IRRIGATION

Flexible Water Bladder Tank for 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

Capacities that suit irrigation best

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

Prepare the ground before the tank arrives

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.

Level ground

Flat, firm ground with no sharp stones or debris.

Sand bed or ground sheet

Lay a sand bed or a ground sheet under the tank to protect the fabric.

No concrete base

No concrete base or permanent foundation is needed.

Connection

Connect the tank to drip lines and pumps

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.

Inlet and outlet fittings

Standard fittings include the inlet, outlet and flange for connecting pipes and hoses.

Valve and vent valve

A valve controls the flow, and a vent valve lets air in as the water level drops.

Drip lines and pumps

Connect the outlet to a pump or a drip-line manifold to feed the crop directly.
