Every underground fuel tank in Australia is a legal liability. WetTrack automates your monthly Statistical Inventory Reconciliation so you stay compliant, avoid fines, and protect your licence.
Underground storage tanks at fuel retailers, transport depots and industrial sites contain millions of litres of petroleum products — and are subject to strict federal and state regulation.
An Underground Petroleum Storage System (UPSS) includes the tanks, pipes, fittings and dispensing equipment used to store and transfer fuel below ground level.
Any leak — even a small one — can contaminate groundwater and soil over vast areas. The EPA mandates monthly Statistical Inventory Reconciliation (SIR) to detect losses early.

What Operators Say
TRUSTED BY FUEL OPERATORS ACROSS AUSTRALIA
★★★★★
Before WetTrack we were doing SIR in Excel. It took two days a month and we were never sure if we'd done it right. Now it takes ten minutes and the EPA report is already formatted.

Michael R.
Operations Manager · Metro Service Station, VIC
★★★★★
We had an EPA inspector arrive unannounced last quarter. Because we had WetTrack, I was able to print the last 12 months of SIRA reports in under 5 minutes. Inspector left satisfied.

Director · Northside Fuel Depot, SA
★★★★★
We manage 14 sites across WA. WetTrack's multi-site dashboard means our compliance team can monitor every tank in one place. The bulk discount for 5+ sites is a real saving too.
