Fire Sprinkler Water Tanks, otherwise known as firefighting water storage tanks, are designed to safely store water to feed fire sprinkler systems or for on-site firefighting water storage. Our fire water tanks are available with or without Fluid Category 5 backflow prevention.  Specific requirements of BS EN 12845 and BS 9251 for firefighting water storage should be closely followed too to ensure automatic fire sprinkler systems and fire protection systems are fit for purpose and meet the relevant requirements of industry standards and hazard classification.

Polyethene tanks have a distinct advantage over steel tanks as they will not rust and are very easy to maintain. Polyethene tanks are also very adaptable and can be fitted with numerous connection options to suit most installations.  Our water supply tanks for automatic sprinkler systems come in a wide range of tank sizes depending on the volume of water that is required.
