I am sorry that An Taisce is getting so much abuse. We need environmental watchdogs. I understand how there is great concern in country areas about objections to building and note that the reports on water quality by the Environmental Protection Agency have identified private water schemes as being polluted by e.coli which can only originate in either animal or human waste. All too frequently it is suggested that one-off housing is a problem. I questioned the relevant Minister, Deputy Ó Cuív, about the matter in the House and he insisted that sewerage systems were very well maintained. In many cases one-off septic tanks are not cleaned with the desired regularity. Rather than cursing An Taisce which is trying to raise standards in environmental issues such as the supply of clean water we should acknowledge that what it is objecting to is a very unfortunate source of pollution. I would be happier if it were insisted upon that one-off septic tanks were cleaned regularly.
