Road Gullies and Road Drainage Systems: How Surface Water Is Managed Safely
Understanding Road Gullies in Modern Drainage Systems Road gullies are a fundamental part of surface water management across highways, car parks, footpaths, and public access routes. They are designed to collect rainwater from the road surface and channel it into an underground drainage network. By doing so, they help prevent standing water, reduce spray from vehicles, and limit the risk of flooding during periods of heavy rainfall. For anyone responsible for road design, maintenance, or asset management, understanding how road gullies function helps inform better drainage planning. Their placement, construction, and ongoing maintenance all influence how effectively surface water is removed from busy transport routes and shared public areas. What Are Road Gullies Used For? The primary purpose of road gullies is to intercept rainwater that runs off impermeable surfaces. Roads, pavements, and cycle paths do not absorb water, so rainfall must be directed elsewhere. Gullies provide a clea...
