A Consistent 1,750-Litre Bunded Waste Oil Tank Specification Across Four Orders
Repeat Precision: Deploying the Imperium 1,750L Steel Bunded Waste Oil System

When managing multi-site operations or expanding facilities, securing consistent, high-specification fuel and waste storage is essential. A repeat tank requirement is not merely about reordering the same vessel—it is about guaranteeing that capacity, socket connections, level monitoring, and logistical offloading remain identical from one order to the next.
Recent sales records highlight four separate orders fulfilled for a major commercial client, each specifying the TAN.WOI-1853 Steel Bunded Imperium® Waste Oil System. Accompanied by integrated level monitoring and our specialized HIAB delivery, this project demonstrates how standardized equipment specifications simplify procurement and installation across multiple locations.
Project Snapshot: Standardized Repeat Scope
Having a reliable, repeated specification provides purchasing managers, site engineers, and installation teams with a trusted baseline. The table below outlines the core parameters repeated across all four deployments:

| Logistics Package | Premium White Glove Delivery Service with HIAB crane offloading |
Engineering Features of the Imperium® Waste Oil Tank
The TAN.WOI-1853 is the dedicated waste-oil variant within Atlantis Tanks’ modular Imperium® steel range. Engineered specifically for controlled, spill-free fluid management, the unit offers several tailored operational features:
1. Manual Disposal & Extraction Ports
- Integral Strainer & Lockable Lid: Designed for secure, controlled manual pouring of waste oil while capturing debris before fluid enters the inner tank.
- Top Suction Drain Port: Equipped with an internal suction standpipe, providing a dedicated, clean extraction path for vacuum tankers during routine waste removal.
2. The Imperium Removable Access Plate
A signature design aspect of the modular Imperium® range is its removable front fittings plate. This feature simplifies inspection of connections and allows for straightforward modification or retrofitting of gauge equipment and optional lockable top boxes in the future.
3. Integrated Secondary Containment
Constructed from high-tensile S275JR structural steel, the outer bund provides 110% capacity relative to the inner vessel, ensuring strict adherence to environmental protection regulations and preventing ground contamination risks.
Complete Environmental Monitoring Suite
To ensure maximum operational safety and prevent accidental overfills, each order was supplied with a comprehensive monitoring package:
- Apollo Ultrasonic Contents Gauge: Features a tank-mounted transmitter that continuously monitors fluid levels and wirelessly transmits data to a remote plug-in receiver.
- Battery High-Level Alarm: Features an internal 5-metre probe coupled with a high-decibel (90 dB) audible sounder and a flashing red LED indicator to give clear visual and acoustic warnings during filling operations.
Integrated HIAB Logistics and Turnkey Delivery
Offloading heavy steel tank assets requires dedicated equipment. Every order in this series included our Premium White Glove Delivery Service, ensuring transport on specialized Atlantis vehicles fitted with HIAB crane offloading apparatus. This service allows the tank to be safely offloaded from the vehicle bed directly to the prepared site base, minimizing downtime and third-party crane hire costs.
Compliance and Site Standards
While the Imperium® tank is manufactured in strict alignment with BS 799 Part 5 standards and offers 110% secondary containment, site-specific installation compliance remains essential. Environmental guidance dictates that site managers verify ground conditions, bund clearances, and local building codes before placing any waste oil system into active service.
“Standardizing tank specifications across multiple facilities ensures seamless procurement, identical connection layouts for engineers, and consistent environmental compliance across every operational site.”
