Drainage performance

Drainage performance

Quantities of gullies inspected and cleaned per year.

To minimise flooding across roads and provide an effective highways drainage system, we maintain approximately 116,000 gullies.  In order to maintain them, we carry out regular inspections to fix, clean and empty them. 

As we become more efficient with keeping our gullies maintained, the number of gullies that need to be emptied and fixed are reduced. 

The table below shows the number of gullies which have been emptied and attended by our gully crews over the last five years:

Year Emptied Number attended
2019 4261 5327
2020 47003 59903
2021 19237 34066
2022 17826 20590
