A Bunded Oil Tank is a tank which is inside a tank. This ‘tank in a tank’ construction is also referred to as an integrally bunded tank. The outer tank is referred to as the bund and is required to hold at least 110% of the inner tanks brimful volume. Bunded oil tanks are required to be used for FUEL storage in the following conditions:
- Commercial / Industrial Applications
- Institutional Application
- Domestic installations where the installed capacity exceeds 2500L (unless suitably bunded – see Bunded Oil Tanks)
- Any Installation with a environmentally sensitive application as dictated by required
Bunded oil tanks offer protection from end of life failure of inner tank and overfilling of the tank during use; in the event of either of these conditions an alarm with sound and display light up warning that there is oil in the outer tank (bund). This warning gives the customer time to change out the tank or empty the overfilled oil without causing an environmental situation.
