Water Storage

Guidelines for different model tanks

Standard tank

This tank is complete with internally flanged base, externally flanged side walls. All under water stays are stainless steel.


Suitable for indoor and outdoor use, and for the storage of foul water. These tanks have internally flanged lid panels, similar to those used in the base.



Suitable for indoor, outdoor use and for the storage of potable (drinking) water.



Standard tanks come complete with bolts galvanised to BS EN ISO 1464:1999, we recommend that consultants specify Stainless Steel grade 316 S16 bolts under water and on lid.


In any situation where there is only one water storage tank in a building and the capacity is greater that 1000 litres (220 gallons), BS EN 806 states “To avoid interruption of the water supply when carrying out repairs or maintenance, the cistern shall be provided with compartments or standby cistern”. Where drinking water is being stored, two separate tanks are recommended as it is difficult to detect cross contamination from one side of a division wall to another.


These should be used in any instance where condensation drips from pipework, or from the tank could cause nuisance damage or render floors wet and slippery.


Enclosed chamber containing an access hatch above the level of the cover, permitting the level control mechanism to be mounted at a higher level than would otherwise be possible. The overflow(s) must be placed on the tank side wall and not on the Ball Valve Housing. Water must be kept below tank roof level. This is only necessary where very large ball valves are used.


Where tank depth is 1m or greater, internal and external ladders should be specified. If the tank is on a raised platform then ladders may be required on tanks lower than this height. Where the tank is 2m or more from the top of the tank to the finished floor level external ladders should be fitted with safety cages and comply to BS 4211:2005+A1:2008. Guiderail: A guiderail should be fitted enclosing all access points to the tank roof, where a tank is 2m or more from the top of the tank to the finished ground level. Additional safety guards may be required for ladders depending on their location. A risk assessment should be carried out by the end users to determine if this is required.


(Externally flanged base) These types of tanks allow the tank to be totally drained down, as the base is flat, they also allow access to all the bolts from outside the tank. 600 mm clearance is required underneath the tank for access to the base bolts.



The client shall ensure that potable water is not stored in tank compartments that are adjacent to compartments storing foul water due to the risk of contamination.
