What Makes North Delta's Water Unique?
Local geology and source profile
The City of Delta Water Utility supplies North Delta, British Columbia, Canada, as part of the larger Metro Vancouver regional system. The vast majority of the water, around 97%, comes from three surface reservoirs: Capilano, Seymour, and Coquitlam. These sources are located in the Pacific Ranges of the Coast Mountains. A small amount of water is supplemented by groundwater. Treatment takes place at Metro Vancouver's facilities, specifically the Seymour-Capilano Filtration Plant and the Coquitlam Water Treatment Plant, before being distributed to over 100,000 residents in North Delta.
The water originates from the Capilano, Seymour, and Coquitlam watersheds. The underlying geology consists of granitic intrusions and metavolcanic rocks dating back to the Mesozoic era, with a covering of Quaternary glacial deposits. Crucially, there are no significant limestone or dolomite formations in the area. This type of resistant, acidic bedrock, combined with thin soils and extensive forest cover, means the water picks up very few minerals. Consequently, the water is characterized as being very soft with a low overall mineral content.
Because the water is very soft, residents typically won't experience scale buildup in their pipes, appliances, or fixtures. This means you're less likely to encounter issues with water heaters, dishwashers, or washing machines due to mineral deposits. You'll also find that soaps and detergents are highly effective, requiring less product to achieve a good lather. Installing a water softener isn't necessary and could even be detrimental, potentially increasing corrosion in the distribution system. Regular checks for general pipe wear are sufficient for maintenance. The City of Delta's drinking water is consistently reported to meet or exceed both provincial and federal quality standards.
