60+ Years of Engineering Excellence in Tank & Storage System Manufacturing

For more than six decades, DEHOUST has been a trusted name in liquid storage and water management — engineering durable, code-compliant systems that protect water resources, reduce operating costs, and stand up to demanding industrial and commercial applications.

Precision-Engineered Polyethylene Tanks

Our HD-PE tanks and components are manufactured using advanced blow-molding technology and proprietary offline fluorination — a process that significantly improves chemical resistance, reduces permeation, and extends service life. This makes our tanks a reliable choice for fuel storage, rainwater harvesting, graywater recycling, and custom liquid storage applications across a wide range of industries.

Heavy-Duty Steel & Stainless Steel Tanks

Our steel tank construction draws on decades of manufacturing expertise, continuously refined for modern applications. We specialize in large-capacity single- and double-wall tanks — up to roughly 90,000 gallons (240 m³) — built in steel and stainless steel, as well as thermal buffer tanks for hot and cold water storage in commercial heating and cooling systems.

Water Quality & Backflow Protection

We also manufacture systems that safeguard potable water supplies, including backflow prevention assemblies (RPZ/reduced pressure zone) designed to meet stringent water safety standards.

Built for Sustainability, Built to Last

Whether you're looking to capture and reuse rainwater, recycle graywater for irrigation and non-potable uses, or store fuel and process liquids safely, DEHOUST delivers engineered solutions backed by rigorous European manufacturing standards and a growing footprint of certified products for the North American market.
