To answer the question first we need to establish the usage of the cold-water storage tank. Typically, there are two types of systems that would be used when a cold water storage tank has been fitted - a Boosted Cold- Water Supply (BCW) or a Cold Water Down Service (CWDS) supply. Boosted Cold Water (BCW) is required when the cold-water storage tank is located at a low level in a building and water needs to be pumped upwards for distribution. A BCW system typically comprises a cold-water storage tank that supplies a number of pumps that distributes the water around the building to the various water outlets. As the stored water is being used for all services including drinking water, (Potable) the cold-water storage tank will need to be inspected every 6 months and disinfected on an annual basis as recommended by the Drinking Water Inspectorate. Cold Water Down Service, typically the cold-water storage tank, is located generally in the roof or loft space. In most cases this storage tank will provide cold water to toilets and hot water service, but in some properties all of the cold-water taps may be fed from this tank, but is not intended to be provide drinking water (Non-Potable). Drinking Water would be supplied direct from the main water supply and would be usually identified via a label. The table provides guidance on the recommend frequency and maintenance that would normally be undertaken, but site-specific guidance should be obtained from the site risk assessment.

Retain records of any monitoring inspection, test or check carried out, and the dates, for at least five years. Water Monitoring Records - How long should we keep them?
