Many issues will impact on the Dublin Bay South by-election. One that Brigid Purcell, the candidate for People Before Profit, has been campaigning on for some time and that we hope will feature relates to the commitment in the programme for Government to deal with the wastewater problems in Dublin Bay and the ongoing discharges of untreated sewage effluent, both from the water treatment plant at Ringsend, which is under capacity, and also from multiple locations around Dublin Bay, especially when it rains. There are many aspects to this but I want to ask about one which I did not know about. There is an ultraviolet treatment facility in Ringsend that reduces the microbiological effluent in the discharges into the bay, where one in five bathers are getting sick as a result of poor water quality.

I thank the Deputy.

It is only being switched on between June and September. Will the Tánaiste or the Minister ask Irish Water to switch on the ultraviolet treatment of discharges into Dublin Bay for the entire year?

I thank the Deputy. I was not aware of that. I will certainly check it out. There may be a good reason for that that the Deputy and I do not know but it sounds strange. I will make inquiries and get back to the Deputy when I have a reply.
