What makes a water tank potable?

The difference between a potable water tank and an ordinary water tank is that potable tanks store water fit for human consumption. For a potable water tank to be classified as fit for storing consumable water, it has to meet several WRAS requirements to ensure the water is safe for drinking.

How long does potable water last in a tank?

Drinking water should only be left to sit in a potable water tank for six months at a time. The water inside the tank should be drained and replaced after this period. To preserve the potability of the water, the internal temperature of the tank should be from 10–21°C to prevent bacterial growth.

How often should potable water tanks be cleaned?

Your potable water tank should be inspected and professionally cleaned at least once a year. If any previous inspections of your tank reveal bacterial contamination, your tank should undergo maintenance more regularly.
