This tank is ideal for storing drinking water when a backup drinking water reservoir is required, such as during renovations/development work, when water is supplied from a private borehole or spring or in other cases where mains water supply is limited.
 
Storing drinking water in an underground tank protects it from extreme heat or cold weather and is great when space for an above-ground tank is limited.
