Due to the City of Toronto’s aging sanitary infrastructure, sewer failures can often occur. During such a failure of a sanitary sewer in a river valley, Cooper worked with the emergency repair contractor to design a pump system to operate for the duration of the repairs. As there was no information on the flow rates in the system available, Cooper reviewed the site conditions and determined what would be required and provided a 100% redundant bypass system. Cooper was able to support this contractor with not only a pumping system but with general equipment rentals and Trench Safety equipment.
