Frequently Asked Questions
What is the Hanlan Water Project?
The Hanlan Water Project is the construction of two watermains:
- The Hanlan Feedermain is 2,400-mm (8 feet) in diameter and will carry water from Lakeview Water Treatment Plant on the shores of Lake Ontario to the Hanlan Reservoir and Pumping Station on Tomken Road and Britannia Road.
- The Mississauga City Centre Subtransmission Watermain is 1,500-mm (5 feet) in diameter, and will carry water from Hanlan Reservoir and Pumping Station to the Mississauga city centre core area.
Why do we need the Hanlan Water Project?
The Hanlan Water Project is needed to meet the water demands of future planned and approved Regional growth, including in the Mississauga city centre core.
The new feedermain will provide backup and flexibility if the existing Hanlan Feedermain needs to be temporarily shut off for inspection or repair.
It will also help to fulfill the Region's obligations to York Region, made under the York-Peel Water Supply Agreement in February 2002.
Why is this project important to me, my family and my neighbours?
As the Region of Peel grows and as our existing water network ages, we must produce a larger amount of drinking water and deliver it reliably to homes, businesses and institutions throughout Mississauga, Brampton and parts of Caledon
The Hanlan Water Project is part of Peel's commitment to provide you with a dependable supply of clean, safe drinking water.
What is a feedermain?
A feedermain is a large diameter watermain that services a sizeable population, carrying water from one reservoir or pumping station to another.
What is a subtransmission main?
A subtransmission main carries water from a pumping station to smaller, local distribution watermains. Distribution watermains are the same as those that feed your house or business.
When will construction begin and end?
Construction began in late 2011 and should be completed by mid-2016.
Construction started along Lakefront Promenade, and will be completed in sections.
How will the Hanlan Water Project be built?
Part of the work will be done by tunnelling, and part will be done by open-cut construction.
What is open cutting?
Open cutting involves digging a trench to install new water infrastructure or to upgrade existing water infrastructure. Because it is surface work and typically extends over long stretches of land, it can cause some traffic disruption along the construction route.
What is tunnelling?
Tunnelling is completed by digging two shafts and using special equipment to tunnel beneath the surface of the road between the shafts. As the work takes place mostly underground, it can be less intrusive than open cutting. Tunnelling limits disruptions to shaft-site locations, where construction activities are concentrated.
Why can't you tunnel the whole route?
Tunnelling can be very expensive, and it would not be cost effective to tunnel the whole route. However, in areas where greater disruption would be caused by open cutting, such as major intersections or where there are complex utility networks in place, it can be more economical and advantageous to tunnel.
We will also tunnel environmentally sensitive areas such as the Etobicoke Creek.
How will traffic be affected and how will traffic flow be maintained during construction?
Lanes will be closed while we are working in an area. We will do everything we can to make sure disruptions are kept to a minimum.
We'll keep you informed of impacts to traffic through our website, Twitter, local media and electronic roadside signs, or you can call our Drivers' Hotline at 1-855-hanlan 1 (1-855-426-5261).
