PCDI Irrigation

LAS Systems

In New Zealand PCDI (Pressure Compensating Drip Irrigation) is one of the most common methods of applying treated wastewater to land.

It’s why at WaterFlow we don’t just focus solely on the treatment system like others do. We consider your vision for your property first and then find the LAS that will achieve this and finally the wastewater treatment system that will match and meet your needs.

Your LAS or ‘Disposal Field’ has the largest ‘footprint’ of all of the components and is the ‘subject’ of most Council regulations, involving ‘setback’ distances from features like buildings, waterways, flowpaths, stormwater drains, ponds/dams, bores, ground water/water tables, flood zones, boundaries etc… There is also requirements around steepness of slopes to consider which can have a bearing on which LAS you can get consented, on your site, such as irrigation type fields verses soakage type fields.

The Waterflow Team is well versed in all those constraints and options and very passionate about helping you design the ultimate LAS for your property.

PCDI Irrigation Pressure Compensating Drip Irrigation (PCDI) is a flexible irrigation system that requires higher levels of wastewater treatment.

It is commonly required on heavy clay soils where soakage is limited, and it is important that the treated water is spread evenly.

  • PCDI has small emitters allowing a limited flow, this forces the liquid to distribute across the entire field rather than pooling in one area.
  • Due to the fine emitters, the treatment plant must treat to secondary level and the lines regularly cleaned.
  • The PCDI lines can be of varying lengths and run across contour to a certain degree, giving much more flexibility to the layout and shape of the irrigation area.
  • At the end of the lines are flush taps, that allow the flushing out of any contaminants that might build up over time, it is best done with clean water. At the end of the main feed line is the end flush tap. It is similar to other flush taps, but some systems will have a hose fitting for back flushing properties.
  • If your irrigation is buried, the flush taps will be found under purple flush boxes. These have a purple lid and sit flat to the ground to allow the area to be mowed.
