Self Bunded Diesel Tanks — AS 1940 Compliant Bulk Storage

Self-bunded diesel tanks deliver AS 1940 compliant above-ground fuel storage without a separate bunding structure. The double-wall design integrates secondary containment directly into the tank — the outer wall captures any fuel from the inner tank, holding a minimum of 110% of its capacity. From 1,000L portable units to 115,700L bulk installations, Fuelgear has the right self-bunded diesel tank for your site.

Overview

What Are Self Bunded Diesel Tanks?

Self-bunded diesel tanks — also called double-wall diesel tanks — are above-ground fuel storage vessels with integral secondary containment. The outer steel wall surrounds the inner fuel-holding tank, creating an enclosed annular space that captures any leakage and contains a minimum of 110% of the inner tank's total volume. This construction makes self-bunded tanks AS 1940 compliant for above-ground diesel storage in Australia without requiring a separate concrete or steel bunding structure to be constructed on site.

Available from compact 1,000L portable skid tanks right through to large 115,700L bulk storage units, self-bunded diesel tanks are deployed across mining, agriculture, transport, construction and industrial applications throughout Australia. They are the go-to solution for sites where installing a separate bunded compound would be impractical, cost-prohibitive or time-consuming — particularly on remote mine sites, large agricultural properties and temporary construction compounds.

Key Features

AS 1940 compliant — meets Australian Standard for the storage and handling of flammable and combustible liquids
110% integral secondary containment — outer wall captures leaks without a separate bund structure
Wide capacity range — 1,000L to 115,700L to suit every site from small farms to large industrial operations
No bunding civil works — reduces site preparation cost and lead time significantly
Skid-mounted and relocatable — forklift pockets allow repositioning as operational needs evolve
Pump, filtration and level gauge options — fully configure the tank system for your dispensing requirements

Selecting the Right Self Bunded Diesel Tank

Application	Recommended Product	Key Consideration
Small farm or construction compound	1,000–5,000L self-bunded tank	Compact; forklift-movable; immediate AS 1940 compliance
Agricultural property or transport depot	10,000–30,000L self-bunded tank	Most cost-effective bulk storage for mid-volume operations
Mining operation or industrial site	50,000–115,700L self-bunded tank	High-volume reserves; integral containment avoids civil bund
Immediate dispensing required	Self-bunded tank with pump package	All-in-one system — pump, meter, hose reel included
Remote or unmanned site	Self-bunded tank with level monitoring	Telemetry and alerts for fuel level management from distance
Temporary site with future relocation	Skid-mounted self-bunded tank	Forklift pockets; fully relocatable without losing compliance

Key Benefits

Why Self Bunded Tanks Are the Australian Standard

Compliance & Cost Benefits

AS 1940 compliance from delivery — no waiting for bund construction, concrete curing or inspector sign-off
Eliminates bund construction cost — saves thousands in civil works on sites where bunding would otherwise be required
Protects against EPA penalties — integral containment meets environmental regulations for diesel storage across all Australian states
Fully relocatable asset — move the tank when the project ends rather than abandoning fixed infrastructure
Scales with your operation — add additional self-bunded tanks as fuel demand grows without expanding bunded compounds
Reduces insurance risk — secondary containment demonstrably reduces environmental liability exposure
