Contractor testing potential sites for new sewage treatment plant

This barge and drill rig has been deployed along the waterfront on Corner Brook’s east side to test potential sites for the city’s new sewage treatment plant.

If the cost of a new sewage treatment plant is expected to be in the $85-million range, spending around $30,000 to find the best location might be a good idea.

That’s about how much the City of Corner Brook is spending to conduct geotechnical testing of potential sites for the facility to be built in the coming years.

The contractor, Stantec, has a barge with a drill on it situated in a small cove next to the R.A. Pollett Building in the Humbermouth area of the waterfront.

The machine is drilling holes into the substrate beneath the water to see if it is a suitable site for the plant.

The rig has already looked at other sites along the waterfront and may test more.

This site looks the most promising, said Pender of the area between the offices of the Corner Brook Port Corporation and the former gypsum plant.

Currently, around 85 per cent of the raw sewage dumped into the Humber Arm comes through outfalls situated on either side of the Corner Brook Pulp and Paper mill property.

Pender said the treatment plant has to be somewhere on the waterfront and, preferably, in close proximity to those two main outfalls.

The mayor said the city has not ruled out a second, smaller plant somewhere else on the waterfront, adding the preferred location for the smaller plant seems to be in the eastern end of the Curling area.

No decisions will be made on the location until a full assessment of the drilling is done and the findings reported back to the city by CBCL Limited, the consultant hired by the city to look into building the plant.

In the meantime, Pender said the city will be sending a contingent to sewage treatment plant sites elsewhere in Atlantic Canada later this month to see how things are done at those locations.
