DRAGADOS - TOMLINSON JOINT VENTURE WINS IMPORTANT WATER INFRASTRUCTURE PROJECT
The Dragados - Tomlinson Joint Venture has begun construction on the Combined Sewage Storage Tunnel (CSST) to enhance the health of the Ottawa River by improving the storm water management system.
It will reduce the frequency of sewage over ows into the O awa River during major rainfalls and decrease the risk of basement  ooding for several low-lying lands in the core of the city. The City of O awa awarded the construc on project to Dragados-Tomlinson in July 2016 as part of its O awa River Ac on Plan.
“We all know that when we have extreme downpours or rapid mel ng, that water has to drain somewhere,” explained Paul McCarney, Vice President, Business Development, Tomlinson. “It goes into the sewer system and you get this mixing of stormwater with sanitary sewer  ow (human waste) that some mes discharges into the O awa River instead of the
treatment plant. When beaches are closed, it’s not about bird or animal droppings.”
Funded by the Government of Canada, the Government of Ontario as well as the City of O awa, total investment in the CSST project is approximately $230M over three years. Protec on of the O awa River has been a priority of the City, which is working to reduce the impact of both combined sewage over ows and storm water on the river.
Two tunnels, each about three metres in diameter, will stretch over six kilometres under the city core. One 2.2 kilometre tunnel will run north-south under Kent Street from Highway 417 to the Supreme Court on Wellington
