Dry and wet risers are fixed fire fighting systems, used by the Fire Service in the event of a fire. Dry risers are generally found in buildings between 18 and 50m in height. However, buildings less than 18m in height, may also have dry risers. Any buildings over 50m in height will have a wet riser installed.
It is crucial that these riser systems are in good working order at all times and that their location clearly signed as they are used by the Fire Service to direct water to the fire quickly and effectively.
As experienced Fire Service Professionals, our team are best placed to make sure that your premises are ‘emergency-ready’ – including updated signage and navigation.
Adena Fire will ensure that your systems comply with BS9990:2015.
A dry riser is a system of pipework and valves running through the height of a building, allowing the Fire Service to deliver water to a fire located on any level of a building. They are generally found in buildings over 18m in height.
BS9990:2015 – requires that dry rising mains are visually inspected every six months and that wet-pressure tests are conducted annually (which includes the visual inspection).
Wet risers are similar systems to dry risers, but are permanently charged with water and are generally found in buildings over 50 metres in height.
BS 9990:2015 requires that wet rising mains are visually inspected every six months. The pumps must also be tested and serviced on an annual basis, in addition to conducting pressure and flow tests. It is imperative that all risers are tested and maintained on a regular basis to ensure that they are ready for use by the Fire Service at all times.
In the light of Grenfell and the subsequent changes to fire safety requirements, it has been recommended that these lifts are tested regularly. This is to ensure that the lifts are ready for use in high-rise buildings in the case of fire.
When conducting dry riser testing and maintenance, we often found that the risers were difficult to find on the external face of the building – potentially causing vital minutes when the Fire Service attends a fire. Therefore, we now provide guidance on making sites ‘Emergency-Ready’ by providing recommendations for signage which we can add around your site.

Adena did the testing and commission on the new wet riser at Edward Wood and did a fantastic job. Gary asked me about our servicing and I said I would definitely pass on his details.Billy Reid Head of Mechanical & Electrical The Economy Department LB Hammersmith & Fulham Council
