K-Line Irrigation Systems & Support

K-Line irrigation designed around the block and water supply

K-Line is a practical, proven option for pasture, smaller blocks and irregular areas when it's sized properly. WaterForce plans new systems, extends existing lines and supplies compatible replacement components, with sizing checked against the block's actual flow and pressure. If another irrigation format fits the block better, we'll say so before you buy anything.

Why WaterForce for K-Line

Hydraulics checked first

Pipe, pods and sprinklers sized against your real flow and pressure, so the far end of the line performs.

New systems, extensions and parts

From a complete setup to a replacement pod, sprinkler, nozzle or fitting, matched to what's installed and backed by national stock holdings.

Fits your routine

Set times and shifting planned around the labour you actually have.

Parts and support nationwide

How a K-Line system works

Water is pumped through K-Pipe to a series of pods positioned across the irrigated area, each pod protecting and stabilising a sprinkler while the line is towed between sets. A complete setup includes the water source and pump, mainline or hydrants, K-Pipe sized for flow and run length, pods and sprinklers selected for the application, fittings and end assemblies, and a shifting plan. The components have to be compatible: adding pods or extending pipe without checking the hydraulics drops pressure and changes sprinkler performance down the whole line.

Where K-Line earns its keep

K-Line suits irregular areas, smaller blocks, slopes and anywhere portable low-pressure irrigation is an operational advantage, with configurations available for agricultural and selected effluent uses. Suitability comes down to terrain, soil intake, water availability, wind, stock movement and how often the line can realistically be shifted, which is exactly what our assessment covers.

System sizing based on flow and pressure

A proper K-Line design works through the irrigated area and shape, slope and access, water source and available flow, pump performance and pressure at the connection, the intended application, the preferred set time and shifting routine, and any existing components worth reusing. From there WaterForce specifies compatible pipe, pods, sprinklers and pumping, and confirms pressure at the far end of the line, the number that decides whether the block gets watered evenly.

Frequently asked questions

What is K-Line irrigation?

A portable system using sprinklers housed in pods along flexible K-Pipe, towed between irrigation positions. Simple, robust and well suited to NZ pasture.

What area can a K-Line system irrigate?

It depends on pod and sprinkler selection, spacing, sets, flow, pressure and operating time. We plan it for the specific block rather than quoting a blanket figure.

What pressure does K-Line need?

Enough at the sprinkler, after line length, pipe size, elevation and losses. We check the available flow and pressure at the operating condition, not the pump label.

Can K-Line operate on sloping or irregular land?

Yes, that's one of its strengths. Slope affects pressure along the line, so it gets factored into the hydraulic check.

Can I extend my existing K-Line?

Often, once the hydraulics confirm the pump and pipe can carry the extra pods without starving the line. We check before you buy the extension.

Can I mix parts from different setups?

Carefully. Pipe size, pod type, sprinkler and nozzle need to stay compatible or performance changes unexpectedly. Bring the details and we'll match components properly.

How often does K-Line need shifting?

Depends on set time, application and your routine. We plan the sets around the labour available, including during calving.

Why is the end of my line underperforming?

Usually pressure: a worn nozzle, a leak, an extension that outgrew the pump, or a changed pump duty. We check the full water path before replacing parts.

Does WaterForce supply K-Line parts?

Yes. Photos, measurements and any model information are enough for the local team to identify compatible pipe, pods, sprinklers, nozzles and fittings.

What maintenance does K-Line need?

Regular checks of pipe, couplings, pods and sprinklers for wear, leaks and blockage, plus confirming pressure at the far end. These simple checks protect performance through the season.

Get K-Line sized right

For a new system or extension, bring the block details, water source and pump information. For parts, photos and measurements are enough for the local team to identify what you need.
