What is a fire hydrant?
As you go about your daily life you probably pass at least one fire hydrant as there are over 22,000 in Norfolk alone.
Contrary to popular belief they are not the above ground pillar type hydrants as seen in American films, but are underground. You may be familiar with above ground yellow marker posts, used to identify the location and size of the water main, however the hydrant is a tap under the road that requires a standpipe to access the water supply. It is marked with the letters F.H.
Take care not to park your car above or too close to a fire hydrant as it could be needed in an emergency at any time. They are used to either supplement the water supply for fire fighting or to supply/refill the tank in a fire appliance
Norfolk Fire and Rescue Service has a statutory duty to take all reasonable measures to ensure there is an adequate supply of water and it is available for use in case of a fire. Maintaining fire hydrants in good working order is very important to our operational response to allow effective fire fighting activities.
Where dry riser facilities are provided within buildings, for this purpose, we are able to offer our specialist inspection, testing and maintenance expertise to help building owners ensure that the equipment is available for emergency use if it is ever needed.
Dry rising fire mains should be checked every six months to ensure that all valves are fully serviceable and a wet pressure test should be carried out annually to ensure that there is no leakage in line with the procedure laid down in British Standard 9990:2015.
For details of our charges for this service please contact the Water Officer by email water.officer@fire.norfok.gov.uk or call 0300 1231165
Six-monthly inspections
This is a dry visual inspection of the inlet and each outlet. All inlets, outlets, landing wheel valves, and washers are checked to ensure they are in a satisfactory working condition. Where necessary washers, blanking caps and straps etc will be supplied and fitted at the time of the test (at an additional charge) to comply with British Standard.’
Annual wet pressure test
This test ensures that water can be passed through the system under pressure, with no leaks, and a static pressure reading is recorded. In order to comply with the relevant British Standard the test includes the riser being charged with water at 12 bar pressure and held for 15 minutes without leakage.
Inability to sustain effective fire-fighting jets from the top or furthest outlets, or any undue pressure loss in the rising main (after allowing for any height involved) is highlighted for investigation.
All inlets, outlets, landing wheel valves, and washers are checked to ensure they are in a satisfactory working condition and that the inlets and outlets are compatible with fire service equipment and readily accessible. Where necessary, washers, blanking caps and straps etc. will be supplied and fitted at the time of the test (at an additional charge) to comply with British Standard.
In addition, all valves will be worked, outlet-sealing washers will be inspected and the operation of lugs, non-return valves and air valves will be checked
Only a flow and pressure test can confirm that water will be delivered as expected when the riser is called upon in an emergency.
The test carried out by Norfolk Fire Service ensures that, in addition to the static pressure test, where two jets are operating from the top, or furthest outlet, a running pressure of 2.5 bars would still be available in the system.
These covers may be found in the footpath roadway or in the verge. Marker plates can be seen fixed to a post or wall or lamp post.
Norfolk Fire and Rescue Service have approximately 22,000 Fire Hydrants spread throughout the county. It is our responsibility to ensure that these Hydrants are kept serviceable and available for use in the event of fire.
All public fire hydrants are subject to routine inspection and testing carried out by Norfolk Fire & Rescue Service. This includes:
Above ground inspection
The Hydrant frame, and cover, and the surrounding surface is checked for damage. The hydrant marker post is checked to see if the information shown is correct and is clearly visible. Any overgrowth is cut back and post and lid and kerb may require re-painting.
Below ground inspection
This Involves checking the Hydrant pit and the Hydrant itself. It is checked for leakage, the pit itself may require clearing of silt or debris which may affect the delivery of water for fire fighting purposes. The hydrant is also ‘wet tested’ to ensure the hydrant is working properly. They may also be tested for water pressure and flow.
Hydrant marker posts or plates help firefighters to quickly identify the location of fire hydrants, sadly these occasionally get vandalised or damaged. When missing or obscured it could waste valuable minutes in locating a hydrant and could potentially cost lives or increase the amount of damage in a fire.
We encourage contact from the general public in relation to problems or enquiries about fire hydrants. Reports of any damaged /leaking fire hydrant or related equipment is inspected and repaired as soon as possible.
A fire hydrant marker post is yellow and the manhole lid should be marked with the letters 'FH'. Concrete colour posts with a blue identification plate are the responsibility of the water authority.
If you spot a problem please complete the hydrants defect form or contact 0300 1231165.
In the event of fire, it is vital that firefighters have access to water supplies quickly. Obstruction of fire hydrants, particularly inconsiderate parking, could place the lives of you, your family, your neighbours and your business continuity at risk.
A person commits an offence if they damage or obstruct a fire hydrant, and is liable to prosecution (Fire and Rescue Services Act 2004 section 42). This includes parking where it obstructs a fire hydrant and prevents access for fire fighting use.
It is illegal to use a fire hydrant to obtain water for purposes other than fire fighting (unless authorised by the Water Authority or other person to whom the hydrant belongs). Unauthorised access to the hydrant pit is not allowed. Persons found to be using fire hydrants without the appropriate authorisation are liable to prosecution.
Please contact the Water Officer by email water.officer@fire.norfok.gov.uk or call 0300 1231165 if you are concerned that a hydrant is being used illegally or regular inconsiderate parking is occurring over a hydrant.
On occasions, fire hydrant markers may need to be relocated, for example, when a property owner wishes to remove a boundary wall. If you wish to relocate a hydrant marker, please contact the Water Officer by email water.officer@fire.norfok.gov.uk or call 0300 1231165.
When a new development within the county is planned, Norfolk Fire and Rescue Service will determine the risk and recommend the number and position of any fire hydrants required. Each hydrant is strategically placed, to ensure the minimum provision is made, whilst delivering the optimum supply of fire fighting water delivered from a mains system. Alternative water supplies are taken into account when assessing the overall requirements.
Please contact us for more information, for developments affecting or requiring fire hydrants in Norfolk.
Private fire hydrants are located on water mains that are not owned by, or the responsibility of, a water company such as Anglian Water. These are generally located on large sites such as hospitals, military establishments, and industrial estates, but may also be installed to provide cover for specific risk properties. Private hydrants are the responsibility of the owners/occupiers on whose land they are installed.
Private hydrants should be installed in accordance with the appropriate British Standards and should be compatible with Fire and Rescue Service equipment.
Where private hydrants are installed they should be maintained in good working order by the responsible person(s). They should be inspected and tested in accordance with relevant British Standards, especially if they have been identified on Norfolk Fire and Rescue Service Risk File information sheets and the responsible person has identified them as a reliable water source for fire fighting.
Norfolk Fire and Rescue Service offer a service to maintain and test these private hydrants.
