A former Mayor of Narberth fears the area could soon be facing a stomach bug epidemic if action is not taken to combat raw sewage problems in the town. At a recent meeting of the town council, Clr. Henry Langen claimed heavy rainfall had caused foul water to run into the storm drain at Narberth Bridge and be discharged into the river. Clr. Langen explained that the river flowed from Narberth down to the water abstraction plant at Canaston Bridge. He feared that the area could soon be facing a similar situation to that in North Wales, where thousands of householders were told to boil their water after the cryptosporidium bug was detected in it. In the interests of safety, Clr. Langen asked if a letter could be sent to Dwr Cymru and to the Environment Agency. The town's county council representative, Clr. Wynne Evans, has also joined the campaign for action and has called for a site meeting with all interested parties. "I have received a positive response and I am optimistic," Clr. Evans told the Observer. "I feel a personal approach and a site meeting with all bodies, the Environment Agency, Dwr Cymru and Pembrokeshire County Council, will ensure this matter is resolved quickly." Said Environment Agency Wales spokesman, Martin Watkins: "The Combined Sewer Overflow (CSO) here is a consented discharge point in extreme weather conditions (eg. storm conditions). "The agency have been made aware of some evidence of discharges recently, and have arranged for a meeting between our environment officer who covers the area and local councillors. "This is due to take place on site at 2 pm on Wednesday. "The CSO is due for upgrading and is in Welsh Water's latest Asset Management Plan (AMP4) 2005-2010. The agency expect it to be in place by the end of 2009." Meanwhile, a statement from Dwr Cymru Welsh Water, said: "The combined sewer overflow at Narbeth Bridge is functioning as originally intended, discharging storm water discharges during times of heavy rainfall to prevent the flooding of properties in the locality with waste water. "As part of Dwr Cymru Welsh Water's investment programme for 2005-2010, the combined sewer overflow is scheduled to be upgraded to deliver further environmental improvements to the area. Work such as this is planned on a priority basis which is why the £500,000 upgrade is planned to take place during 2009." The spokesman also confirmed they had been informed of the meeting next week.
