Water Treatment Plants Turn to UV for Cryptosporidium Control

There is no doubt about it but Cryptosporidium remains a major threat to water supplies throughout Europe. Following an outbreak in 2005 Dwr Cymru (Welsh Water) has upgraded the Cwellyn Water Treatment Works which serves 76,000 consumers in North Wales, including Bangor and south Anglesey, at a cost of €15 million. The upgrade, carried out by Black & Veatch and supported by Mulcair, includes the installation of ultra violet treatment as well as several new treatment stages. The upgrade is part of a wider £200 million investment throughout Wales to improve the security of water quality in our supply area.
