Woolwich will spend $1.6 million to remedy some deficiencies in the water system supplying parts of Maryhill, tackling some drainage and groundwater issues while crews are at it.

A 900-metre section of watermain will be removed in the Maryhill Isley water distribution system, the ductile iron material replaced. Parts of the system used with that material, a compound using other materials such as carbon and silicone, have deteriorated since being installed in 1972. Other parts of the system using cast iron, installed in 1968, are fine and won’t be replaced until down the road.

Meeting this week, Woolwich councillors awarded a $1.36-million contract to Regional Sewer & Watermain Ltd. to undertake the project. Engineering contracts, additional work and contingencies bump the total cost to $1.6 million.

The work being done this year is needed due to water quality issues associated with ductile iron. The township has been unable at times to maintain adequate levels of chlorine residuals in the system, requiring more maintenance and higher costs, reported project supervisor Jarred Puppe.

Drainage issues identified in preparing for the project will see crews restore roadside ditches on Notre Dame Avenue that have been filled in. Deficiencies in the storm sewer on St. Charles Street East will be addressed.

As well, a 114,000-litre fire reservoir will be installed near the entrance of the community centre, at a cost of $73,000, to serve as a backup should it be needed while the watermain is being replaced.

Work is scheduled to get underway May 6, and be completed by September 27. It will be done in two stages: Notre Dame Avenue and Isley Drive, followed by St. Charles Street East.

Regional Sewer & Watermain Ltd. was the lowest bidder. Fifteen tender packages were picked up, with eight firms bidding on the work, indicating contractors are looking for work, said director of finance Richard Petherick.

“They’re hungry out there.”
