Floodex | National Drainage Show | Waterways Management Show 2026

Floodex, the National Drainage Show and the Waterways Management Show are three co-located exhibitions at ExCeL London for professionals who manage flooding, drainage and waterways. Launched in 2016, Floodex takes a holistic view of flooding: the National Drainage Show focuses on surface water runoff, which the organisers say causes 70% of flood incidents, while the Waterways Management Show looks at catchments and the health of rivers and canals. The shows run alongside the National Civils Show, with no walls between the events.
