One of the most effective ways of doing this is to add carefully controlled doses of chlorine to the water. The results of all our tests are collected and kept at local offices. If you would like to see the water quality results for your area in more detail, you can inspect them there. We must make sure that the water we provide to you is safe to drink. Water contains many natural minerals that are picked up from the rocks and soil that the water passes through.
Bacteria also occur naturally in water.
They are picked up as rainwater makes its way through the soil and as it flows in streams and rivers. Most bacteria are harmless but some are not. If water carries disease causing organisms it can seriously damage our health. So we treat water in treatment plants to remove harmful bacteria from drinking water. One of the most effective ways of making drinking water safe is to add carefully controlled levels of chlorine.
