Water quality: taste and smell

The following is a brief guide to the most common water taste and smell problems.

Chlorine Taste

1. Why do we add Chlorine?
  Chlorine is added to the water to ensure the absence of harmful organisms.
2. Is the level of Chlorine we add to the water always safe?
  The level of chlorine in your water is well within the guidelines set by the World Health Organisation (WHO).
3. Are there variations in the levels of chlorine?
  Chlorine is added continuously at a constant rate and if we have to increase the level to maintain the standard of protection these changes are carried out very gradually. Usually customers only notice a difference when they move to an area with slightly higher chlorine residual.
4. Can I remove chlorine from my water?
  You can opt to use a jug filter or install a permanent carbon filter on cold water feed. Please remember that choosing this option will remove the protective chlorine and if this water is not used within 12 hours it can deteriorate.
5. I've noticed a sudden change in the taste.
 

The most common problem arises because of the contact of a small amount of chlorine in the water with domestic appliances or fittings that can cause a noticeable disinfectant taste.
We add chlorine continuously at a constant rate. If we ever have to increase the level of chlorine to maintain the standard of protection, these changes are carried out very gradually.
