Aboveground Storage Tank (AST)

An aboveground storage tank (AST) is a liquid storage system installed above the surface rather than underground. In industrial operations, ASTs are commonly used to store freshwater, wastewater, frac water, produced water, cooling water, process water, sludge, and other commercial liquids.

Industrial AST systems are widely used because they support large-volume storage while allowing easier inspection, monitoring, maintenance access, and temporary deployment compared to many underground systems. Many AST systems are modular, allowing capacity to scale based on project requirements.

WWS uses modular aboveground storage tanks across oil and gas, industrial wastewater, manufacturing, agriculture, food processing, construction, and infrastructure projects throughout North America.

Common AST applications include frac water storage, industrial wastewater containment, cooling water storage, sludge holding, dewatering projects, and municipal bypass operations.
