BMS manufactures a large range of Fire Fighting Holding Tanks from 1,000 – 100,000 L including Steel Framed Tanks suitable for partial/fully above ground installation.  All Fire Fighting Tanks are manufactured under an NSAI Verified ISO 9001:2015 Quality Management System.


How Do They Work?

Fire Fighting tanks are installed in areas where there may not be access to sufficient water/mains water pressure to fight a fire.  BMS tanks provide a large water holding capacity and can be used by Fire Fighters as a supplemental water source in the case of a fire.  They are frequently specified as a condition of planning and can also form part of an onsite surface water management or SuDS system.

BMS Fire Fighting Tanks are normally full unless being cleaned out or used for fire fighting purposes.  If part of a surface water management system, water in the tank should turn over in conjunction with rainfall.  BMS recommend a BMS Petrol/Oil Interceptor or Stormbreaker Defender should be fitted before the tank to remove any Petrol/Oil/Silt/Grit.  If supplied by mains water, an automatic ball valve can be fitted to top up the tank if the level drops.  Alarms can also be added to alert of high or low water levels in the tank.  These alarm systems can send out alerts via a GSM Dialout System and can even be powered by solar panels.


As with any tanks regular inspection is required to check for adequate water levels and to check water quality.  It is recommended that the water in the tank is changed over on a regular schedule if the tank is not connected to the surface water drainage system.


BMS Fire Fighting Tanks are delivered ‘ready to go’ with pipework to match those on site.  Installation generally involves digging a suitably sized excavation, placing the tank on a 20 N slab, connecting the inlet/outlet pipes and then back filling with a full 225 mm lean mix surround while counter filling the tank with water. If the area over the tank is going to be traffic loaded an appropriate non weight bearing slab should be constructed over it.  Full instructions are available.  A steel framed GRP alternative is available which can be placed fully above, partially below or fully below ground without a concrete surround.
