Vancouver has a way of treating it's drinking water and that is in two stages. It is first treated at the source then given secondary treatment as it travels through different regions (Burnaby, Coquitlam etc.). This process of treatment ensures your water is safe and clean when it reaches your home or business, even miles way from the source.
As Hydro is responsible for electricity across the lower mainland, Water suppliers are responsible for delivering safe drinking water. This water must meet the requirements of the Drinking Water Protection Act and Drinking Water Protection Regulation. If there is a problem with the water the purveyors must notify the public!
Metro Vancouver has it's own way of filtering water. It has built a water filtration plant that treats most of Vancouver's water that is supplied throughout the region. The location of this plant is in the LOwer Seymour Conservation Reserve, very downstream of the Seymour Reservoir.
This filtration process includes the following steps:
With less chlorine required and fewer organics in the water, the level of disinfection by-products will also be reduced. For Vancouverites, the filtration process improves the taste, colour, and smell of the water.
Needless to say, we're very blessed to have such a high standard for tap water in the Vancouver region.
