You can supply drinking water from a storage cistern provide you take account of a few things. In the UK water regulations, Clause R27.2 It states that wherever practicable drinking water should be supplied direct from the mains. However you can use a cistern if
a. The interior of the cistern is kept clean.
b. The quantity of water stored is restricted to a minimum essential capacity so that throughput of water is maximised.
c. The water is kept below 20C
d. It has all the relevant parts from the byelaw 30 kit
e. The cistern is regularly inspected and cleaned internally
Depending upon where you live and given that the cistern must be insulated it can be difficult in summer to keep the water below 20 degrees whilst also preventing freezing in winter.
Ultimately as others have stated, it is much more preferable to have the drinking water off the mains but it can be done when there is no other alternative.
