You may not notice, but every water supply has its own distinct taste due to its composition. This is why you may notice a difference when you travel to a different part of the country.

Taste differences in water come from salts and the minute presence of specific metals such as iron, copper, manganese and zinc in the water. Some people are more sensitive to tastes and odours than others.

There can be a variety of reasons for people to notice a slight change in the odour or taste of their water. This could include:

Some customers describe this as smelling stale or pond like. It can have several sources:

  • By-products of algae or harmless micro-organisms in the raw water sources. In areas where we know this is a problem, we treat the water with activated carbon or ozone.
  • Long lengths of pipework within large buildings.
