The Hanlan Water Project includes the installation of a 2400-mm (2.4 metres or 8 foot) diameter Hanlan Feedermain and a 1500-mm (1.5 metres or 5 foot) Mississauga City Centre Subtransmission Watermain.
The feedermain will run approximately 14.5 kilometres from the Lakeview Water Treatment Plant on Lake Ontario to the Hanlan Reservoir and Pumping Station at Tomken Road and Britannia Road East.
The subtransmission main will run approximately six kilometres from the Hanlan Reservoir and Pumping Station to the intersection of Cawthra Road and Burnhamthorpe Road.
Work also includes local distribution works, road improvements and wastewater collection improvements along the route.
Construction began in 2011 and is scheduled to be completed by early 2017. Construction will be done in two ways:
- Open cut – Digging a trench and laying the water pipe in the trench
- Tunnelling – Digging two shafts and using specialized equipment to excavate beneath the surface of the road to install the pipe
