Transport and storage:
The pillow tank is folded, packed in a sturdy polyethylene bag and placed in a strong wooden box together with all the tools and taps.

Instruction for use:
Suitable for use in static settings
When fully assembled, the tank serves as a potable water reservoir, especially useful in emergency situations.

Precondition for utilisation:
Fitting requires minimal training or orientation
Needs suitable flat level platform for installation

Emergency scenarios:
Use in all kinds of emergencies

Context in which item is mainly used:
Useful multipurpose unit for storage and transport of water supplies before and after treatment where existing storage facilities and water reticulation systems have either been rendered inoperable or are non-existent.
Common use includes localised camp or neighbourhood water distribution support.

Target population:
Approximately 1000 people per tank, depending on the refilling frequency.

Emergency scenarios where the item should not be used:
Not suited for use in batch flocculation of raw water.

Other Emergency scenario considerations:
Ground installation is susceptible to damage and filling can be awkward.
Restricted access and protective fencing highly recommended.

Climate considerations: May require protective measures in extreme climates from sun and cold.
