The pH and alkalinity of the Metro Vancouver drinking water
Effective June 7, 2021, to protect copper pipes and hot water tanks in buildings, Metro Vancouver increases the pH and alkalinity of the region’s drinking water through the use of natural minerals. This increase will:
- Reduce the release of copper from pipes in buildings caused by low pH in the region’s water;
- Reduce leaks in pipes caused by copper corrosion;
- Help preserve the lifespan of pipes and hot water tanks; and
- Reduce green stains on tubs, sinks, and grout.
Metro Vancouver currently delivers water with a pH of 7.7, which is compliant with Health Canada’s Guidelines for Canadian Drinking Water Quality, which range from 7 to 10.5. Adjusting the pH is an existing key component of Metro Vancouver’s water treatment process because our untreated source water is naturally slightly acidic.
Increasing the pH to a target range of 8.3 to 8.5 will make the water less corrosive. To help improve the stability of the target pH level in the water transmission and distribution pipes, the alkalinity will be doubled to about 20 mg/L (expressed as calcium carbonate) using natural minerals. Alkalinity is a measure of the buffering capacity of the water to neutralize acids and bases to help maintain a stable pH level. These changes might prompt some water users such as health care facilities and breweries to adjust and calibrate their operations to the change in pH and alkalinity.
Metro Vancouver will continue to deliver high-quality drinking water throughout the region that tastes and smells the same.

Managing Internal Water Systems
Water leaks are often the source of damage and insurance claims in multi-family buildings. This bulletin covers the life cycle management of water systems in multi-unit residential buildings, including strata housing, rental buildings, and co-operative housing.

Power Generator Safety at home
Using a Generator Safely at Home
Using a portable generator after a power outage is definitely handy, but generators can be dangerous if they’re used incorrectly. Be cautious and always follow all safety instructions provided by the manufacturer. The following are some safety tips and information about the dangers of home generators. You should consult a professional for assistance when installing a home generator and for advice with respect to your specific circumstances and generator type.
Setting up your generator
- Start by making sure the generator has all the necessary safety labels.
- Make sure the generator you purchase is rated for the power that you think you will need.
- Find a qualified electrician to install the generator in a safe location.
- Before using a generator make sure the unit is properly grounded and follow the instructions and electrical codes carefully.
- When in doubt always ask a professional.
Potential Hazards
The two main hazards to be aware of when using a generator are electrocution and carbon monoxide poisoning. Portable generators can also be fire hazards.Electrocution
- Losing power during a flood is not uncommon. However, never use a generator in a flooded basement. It’s important to keep the generator in a dry place.
- Make sure to protect the generator from rain and cover it with a canopy if necessary.
- Always operate the generator in a dry place and make sure your hands are dry.
Carbon Monoxide Poisoning
- Carbon monoxide poisoning happens when someone breaths in too much carbon monoxide, an odourless colourless gas that can be deadly.
- Be sure to keep the generator somewhere with proper ventilation.
- If the generator is outside, don’t place it close to any windows or vents because carbon monoxide can build up inside.
- Have working carbon monoxide detectors throughout your home and check the batteries frequently. If the detectors are wired to the house’s electricity supply, make sure they have battery-powered back-ups.
- The symptoms of carbon monoxide poisoning include dizziness, headaches, nausea and tiredness. If you experience any of these symptoms go outside for fresh air immediately.
Fire Hazard
- Generators become extremely hot during operation.
- Let the generator cool down and turn it off before refueling. Never refuel the generator while it’s still hot.
- Store your fuel outside in approved containers. Don’t store any fuel near a fuel-burning appliance or the generator itself.
