Has anybody here ever bought a plastic bottle with a litre of water or drink in it? There is a thing called displacement. One can place a full litre bottle of water or stones in a cistern so that less water is needed to fill it but the toilet can still flush. People can do practical things like that to conserve water. In Ireland each person uses the equivalent of two full baths of water every day. To conserve water one can choose to take a shower instead of a bath. One can also buy a rainwater butt for €40 which will lead to significant savings in terms of water conservation. It is not rocket science and people can take simple steps to reduce their water usage.

Senator Ó Clocharthaigh is right that people can consult websites such as Dublin City Council's section called Tips for Taps. There is a lot of proactive information available and much of it is simple and common sense. It is not rocket science.
