Operating since 1917, the Ashbridges Bay Wasterwater Treatment Plant is one of Canada’s largest and oldest wastewater treatment plants. Oliver Ng Ashbridge's Bay is a bay and park in Toronto, Ontario, Canada.It is located along Lake Shore Boulevard next to Woodbine Beach in the Beaches.The Martin Goodman Trail and boardwalk run through the park along the bay. The risers are vertical stainless-steel pipes along the last kilometre of the tunnel which will diffuse the treated effluent in a wide direction.In describing the complexities of this phase of the project, Quarisa points out that once drilling through lakebed and rock is complete, the riser pipes are lowered and grouted in place.As the tunnelling work advances, the tunnel-riser connection work will be performed from the tunnel.

Surat and Bowen Basin, Australia The outfall tunnel at the ABTP conveys and disperses treated effluent from the Ashbridges Bay Treatment Plant into Lake Ontario. Hebei Province, Shangdong Province, and Shaanxi Province, China Scheduled to commence this fall, the tunnel boring of a seven-metre-diameter, 3.5-kilometre-long outfall underneath Lake Ontario from the Ashbridges Bay Treatment Plant in east-end Toronto may or may not be largest or longest of its kind in Canada.“But it will certainly be a major undertaking,” says Frank Quarisa, director of wastewater treatment with Toronto Water.Excavation will begin once a shielded rock tunnel boring machine, currently being manufactured in Mexico, arrives on site and it won’t be until 2024 that construction is completed.It is being built to improve capacity and better convey the effluent from the plant and will replace the existing at-capacity outfall which has been in service since 1947, he says.The tunnelling contractor is Southland Mole of Canada/Astaldi Canada Joint Venture and the consulting engineering team is comprised of lead consultant Hatch and Jacobs (formerly CH2M) and Baird.“All firms have a strong local presence and have thorough knowledge of the city’s wastewater infrastructure.”Capable of installing and grouting a precast concrete segmental tunnel lining system, the TBM will be operated in two shifts (up to 10 hours each), although the work could be extended to 24-hours-a-day if situations warrant it, says Quarisa.Some of the challenges which will be encountered along the route will include poor rock conditions such as weathered/cracked shale, hard rock layers and high-water infiltration, or gas pockets.Although mammoth in scale, the tunnelling is only one component of the overall project which is comprised of a significant amount of both onshore and offshore work. ROANOKE, Texas – Southland Holdings, LLC announced that their Southland Mole of Canada Division was awarded the Ashbridges Bay Treatment Plant Outfall (ABTP) contract by the City of Toronto earlier this month.
