White water

Is the water coming out of your taps cloudy or milky?

Drinking water can sometimes appear ‘milky’ or ‘cloudy’ when first drawn from the tap. This is usually caused by air and generally disappears after a short time.

If your water is white, milky or cloudy, fill a glass with water and leave it to stand for a few minutes. If the cloudiness clears from the bottom of the glass upwards, this shows the cloudy appearance has been caused by air. The tiny air bubbles will rise to the surface and the cloudy appearance will disappear. You can see the effect in the photograph below.

Rest assured, cloudy water caused by tiny air bubbles in the water is not harmful to health. If, however, the water does not clear in this way, please Contact us.
