The challenge

The second of three mega-scale Concept Tanks™ was installed at an onshore natural gas production facility to provide additional produced water storage. The hyper-saline water is a byproduct of gas operations and requires a high level of containment to prevent contamination of the surrounding environment.

These Concept Tanks are part of a scaled approach to the operator’s water management process, reducing upfront capital expenditure and aligning storage capacity with water production.

The solution

Utilizing these larger-scale Concept Tanks significantly fast-tracked the client’s permitting and construction process, enabling the client to commence gas production activities. The three 475-foot (144.7 m) diameter tanks are comprised of four liner layers: two Enviro® Liner geomembrane layers, a geotextile layer and a Geovolt® conductive composite, which is an intermediate layer enabling spark testing of the liner prior to filling the tanks with fluid.

These Concept Tanks are outfitted with continuous monitoring systems for precise tracking of water levels within the tanks and early detection of potential leaks. This advanced monitoring capability is a critical asset in the storage of contaminated fluids, especially in remote and isolated sites.

Each Concept Tank took four weeks to construct, with minimal ground disturbance and earthworks for the tank pad. The tank systems have a 25-year design life and are relocatable.
