CONCRETE PIPE Case Study Stormceptor Shines in Severe Storm Peterborough, Ontario: On July 15, 2004, Peterborough’s streets turned into rivers and cars became rafts as a record-breaking storm dumped 14 billion litres of water on the region in under five hours—the equivalent of water flowing over Niagara Falls for 40 minutes. In what Environment Canada estimated to be a 200-year event, thousands of homes and businesses filled with over two meters of water, forcing residents to evacuate and the city to declare a State of Emergency. At the height of the storm, storm sewer flow rates were five times higher than average, surging with stormwater filled with harmful pollutants. Emergency crews worked frantically to minimize the damage that was initially estimated at over $88 million. In fact, the cost to the city could have been much greater, both economically and environmentally, had it not been for the city’s 46 Stormceptor systems that effectively prevented pollutants from entering nearby lakes and streams. Peterborough’s Ounce of Prevention In 2001, Peterborough chose the Stormceptor oil and sediment separator because it removes more pollutants from stormwater than any other separator, treating the broadest range of particle sizes, as well as harmful hydrocarbons and heavy metals that attach to fine sediment. To ensure optimum performance, a maintenance and inspection plan for the Stormceptor units followed installation. Each of the region’s 46 Stormceptors was inspected by Minotaur Guardian Services shortly before the storm. Sources Report to the Standing Committee on Justice Policy (Peterborough Flood report).
