The Chief Executive of Water Service (Mrs. Katharine Bryan) has been asked to write to the hon. Lady in response to this question.
Letter from Mrs. Katharine Bryan to Mrs. Iris Robinson, dated
You recently asked the Secretary of State for Northern Ireland a Parliamentary Question as to whether recent sewerage spillages occurring at Whiterock Bay have been found to be directly attributable to the unscreened storm overflow located there. (217469). I have been asked to reply as the issue falls within my responsibility as Chief Executive of Water Service.
The unscreened combined sewer overflow to which you refer is situated on the main sewer in Whiterock to the northwest of the boat park. Its purpose is to prevent out of sewer flooding during periods of heavy rain, when the flow in the main sewer can exceed its capacity, by discharging the excess flow into Whiterock Bay. Combined sewer overflows are a common feature on many sewerage systems in the UK.
Water Service has no record of complaints about this particular combined sewer overflow or about sewage spillages in the Bay. However, if you can provide me with specific details of sewage spillages, I will have the matter investigated as a matter or urgency.
