Mr. Seán Laffey:

Just so the Senator knows, if we are looking at Ringsend, where we spent €500 million adding additional capacity, that cost about €300 per PE, which is person equivalent. Some of the smaller treatment plants can cost up to €15,000 per PE, so anything we can do to build them off site to a standardised design and standardised output, do and the M and E in a nice, warm, dry factory, and then just go out to site and drop them, plug and play, should bring the cost down substantially, which means we can deliver more of them.
