Bund Water Control Unit

A bund is a secondary containment enclosure constructed around oil (or chemical) storage facilities to prevent leaks and spills from contaminating watercourses. The effectiveness of bunds relies on their watertight design, which leads to the accumulation of rainwater. This rainwater becomes tainted due to everyday drips from the storage facility. It is crucial to remove this polluted rainwater in an environmentally responsible manner to maintain the bund's full capacity for containing significant spills and to prevent oil pollution incidents.

Aquasentry's Bund Water Control Unit serves as a de-watering system designed for areas where rainwater mixed with oil residues can accumulate. This innovative system operates by detecting the distinction between oil and water, then efficiently pumps out the water into the surface water drainage system or a designated soak away area. It achieves a remarkable water removal rate of 145 litres per minute, resulting in a discharge rate of less than 5mg of oil per litre (equivalent to 5 parts per million). This exceptional performance makes the Bund Water Control Unit both safe and highly effective for its intended purpose.

Using conductivity probes, the unit determines the liquid's composition within the sump and triggers the pump to initiate water removal. Once all water is eliminated and only oil remains, the pump automatically stops. This process contributes to cost-effective and efficient waste disposal while safeguarding the bund from deterioration.

Operating tirelessly 365 days a year and 24 hours a day, the unit maintains your bunded area in optimal condition, ensuring it remains dry and free from oil contamination. These units find application in various scenarios, ranging from sub stations and oil bunds to underground lift shafts. They are also adaptable for use within zoned areas.

With the Aquasentry Bund Water Control Unit, your bunds consistently retain their specified 110% capacity, as outlined in PPG 2 regulations. This cutting-edge solution offers a cost-effective approach to de-watering, establishing a best practice standard for the environmental management of your bunded areas.
