Highway drainage helps prevent flooding, severe ponding and keeps the carriageway free of standing water


Highway drainage systems are installed to capture surface water, this helps:

  • Alleviate flooding
  • Protect the integrity and fabric of the road
  • Assist with the safety of road users

It is our responsibility to oversee all matters relating to highway drainage within the Vale and to provide information and advice to you and other members of the public.


Please note: All drainage systems have a maximum core capacity for the transportation of rainwater. No system can give absolute protection from flooding events.
