RAINWATER
Flexible Water Bladder Tank for Rainwater Harvesting
A flexible PVC water bladder tank is a collapsible, non-potable rainwater store — a 5,000–50,000 L pillow tank that captures and holds rainwater for irrigation and site use, without a rigid tank or concrete base.
Recommended capacities
Capacities that suit rainwater harvesting best
Two sizes suit most rainwater harvesting: a compact tank for a small roof catchment, and a mid-size tank for larger roofs and longer dry spells. Both are the same non-potable PVC bladder, in different sizes.

How it works
How rainwater harvesting works with a bladder
Rainwater runs from the roof or catchment through a downpipe into the bladder, where it is stored until it is needed. The tank sits on level ground close to the point of use, and water is drawn off through the outlet valve to feed irrigation or site use.
Roof catchment
Collect rainwater from a roof or other catchment and feed it to the tank.
Level ground
Sit the tank on level ground with a sand bed or ground sheet under it.
Draw-off valve
Take water from the outlet valve when it is needed.
Non-potable use only
Rainwater in a PVC bladder is non-potable
Rainwater stored in a PVC bladder is non-potable water. It is for irrigation and site use — not for drinking, and not food grade. Size the tank to the roof catchment and the dry period between rains.
Irrigation
Stored rainwater feeds drip lines and farm watering.
Site use
Water for construction site use and dust control.
Not drinking water
Rainwater in a PVC bladder is non-potable — it is not drinking water.
