Drinking Water

About Public Drinking Water Supplies


Water that looks, smells, and tastes good, is safe to drink.


Some harmful contaminants can exist within a water supply that can only be detected by specialized testing. The only way to know for sure that your water is safe is to have it tested on a regular basis.

Access to clean drinking water is essential for good health. Our bodies need about two and a half litres of water a day. Water transports nutrients throughout the body, aids in the elimination of waste, and helps maintain the delicate electrolytic balance within cells. We must have clean water to drink.
