CEMO 980 Litre Diesel Mobile Storage Tank
This guide provides advice on how to install your JSM diesel tank. Much of this detail is appropriate by most jurisdictions, however the installer is responsible for ensuring local authority requirements are met.
Tank design & detail
The tank has been designed and manufactured in compliance with AS/NZS 1692: 2006.
Each tank has the following features:
- 50NB Filling port centrally located on the top
- 25NB Ventilation port
- 10NB Outlet port on the bottom
- 40NB Plugged port on top for additional features
- Restraint tabs
- Feet with bolt-down holes

The most common requirement for installation of the tanks is that they are installed compliant to AS 1691:1985
Bund or no Bund
A bund, in simple terms, is a secondary containment surrounding the tank. If the tank leaks, the leak will be contained by the bund. Our bunds are manufactured from galvanized steel and include a cover that prevents water filling the lower bund that surrounds the tank. It’s not very common for the tank to be damaged or punctured, but sometimes spills occur when filling the tank. In these cases, the bund is intended to capture and contain any leaks. Most local Councils in New Zealand do not require secondary containment, or bunds – to contain any leaking fuel. However it is good practice to use a bund.
Stability, support and seismic restraint
Support & Restraint –
- The area of any footings that rest on earth, e.g. soil, clay, sand, or the like, shall not be less than 2cm2 for each litre of tank capacity.
- We recommend installing a concrete pad of 100mm thickness for masonry dynabolts or anchor fixing of the tank feet.
- Where the height of the centre of gravity of a tank above the foundations is more than twice the least width of the footings, the tank shall be provided with not less than two braces to a wall or similar structure.
Location and separation distances
Proximity to walls and boundaries –
- Distance (A) must be 20mm or more from masonry or concrete walls.
- Distance (A) must be 100mm or more from timber or other material walls.
- Tank may intrude into required minimum boundary setback distances by no more than 620mm. Or adjacent to a 90mm thick masonry or concrete boundary wall with a clear passageway of 500mm provided.
- Distance (E) must be 350mm or more for a 90mm masonry or concrete wall.
Proximity to building openings –
- Distance (B) to tank vents to be 1.0m or more from openings or windows.
- Tank must be more than 2.5m from any window of adjoining properties.
Proximity to building services –
- Distance (C) must be 1.8m or more from flue or chimney.
- Distance (D) must be 3.0m or more from fixed LPG storage tank or 1.0m from exchange cylinders.
Fill point access –
Distance from the parking position of a filling vehicle to the filler must be
45m or less (along an acceptable route for the filler hose must take).
Approvals
Requirements can vary from one public authority or agency to the next. Although this advice has been put together in adherence with current standards and codes of practice, these may not meet all of the requirements for your installation. Ensuring that local authority requirements are met is the responsibility of the installer – so check with your local council.
