Enwave - Deep Lake Water Cooling Expansion - Grouting Phase
Grout fill was installed in the 564m long anulus between a new 1600mm outer-diameter HDPE intake line and an existing, abandoned 1797mm inner-diameter steel intake line. Filling the space between the two pipes prevents the HDPE from possible collapse during under-pressure conditions. A custom, high-flow grout mix was developed for this purpose.
Enwave - Deep Lake Water Cooling Expansion - Slip Lining Phase
The slip-lining phase of the Enwave project facilitated the reuse of abandoned infrastructure and eliminated the need to excavate a 600m long trench (through marine habitat) from the beach at Centre Island into Lake Ontario.
Enwave - Deep Lake Water Cooling Expansion - Test Pigging Phase
The test pigging phase of the Enwave project was performed to ensure that the planned slip-lining operation was feasible.
