Flexible Tanks

Flexible Water Tanks

flexible tanksFlexible water tanks are an easy way to store small amounts of drinking water, rain water, greywater, and production water applications. Pillow tanks can be designed in capacities from 25 to 5,000 gallons in order to provide enough storage capacity for emergency applications, construction sites, and facilities.
All Mars flexible tanks are made in the USA.

Flexible Tank Construction

Flexible tanks are built using several different fabrics including those that are FDA and NSF 61 approved for drinking water. Fabrics are chosen based on the type of water you need to store, your surrounding area (temperatures and storage location), and the projected length of storage. Flexible water tanks can be made for potable water, non-potable/gray water, temporary septic, and also fuel storage.
