There are more than 18,000 fire hydrants across the county. Each one can be located by a nearby yellow plate with a black 'H' on it.
All hydrants are underground beneath covers in the public footpath, roadside verges and roads. We use them to extract the water needed for putting out a fire.
We inspect more than 6,000 hydrants a year and carry out minor repairs and maintenance. Every hydrant is checked at least once every four years.
If you see a problem with a fire hydrant, such as leakage, damage to a cover and frame or “H” marker plate, you can report it.
It is illegal to use a fire hydrant for purposes other than firefighting, unless authorised by Anglian Water.
