A northwest Calgary community's sewage system will soon be able to handle more flushes, according to plans unveiled by the city Monday to build more waste pipes.

An open house was held Monday night at the Bowness Community Centre to give residents an idea of what to expect as Phase 1 begins this fall. Dozens turned out, hoping to find answers to concerns about what the construction will mean for them.

"Things like noise vibration, that would maybe do damage to our homes, because they're going to be tunnelling,” said Betty Jacobs, a Bowness resident whose home sits right beside a planned construction area.

“Also, would they cut off access to our homes? And they've assured us there's going to be minimal interruption that way."

Starting this fall city crews will install three kilometres of pipes using a microtunnel.

The goal is to help the area's strained sewage system keep up with the growing number of flushes.

Currently, the area is under a new building freeze to avoid overloading the system and causing backup into homes and businesses.

Ward 1 Coun. Ward Sutherland says crews are trying hard to make this easy on residents.

"They've taken great care and mitigation of putting a sound wall up, owning open area, trucking won't happen during the night time, only in the morning,” said Sutherland.

“They've taken every precaution to make sure that it's least intrusive."

Phase 1 is expected to be completed by 2016. Phase 2, however, won't begin until 2024.
