STC specializes in the manufacture of pillow tanks, onion tanks and various size bladders. They are collapsible, flexible storage tanks that provide temporary as well as long term liquid storage. These types of containers are useful for oil spill recovery operations, bulk liquid transport, storage of bilge slops, potable/gray water, chemicals or fuel storage.
