“
A bellmouth gully inlet is a type of drainage or stormwater inlet commonly used in civil engineering and urban infrastructure to collect and manage surface water runoff. It is designed to capture rainwater and direct it into the underground drainage system, preventing flooding and waterlogging in urban areas.
The term “”bellmouth”” refers to the shape of the inlet, which resembles an inverted bell or funnel. The bellmouth structure has a wide, flared opening at the top, gradually narrowing down to a smaller pipe or drain at the bottom. This design allows for efficient capture of water, especially during heavy rainfall or high-flow conditions.
Bellmouth gully inlets are typically made of concrete or other durable materials and are installed at strategic locations along roads, sidewalks, parking lots, and other paved surfaces to collect and convey rainwater to stormwater drains or underground pipes. These inlets are often fitted with grates or screens to prevent debris and large objects from entering the drainage system, which could potentially cause blockages and further exacerbate flooding issues.
Overall, bellmouth gully inlets are an essential component of urban drainage systems, helping to manage stormwater runoff and protect communities from the adverse effects of excessive water accumulation during rain events.”
