Mr. Seán Laffey:

We prioritise. If we are going to rehabilitate a water main, we look at the numbers affected, and we look at the loss of service to our customers. We can also replace a water main on the basis of quality. Some of the water mains are quite old, especially when they are cast iron. We cannot keep a chlorine residual in them so we cannot guarantee the water. We replace roughly 150 km of water main a year. That costs approximately €1 million a kilometre. A substantial amount of that €1 million a kilometre is resurfacing the road after we are finished. As I said, we have 65,000 km of water main. It is not a large investment in the grand scheme of things but €150 million a year is a lot of money to be putting into the water main side of it.

We invest in water treatment plants for extra capacity if required. We also invest in them to make sure they are producing compliant water. On the wastewater side, we invest in terms of environmental impact and improving-----
