose land the pipe must pass, but this was apparently settled on Wednesday afternoon and a second crew expected to be put on the job.
The water table is holding at or below the 47-foot level.
If it does not rise, all the trenches should stay dry without pumping.
At the two pumping stations excavations will have to go below that, lowest elevation being 45 feet.
Holes are to be dug near these locations in a few days and gasoline or diesel pumps used to pull the water at the working site below the 45-foot mark.
It is planned to dewater with electric pumps when the pumping stations are actually under construction, but these test will show what size pumps must be provided.
The contractor will do the work, but the municipality must foot the bill for dewatering.
Only by taking this risk was the council able to get a bid within the amount voted for sewer construction.
Heavy rain or an increase in the height of the river are the main risks as far as dewatering is concerned.
Another worry is the possibility of another snowstorm as any delay now will mean loss of winter work contributions to wages later in the year.
