Storm drain emergency

A storm drain emergency is an urgent response to surface water drains overwhelmed by intense rainfall, blockage or system failure. Common causes include leaf and silt build-up at road gullies, blocked yard channels at lower entrance areas, and undersized rainwater systems failing during heavy rainfall. Across Greater London, storm drain emergencies peak during summer convective storms and autumn leaf-fall periods. Before the engineer arrives, occupants should clear surface debris from accessible gullies, divert water flow away from buildings using sandbags or boards, and document the event with photographs. The service includes blockage clearance by jetting, root removal, channel cleaning, and a written report. Why response time matters: storm flooding can damage building fabric, basements and electrical installations rapidly. Buildings insurance may cover storm drainage failures, depending on specific cover and policy excess.
