150mm Gravity Storm

Antigonish, NS

A local customer approached us with a challenging project - Reroute the water in the ditch in front of their home to the back of the property to prevent water from backing up into the basement. A few challenges stood in the way of traditional open cut methods. Firstly, the property elevation sloped hill up over 2m from the front to the back and secondly, the county sanitary sewer main runs through the property with invert at nearly 2.7m.

We planned a drilling profile that would cross under the sanitary main and exit out the back of the property, allowing the new 90m 150mm pipeline to run on a negative grade, eliminating any need for mass excavation, saving the landscape and improving installation speed and safety.
