A wet weather overflow is a spillage of untreated sewage and stormwater from sewer pipes that occurs in wet weather when the hydraulic capacity of the sewer is exceeded. During heavy rain, stormwater enters the sewerage system through cracks and faults in the pipes and via illegal plumbing connections, gully pots and openings in manhole covers.
