The Context

An economical solution, simple and quickly installed

Located in a residential area, the storm sewer system included the addition of a manhole and a catch basin interconnected by a 200 mm (8 in) pipe and a connection to an existing concrete culvert 600 mm (24 inches) in diameter. This underground system had to carry rainwater while meeting critical aspects, including lifespan, ease of installation and speed of discharge during strong rain events.

The Solution

A manhole with smooth exterior wall, 900 mm (36 in) in diameter and a corrugated catch basin 600 mm (24 in) diameter were installed, connected by a Solflo Max pipe 200 mm (8 in) in diameter placed in a trench 2 m (6.5 ft) wide by 1.6 m (5.2 ft) deep. A Solflo Max pipe 600 mm (24 in) in diameter and 6 m (19.6 ft) in length was used to connect the new system to a concrete culvert of the same diameter already in place.

Thanks to the bells with integrated gasket and clips (BIGC) installed on the pipes, installation was done very quickly. They are easy to cut, which allowed us to quickly adjust the length of the last section connected to the outlet of the already welded catch basin.

Philippe Losier, P. Eng. and Matthew Davis, sales rep, were excellent in solving our design problems. They came on site to better understand our expectations before the start of the project and visited the site at different times to ensure that everything was in order.
