Every day, residents, businesses and industries in Metro Vancouver produce about 1 billion litres of wastewater. Most water becomes wastewater by being “used” in some way. About 80% of the region’s wastewater comes from our homes, when we use toilets, sinks, showers, washing machines and anything else that sends water into a drain or pipe. Wastewater also includes stormwater, which is created when rainfall and snowmelt collects pollutants as it runs off streets, parking lots and other hard surfaces.
Our everyday activities add pollutants to water that need to be removed through a treatment process
. Wastewater will eventually end up back in local rivers and oceans, so how we manage it affects our environment and the livability of our region.
