Ms Mindy O'Brien:

Perhaps grants could be made available for the installation of facilities for the harvesting of rainwater, along the lines of the Sustainable Energy Authority of Ireland's low-energy grants. The use of low-flush toilets, low-flow shower heads and other low-water use appliances could be similarly incentivised. I suggest that grants or tax incentives should be introduced to discourage the use of large quantities of water within the house.
