Project Highlights

The Pressure District (PD) 7 Elgin Mills Road Watermain Project consists of approximately 2.0 km of 600mm diameter CPP watermain along Elgin Mills Road in order to transmit water from the Richmond Hill Pumping Station to the PD7 area. The watermain connects at the west end to an existing 600mm diameter watermain at Enford Road and at the east end to an existing Regional 750mm diameter watermain located at Bayview Avenue. 

Cole Engineering provided Detailed Design and Construction Services for the proposed watermain and appurtenances along Elgin Mills Road from  Enford Drive to Bayview Avenue. The project involved crossing of three TRCA regulated tributaries, CNR crossing by MTBM, two jack and bore installations and 720m installed by Earth Pressure Balance Microtunnel MTBM method. Challenging ground conditions included artesian and perched water in variable soil types. The project also involved Permit to Take Water PTTW; groundwater control and disposal; connections to existing tapping and valves; vehicular and pedestrian management; and planning and control.
