Water tanks for fire protection – some guidelines

In emergency fire fighting scenarios, the demand for water can exceed the supply available from the domestic water supply system. This is especially true for suburban or rural areas served by boreholes with limited and slow delivery capability (or malfunctioning municipal supply systems) and water tanks are an ideal solution for storing water for this purpose.

water tanks for fire fighting
Buildings like airfields, airports, schools, universities, hospitals, prisons, police stations, office buildings, data centres, and other institutional and commercial facilities need a reliable and redundant water supply – water tanks should be installed.

Consideration should be given to the type of water tank and its positioning.  Steel water tanks are more fire-resistant than plastic tanks and fibreglass tanks but their expensive and weight make steel water tanks less applicable to many situations in South Africa.  Polyethylene water tanks offer ease of installation and cost-effectiveness but must be protected from fire by positioning the water tanks in an area that has been cleared of vegetation and other flammable materials (i.e. a wide fire-break should be made around the tanks).

The water tanks can be fitted with pumps but ideally, gravity should be employed as fires may cause electrical shorts and outages.  This can accomplished by installing the water tanks on high water tank stands.  Steel water tank stands are also fire-resistant and tanks that are elevated 6 metres or higher will be protected from flames to a certain extent.

The capacity of the water tanks will depend on the size of the buildings/property that needs to be covered in the event of a fire.  A series of 10000 litre water tanks would usually be recommended, perhaps in two different locations.  Water from boreholes or other water supplies can be used to fill the water tanks but it is important to maintain the water tanks at full levels at all times.

Water tanks elevated from 6m to 9m will provide pressure for water bowsers to fill up with water beneath the tanks.  Any piping and fittings should be made from metal to prevent heat from interrupting water flow from the tanks.

As an alternative to installing water tanks up on tank stands, underground water tanks could be considered.  Being underground, these water tanks will be very well protected from fires.  A disadvantage is that some sort of pump (either at the tanks or using pumps mounted on water tankers) will need to be installed and in the event of a power outage, a back-up generator should be available for emergencies.  A series of underground water tanks placed at strategic points around a property would be advised.  A cost-effective, high quality underground water tank available in South Africa is JoJo Tanks’ 6000 litre underground water tank.
