With regard to the River Liffey, a very sensitive and important national resource, there is a view among the technical staff of local authorities that it is a source of water and a place to dispose of waste. It is not sustainable to keep taking more and more water out of Ballymore Eustace in order that it can be wasted in Dublin where, if there is a cold night, people leave taps on and let the water run without being penalised. Someone somewhere pays. Those responsible for wasting water should have to pay. Perhaps that is a matter for wider debate for another day.
