This oil or fuel may be stored in tanks at depots or terminals or inside transformers at sub and transmission stations. In most cases however, the vessel holding the oil is contained in an unroofed bunded area.

Bunds are constructed to act as a safe guard against events such as tank ruptures or transformer failures. Without bunding, pollution or ground water contamination risks are high.

Unfortunately in most cases, bunds also collect storm water. The legislation covering discharge of water from bunded areas is, and only ever will, become more stringent. Presently in most states and countries, to prevent the possibility of accidental drainage of potentially contaminated water from bunds, it is not permissible to install drain valves.

Bunds do not only guard against major catastrophes. Minor spills, leaks or drips which can occur when filling or emptying such vessels will often result in contamination of water in bunds to levels well in excess of discharge standards.

The solution to the management of storm water collected in bunds is either evaporation, or treatment. Evaporation obviously is the low cost option, however, during high periods of rainfall the effective bund capacity will be greatly reduced. Also, as optional health and safety requirements prohibit work being conducted in wet areas, bunds containing water can delay commencement of maintenance or emergency work.

The AJM EnviroSEP™ is the most practical method for removal and treatment of water whilst constantly maintaining a dry bund.
