Ultra-Self Bailer

Passively filter hydrocarbons from stormwater in outdoor containment products

The challenge of outdoor spill containment lies in the presence of rain—a factor not encountered indoors. When rainwater accumulates in the containment unit’s sump, it compromises the unit’s ability to effectively contain spills. Essentially, for each gallon of rainwater collected in the sump, there is a corresponding reduction in the capacity to contain chemicals, fuels, or hazardous materials.

Addressing this issue is the Ultra-Bund Accessories Self-Bailer. This accessory is designed to seamlessly attach to any spill containment unit, usually through a bulkhead fitting. It allows rainwater to drain through while filtering out any residual oil, gas, or hydrocarbons, ensuring that only clean water is released. In the event of a spill, the self-bailer activates, sealing off completely to prevent any liquid from escaping.
