Highway Drainage Lesson Learnt
- Targeted investigation from inventory data allows funding
to be prioritised and drives the correct maintenance
- treatment. More frequent gully cleansing is rarely the
most appropriate solution.
- Adjacent landowners and the water authorities have key
roles to play in ensuring the highway drainage system is not overloaded and operates effectively.
- Inventory condition data allows us to plan ahead for the
network maintenance needs.
