“We are very happy with the work completed, and relieved our community is better protected against future flood water. We were concerned given the environmental obstacles that were uncovered in the beginning of the process, but we are very happy with how these concerns were addressed. We appreciated the respect Walker showed for our community and surrounding environment.”

The Chippewas of Nawash First Nations undergoes community repair after flood damage with environmental sensitivity top of mind.
Cape Croker, Ontario
Bid to repair damaged culverts, water mains and roads leads way for culverts and long term surface water diversion infrastructure.
Chippewas of Nawash Unceded First Nation put out a request for tender to repair severe flood damage to their community. Flooding ravaged 90% of the roads and drainage infrastructure in October 2016, and in 2019 Walker (formerly Harold Sutherland Construction) secured the bid to repair damaged culverts, water mains and roads.
Operating in an environmentally sensitive area of the Bruce Peninsula, Walker carefully removed damaged and aging infrastructure and installed replacement water mains, realigned trenches and established new ditching. Two major components to the project included installing two new large concrete structural box culverts, and constructing surface water diversion infrastructure so that future flood waters were safely channeled to Georgian Bay to protect the community’s sensitive environment and existing drainage infrastructure.
Working with local suppliers, Walker installed new poly-laminated corrugated steel pipe (CSP); water mains, including hydrants, joints and valve boxes; and structural box culverts. Geotechnical engineers reviewed and tested the area and found that ground conditions consisting of marshy watercourses required additional support for the box culverts. This resulted in the installation of helical piles to provide stability to the concrete culverts.
Walker’s skilled construction team worked with multiple stakeholders to design and install a solution that met the required specifications of the project in a very unique and sensitive environment. Indigenous Services Canada, Associated Engineering and Walker applied their expertise to create a solution that would satisfy the Chippewas of Nawash Unceded First Nation community, the Band Council and Chief.
