Bund Water Control Unit || SKU: 1000549 || MPN: PQ-025G || Brand: Darcy
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.

A bund is a secondary containment system that serves the purpose of capturing any leaks or spillages from a primary containment, such as a storage tank. It is composed of an impermeable floor and a set of impermeable walls, creating a watertight area around the storage tank. The bund effectively retains any liquid that escapes from the primary containment, preventing it from spilling onto the site or escaping into the environment.
Bund maintenance often overlooked, but it crucial for the longevity and effectiveness the infrastructure. Over time bunds wear and become unfit for their if not properly maintained.ing a maintenance and inspection is important to identify necessary repairs prevent further damage.
An effective bund should collect and contain all substances that enter it, including rainwater and other unwanted debris. Neglecting proper maintenance can lead to a build-up of unwanted materials, reducing the bund's capacity and potentially causing it to fall below requirements. It is essential to regularly remove rainwater and test it for contamination before disposing of it. Contaminated water must be disposed of in accordance with waste regulations or treated using appropriate control measures. For oil bunds, automatic bund water control units can be installed to separate oil and water, pumping out only the water.
In addition to regular rainwater removal, periodic inspections should be conducted to assess the condition of the bund walls, floor, penetration seals, and linings. Any defects or damage should be promptly repaired to prevent further deterioration. Even minor cracks can lead to liquid leakage, and structural issues can significantly weaken the bund walls, risking failure under dynamic loads. Hydrostatic testing, filling the bund with water and monitoring for any loss, can also be performed to determine if the bund is watertight.
If a bund experiences any issues, it is crucial to address and fix them promptly. Defective bunding can be even worse than having no bunding at all, as it can mask leaks and create a false sense of security. Over time, chemicals or oil leaking from faulty bunds can cause serious contamination of the surrounding ground and groundwater. Cracked bunds need to be repaired to ensure not only water-tightness but also structural integrity to withstand potential catastrophic failures. If the bund lining fails, relining or patch repairs should be undertaken.
