These trunk sewers are located at depths ranging from 16 - 30 metres below ground and the sewer pipes range from 2.3 metres to 3.5 metres high. There are 4 major components to the project:
- Tunnel excavation
- Installation of new pipes and shafts
- Connections to existing sewer pipes
- Conversion of existing double barrel pipe into full sanitary pipe
Construction crews make every effort to complete this necessary work with as little disruption to traffic flow as possible.
The project is scheduled for completion in August of 2017.
