Things to take into account when installing a cold water storage cistern

Factors to consider when deciding where and how cold water storage cisterns are installed include but are not limited to:

• whether the distributing pipework (system) is pumped or supplied by gravity

• the need to allow for ease of access for maintenance • inspection (both internally and externally)

• cleaning requirements

• environmental factors which might affect water quality such as excessive heat gain or the likelihood of flooding.

Float operated valves and other controls should be readily accessible. There should be sufficient clearance to allow for inspection, cleaning of internal surfaces and maintenance.

Cisterns with a capacity greater than 1,000 litres should be capable of being inspected and cleansed without having to be wholly uncovered.

To avoid distortion cold water storage cisterns should be adequately supported. Advice on how to do this can be found in Part G of the Building Regulations.

Please note: In many cases the local water undertaker will need to be given advanced notice of the proposed installation of any cold water cistern. This is an important simple and essential check to minimise the risk to water supplies.
