Commercial and residential properties that do not have an adequate water supply for local authority requirements can be supplied with a water storage tank for a building permit. Fire protection water tank capacity size is based on local fire authority requirements and building size and location. The local Fire Marshal will typically delegate the water tank capacity requirements but a fire protection engineer may be consulted as well. Our full lines of firefighting nozzles and adapter options can turn your tank into a water source that is ready for emergencies.


Fire sprinkler systems use on average eight gallons-per-minute which an estimated fire flow need of two sprinklers running at a minimum of 7 – 10 minutes. We can supplement or create an existing water supply for a fire sprinkler system for commercial and residential buildings.
