Hanlan Water Project grows

A contractor outreach meeting/prequalification process planned for early 2012 has been delayed slightly on the Hanlan Water Project, in the Region of Peel, Ontario, due to the consideration for more tunneling.

The proposed Hanlan Feedermain is a 2.4m (7.8ft) i.d. pipeline running from the Lakeview Water Treatment Plant on the shoreline of Lake Ontario in Mississauga, Ontario, approximately 14km (8.7-miles) northward to the Hanlan Reservoir and Pumping Station.

The project is part of the Region of Peel’s 2007 Water and Wastewater Master Plan. Once constructed it will enhance the regional water supply, service commitments to growth and provide redundancy for the Region’s system.

The major tunnel component is a 6km (3.7-mile) long, 3.6m (11.8ft) diameter, TBM driven tunnel in shale under major highways and rail bridges. The Region is now considering extending this component from 6km (3.7-miles) to 9km (5.6-miles). In addition to the major tunnel component several additional tunnels of 2.4m (7.8ft) and 3.6m (11.8ft) diameter are required for lengths up to 1.4km (4,600ft). The Region is also now considering knitting together some of these shorter tunnels into longer tunnel segments. The 9km tunnel segment may be a separate contract or combined with the short tunneled segments.

The project is in the early stage of design by MMM Group and CH2M HILL and will be tendered to short-listed contractors in mid-2012. Further details on the prequalification process will be released in the coming weeks.
