Grey Water Tank Uses and Applications

Large Storage Tanks: Large Gray Water Pillow Tanks are an ideal choice for any location dealing with temporary bulk liquid storage. Often used on frac sites, irrigation areas, mining fields and commercial locations, these tanks offer increased storage potential in a single storage unit. In addition, all tanks are also able to be quickly folded for transportation to and from locations. This reduces shipping costs and makes eases transportation requirements.

Small Gray Water Tanks: For smaller storage requirements, small pillow tanks can can offer low profiles and flexible sizing options. Most small tanks feature a filled height of two feet (2') or less. This allows them to be stored in tight or low profile areas where a more rigid tank would not fit. It also allows them to easily fit through doorways or frames.

Custom Storage Tanks: Flexible tanks are also well-adapted to custom requirements. While many tanks are offered in standard or typical sizes, we are also able to accommodate custom storage requirements including extended dimensions, low profiles and unique storage requirements.
