Where and when does dirty water usually occur?

Residents living in areas furthest away from the nearest reservoir, or at the end of a street, may experience discolouration more frequently than others. This is because the water has further to travel and this allows heavier particles to settle out of the water and become visible. Weekenders or untenanted houses in any area may also experience discolouration when first turning on a tap after a period of time without using water at the home.


Discolouration can also be caused by old household connections as well as certain types of pipes. For example discolouration will occur more often in houses with galvanised water pipes. Galvanised pipes are no longer used in homes, with copper - or more recently polyethylene pipes have become the norm. Anyone who experiences regular water discolouration and has galvanised water pipes in their home may consider replacing them and should seek further advice and assistance from a local plumber.
