City of Saint John Wastewater Flood Protection Project

pre-construction

The City of Saint John has some of the highest tides in the world and is at increasing risk of flooding from extreme weather, which is magnified by climate change. Two significant riverine flooding events have occurred on the St. John River in the past decade with the highest water levels on record, causing significant damage to infrastructure. The project will upgrade and rehabilitate 3 wastewater systems, mitigating the flooding risk and ensuring the provision of wastewater services to an estimated 32,600 people. The project will reduce or eliminate untreated wastewater discharge caused by flood damage and protect existing infrastructure from damage, as well as reduce expected sewer backup.
