Mr. Se?n Laffey:

I would not say we are unique. Scotland has similar typography to us, as does Wales. A lot of the plants that were put in, from a technical point of view, will perform fine during the summer when the water is quite clear but during heavy rainfall events, a lot of organic matter is washed in and the plants are not technically capable of removing those organics. In Irish Water, we have the expertise to make sure the plants we invest in are capable of removing the organics and therefore the THMs.
