What Makes Port Moody's Water Unique?

Local geology and source profile

Source: ReservoirTDS: 220.8 mg/LpH: 7.6

The City of Port Moody receives its water supply from Metro Vancouver (GVWD). The primary source is the Coquitlam Lake reservoir, located within the Coquitlam watershed. This reservoir collects water flowing from the surrounding mountains. The raw water then travels through a distribution system to reach homes and businesses within the Tri-Cities area, including Port Moody residents. The water undergoes treatment processes before being delivered for consumption.

Water flowing from the Coquitlam Lake reservoir originates in the lower Coast Mountains. The geology of this region, characterized by igneous and metamorphic rock formations within the Coquitlam watershed, contributes to the water's mineral content. These natural geological processes result in water that is classified as moderately hard, with a typical measurement of 5.3 grains per gallon (gpg).

This moderately hard water can lead to the buildup of scale in household appliances and plumbing over time. You might notice it affecting the efficiency of your water heater or causing spots on glassware after washing. To combat scale, regular descaling of appliances is recommended. While a water softener isn't strictly necessary, it can improve the performance of soaps and detergents and extend the life of your fixtures. The taste is generally considered good, with no specific mineral aftertaste reported.
