Cold water storage

P​rotecting cold water storage cisterns from frost damage

To minimise the risk of damage due to freezing all cold water storage cisterns, including any associated pipework which may be at risk, should be protected. The type and level of protection will be dependent on the environment in which the installation is located.



In premises where there will be water demand or a positive change to the ambient temperature within 12 hours, the insulator calculator can be used to give an indication of insulation requirements. Where this is not likely to be the case the local water undertaker should be consulted as insulation alone may not be suitable.
