Polyethylene tanks are commonly specified for liquid storage because they resist corrosion and are available in a wide range of footprints. We supply poly tanks in vertical, horizontal, leg, double wall, rectangular open top, and cylindrical open top configurations for water storage and many general liquid storage needs. For engineers, facility managers, operations teams, maintenance leads, and safety and environmental staff, the fastest path to the correct selection is to start with the process conditions and then define the geometry, access, and connection plan.
Begin with the stored liquid, concentration when applicable, and service temperature. Confirm the design load using specific gravity at operating temperature. Then select the tank style that fits the available footprint and required access. Connection planning is usually the deciding factor during quoting, so define each nozzle function, size, and exact location early.
If secondary containment is required by policy, code, or site standards, specify a double wall configuration at the start. Double wall tanks are commonly considered where secondary containment requirements apply. Depending on the application, relevant standards may include EPA secondary containment rules under 40 CFR 264.193. If mixing, manual additions, washdown, or frequent inspection is expected, specify an open top style or confirm manway size and placement for a closed top tank.
