Highland Standard Dike Tank

Diked tank with 110% secondary containment

Highland Dike Tanks are a versatile aboveground secondary containment alternative. The impervious steel dike contains spills from the tank, piping and associated equipment, and it prevents their release into the environment. Available in single or multi-tank modules, Dike Tanks are easy to install and relocate if necessary. Both tank and dike are product compatible and possess the strength and impermeability of steel. They are ideal for the secure storage of petroleum, chemicals, hazardous wastes, fertilizers and more.

Description

Highland Dike Tanks consist of a saddle-mounted UL-142 steel tank, secured in the center of a steel containment dike, engineered to safely contain 110% or 150% of their largest tank’s capacity. Our standard dike includes fittings for water control.

Both tank and dike are elevated on supports to allow visual inspection of the exterior bottom surfaces. Tank-to-dike hold-down systems vary with capacity.

The entire unit meets UL-142® and NFPA 30 specifications for primary and secondary containment. In addition to our standard features and options, we can also supply rain shields, gabled-end, shed-style or rolled-top canopies to keep out rain, snow and debris.

AREO-style Dike Tanks are also available with a unique rain shield system preventing water and debris accumulation in the containment dike while making provisions for visual monitoring.

Options

  • For added protection, custom fit rain shields are available to keep out rain, snow and other elements.
  • To completely cover the dike and tank, Highland manufactures the Rolled-Top Dike Canopy. Designed and engineered ladders, platforms and walkways are available to customize a dike tank to your specific needs.
  • These options can be fitted to the inside and outside of the dike and the outside of the tank.
