IRRIGATION
A flexible PVC water bladder tank is a collapsible, non-potable water store for irrigation — a pillow tank of 5,000–50,000 L that holds farm water where a rigid tank is too slow or too costly to install.
Recommended capacities
Three sizes suit most irrigation work: a small buffer for drip lines, a mid-size farm tank, and a larger buffer for long watering runs. All are the same non-potable PVC bladder, in different sizes.

Ground preparation
A bladder tank needs level ground, cleared of sharp stones and debris, with a sand bed or a ground sheet underneath. A concrete base is not needed, and the tank can be moved when the site changes.
Flat, firm ground with no sharp stones or debris.
Lay a sand bed or a ground sheet under the tank to protect the fabric.
No concrete base or permanent foundation is needed.

Connection
Water leaves the tank through the inlet and outlet fittings, with a valve to control the flow and a vent valve to let air in as the level drops. Connect the outlet to a pump or a drip-line manifold, and the tank feeds the irrigation directly.
Standard fittings include the inlet, outlet and flange for connecting pipes and hoses.
