What are the benefits to the Concept Tank™ Solution?

Our innovative solution provides greater benefits compared to traditional storage methods.


Concept Tanks adheres to the strictest safety protocols during every stage of construction. All tanks are well engineered and lined using NSF 61 certified Enviro Liner® geomembranes.


Concept Tanks™ offer a superior solution over traditional fluid storage methods by significantly reducing the environmental impact on the immediate and surrounding area.

Fast Installation

Due to its unique, modular design, Concept Tanks™ have rapid installation times, giving greater flexibility to project timelines.

Minimal Earthworks

Our tanks sit on a 30% smaller footprint than traditional solutions and only require a hardened earth pad foundation, requiring minimal earthworks and remediation works.

24/7 Remote Monitoring

Concept Tanks offers remote monitoring through its back-to-base SCADA software, allowing asset maintenance teams to monitor plant function and schedule maintenance.

Cost Savings

Concept Tanks experienced field team and patented design allows for 75% faster construction at up to a 40% lower cost over alternative solutions.

Case study

4MG Concept Tank™ – Refinery Process Liquids

This case study describes a challenge at a site where valuable process fluid was being lost to a tailings dam during shutdowns, causing revenue loss and environmental concerns. The client initially considered constructing a lined earthen pond but dismissed it due to cost and environmental issues. The solution involved prefabricating two Concept Tanks off-site, reducing permitting time, and enhancing leak detection and containment monitoring. The tanks were quickly installed, minimizing disruptions and improving safety, and are now being expanded to alleviate further pressure on the tailings storage facility.

3MG Concept Tank™ – Dust Suppression

Concept Tanks was engaged by a client to develop a solution to complex dust suppression requirements in remote Western Australia. This Pilbara-based project saw our in-house design team solve various environmental concerns through an innovative Concept Tank™ and cover design. The walls of the 3 Million Gallon Concept Tank™ were raised to keep local fauna out, and the tank was equipped with a satellite leak detection system to keep operators informed remotely. A floating cover was also designed and installed to protect from seed and dust contamination.

The project took 2 months to complete, leading to significant cost savings for Monadelphous while remaining environmentally friendly.

Case study

15MG Concept Tank™ – fluid storage

A client engaged Concept Tanks to assist with fluid storage for its operation in Australia, producing natural gas for domestic supply. The complex natural gas project required an immense 30 Million Gallon brine storage solution, which Concept Tanks was able to deliver quickly and efficiently.

The Concept Tank™ solution involved deploying two 15 Million Gallon modular concrete tanks in just two months. The Concept Tank™ system was designed with various safeguards for the harsh conditions of the region. The double-liner featured water tube ballasting to ensure liner integrity at any water level; a must when dealing with evaporation in extreme climates. Radar level sensors are monitored remotely, and a sealed poly sump provides added durability compared with conventional options.
