The City of Toronto has identified major watermains between Spadina Avenue and River Street that need to be replaced to increase capacity and maintain the safety 
and reliability of the
water supply. This project is part of the Toronto Water cast iron watermain replacement program. A Municipal Class Environmental Assessment (Schedule A) study was completed in January 2008 to determine a preferred route for the replacement of the watermain. Construction of the very large pipe will be done by tunnelling underground, which minimizes traffic delays and community disturbances.

Construction Details
The main watermain route goes from Spadina Ave., along D’arcy St. to McCaul St., continuing north on McCaul St., east on Elm St., north on Elizabeth St., east along Gerrard St., turning south on River St., and ending at Mark St. A secondary segment will also include Beverley St. from D’Arcy St. to College St. Construction will be done at various locations going in different directions.
Construction will be done by tunnelling the watermain underground, which minimizes traffic delays and community disturbances.
The tunnelling process will require the construction of seven large tunnel shaft sites along the route. Tunnel shaft sites provide an area to launch and operate the tunnelling machine and allow for the removal of soil and other material.
Construction will take about 12-21 months at each shaft site, with the exception of Allen Gardens south east corner, which will contain a construction site for the full three and half years.
Construction work will also be required for smaller valve chambers and connection sites along the route. Work at each smaller site will vary from one to eight months.
Construction Sites Schedule
(The preliminary schedule for all construction sites will be published soon. Updates and further details to be provided as work progresses).

Work will typically take place from 7 a.m. to 7 p.m. from Monday to Friday, with work after hours and on weekends as required.
Disruptions
During construction there will be restrictions to turning, parking and driving lanes in and around each shaft work area. Advisory signs will be put in place. Access to all businesses and residences will be maintained on both sides of all roads at all times during construction.
From time to time residents may experience vibrations, dust and noise from the excavation and tunnelling equipment, including back up beepers from trucks.
The water supply to local properties should not be affected by this construction project.
Notice will be given to surrounding properties prior to construction at each site, including an updated schedule. Every effort will be made to reduce inconveniences. The City appreciates your understanding and co-operation.
