A spokesperson commenting generally on the use of storm overflows said: "Storm overflows are sometimes used during heavy rainstorms to protect properties and roads from sewer flooding by releasing stormwater into watercourses.

“While it’s extremely rare for storm overflows to cause a sewage pollution incident, we’re committed to completely eliminating the discharge of any untreated sewage. Every month we’re investing £3million to reduce storm overflows, starting with those which discharge most frequently or which have any environmental impact.”
