Static Water Storage

Building Code of Australia

The Building Code of Australia requires a static water storage – a secondary water supply storage in buildings over 25m in effective height with conditions to provide the water supply for the buildings sprinkler system. The building surveyor/ building certifier will nominate the static water storage system in the essential safety measures determination/ schedule.

Part E1 Fire Fighting Equipment, clause E1.5 Sprinklers, refers to Specification E1.5 Fire Sprinkler Installations, clause 7 sets out the criteria of the water supply requirements for a sprinkler system and when a static water storage can be used.

Essential Safety Measures Audit – Static Water Storage

An essential safety measures auditor should check the essential safety measures determination/ schedule to ascertain whether a static water storage system is nominated. A regular inspection should be performed. A static water storage system would most certainly incorporate a water pump set, the auditor should ensure maintenance is carried out in accordance with AS 1851-2005 Maintenance of fire protection systems and equipment. Any defects noted during the inspection of a static water storage should be recorded in the building’s essential safety measure logbook to allow the signing of the Annual Statement, Annual Certificate Compliance, Annual Fire Safety Statement, Annual Maintenance Statement and Annual Occupiers Statement.
