Brampton’s stormwater management system collects, moves and manages runoff from melting rain or snow. Unlike wastewater, which receives treatment before release, stormwater flows directly into local rivers, creeks and stormwater ponds before reaching Lake Ontario. Lake Ontario provides drinking water for over nine million people, including Brampton residents. Everyday activities such as washing cars in driveways or using excess road salt during winter can pollute stormwater and harm the local waterways.
