Oil Storage Tanks
7-1.1 Size and Siting of Tank
The size and site of the tank should be chosen to be least obtrusive with consideration to
the following:-
1.
Access for fuel delivery vehicles.
2.
Distance of tank from the road. Most delivery vehicles can deliver up to 30m.
3.
To obtain discounts on fuel it is normally required to purchase a delivery of 500
gallons (2,300 ltrs.), therefore a 2,500 ltr. tank is ideal.
7-1.2 Plastic Tanks
Plastic tanks are normally placed at ground level. A smooth flat surface supporting the
tank across the entire base surface is all that is normally required.
7-1.3 Steel Tanks
Steel tanks should be supported above ground with brick or block piers. A waterproof
membrane should be included under the tank.
Notes
Check with oil supplier for access
requirements.
Refer to Appendix, page 65 for required
standards for oil tanks.
