Why can I taste or smell chlorine in my water?
Many people are able to taste or smell extremely low concentrations of chlorine in water and may be able to detect it in our water system. We have to maintain an adequate chlorine level at every customer tap to ensure the safety of the water and to meet regulations. If you live close to one of the places where we add chlorine, you will have more chlorine in your water than someone farther away.
How do I get rid of the chlorine taste and smell in my water?
An easy way to get rid of the taste and smell of chlorine is to fill a container of water and keep it in the fridge for drinking. Much of the chlorine will leave the water overnight. Cold water also tastes and smells better than water at room temperature. You will also save water since you don't have to run the tap until the water feels cold every time you want a drink.
Why does my water sometimes look dirty?
Dirty water problems can be caused by a wide variety of factors, including:
- old galvanized piping in buildings
- plugged water softeners
- hydrant use by the Winnipeg Fire Paramedic Service
- a change in the direction or in the rate of flow of water in the pipes (e.g., due to a water main break or leak), which stirs up sediment at the bottom of the pipes and/or rust from cast iron water mains
- operation of control valves to isolate a section of water main (e.g., water main cleaning program), which can disturb rust that has built up on cast iron valve components
While dirty water may not be pleasant to look at, nothing new has been introduced to the water distribution system. Wait until the water is clear before you drink it, do the laundry or use the dishwasher. Dirty water conditions usually go away quickly when left alone.
Why is my water cloudy once in a while?
Water is cloudy when air gets in it and makes tiny bubbles. The bubbles are harmless and will disappear if you let the water sit in a glass for a few minutes. Cloudiness appears more often in the winter when the water is cold.
Do you add fluoride to the water to help prevent tooth decay?
Yes. We add fluoride according to the Provincial Fluoridation Program guidelines at a level that helps prevent tooth decay and won't harm health. Many health-related organizations, such as the Canadian Dental Association, the Canadian Medical Association and the World Health Organization, recommend adding fluoride to drinking water.
Should I drink tap water if I have a special health concern?
You should ask your doctor this question if you have an extremely weak immune system. The following people may have an extremely weak immune system:
- people with HIV/AIDS
- people with cancer
- people with genetically weakened immune systems
- transplant and other patients taking immunosuppressive drugs
Should I use hot tap water for drinking and preparing foods?
We recommend that you use only cold water for drinking and preparing foods. Hot tap water can contain higher levels of metals, such as copper, because metals in water pipes and plumbing fixtures dissolve more easily in hot water. If you need hot water for cooking and drinking, draw water from the cold tap and heat it.
Where can I get information on bottled water?
Bottled water is regulated differently from municipal drinking water. It is regulated as a food by the Canadian Food Inspection Agency. If you have any questions about a specific bottled water product, call them at 
.
A four-litre jug of tap water costs less than a penny.
Where can I get information on water filters?
For information on water filters and other home water treatment devices, you can call the NSF International free hotline at 1-877-867-3435 or visit:
If you want to buy a water treatment device, Health Canada strongly recommends that you buy one certified by ANSI/NSF. Many of the water treatment devices that are on the market can help improve the taste, odour and appearance of the water. Some products will reduce or remove things like Cryptosporidium and trihalomethanes. All certified treatment devices have the ANSI/NSF marking on the product stating which standard it meets.
Follow the manufacturer's instructions for taking care of your water treatment device. Replace filters when recommended. A filter that is not working properly could produce unsafe water.
Where can I get more detailed information on water quality?
Visit Health Canada.
Where can I get more information on Winnipeg's drinking water quality?
Contact us or review our water supply system annual report or our drinking water quality report archives.
We will inform Winnipeg residents immediately if there is ever a water quality problem that could affect public health.
