Non-Potable Water (Whitewater)

Where possible UCD uses non-potable water such as rainwater and well-water for a variety of uses.
Well-water or white-water as it is also known, is an important sustainable source for UCD. This water which is drawn from the ground from on-site wells is primarily used for pitch irrigation, cleaning and plant watering. Water not taken up by the plants or grass is therefore returned to the water cycle and is much more sustainable than using potable treated water.


There are many advantages to a non-potable water system

  • Makes use of a natural resource, reducing the use of potable water
  • Reduces the demand on Irish Water Network
  • Excellent source of water for landscape irrigation
  • Promotes water conservation
