Open Top Containment Pools

Open Top Containment Pools are an open style tank that fits easily under leaking valves, drums, tanks, storage vessels and machinery. Quick to move and easy to place, these tanks are one of the easiest ways to contain liquids in the event of a spill. Containment pools are frequently around facilities, pumping stations and other areas with the potential for small leaks or drips.

Containment Tank Construction

containment poolThe construction of the pop up containment pool creates an open top design that allows for easy placement under decon areas, leaking valves and decon showers. To create this quick containment system, built into each onion tank is self-rising foam collar that will allow the side walls of the tank to rise on their own as the system fills with liquid.

Pop Up Pool Design

While standard construction of these pools uses a high resistance 22 ounce PVC material, tanks can also be made with several additional fabrics or liners to meet the containment requirements of your location. If there is a specific liner or material needed for your location, please do not hesitate to ask!

For more information on these containment onion pools, please check out the following pages:

All containment pools feature a foam collar that provides quick assembly and easy transportation around your site. The design of the pop-up pools allows the tank to lie completely flat until it is filled with liquid. At this point, liquid fills into the tank causing it to rise and contain your materials. When not in use, tanks are compact and able to fit in storage vehicles for easy transportation around your site.
