Dripline Irrigation

A dripline is a plastic hose that slowly and efficiently releases water.

This technology combines irrigation and water conservation. The hoses are at ground level, but may be covered by mulch. Water is taken up by roots and little is lost to evaporation. This is the method of choice when the plants have high individual value. They may be orchard trees or rows of perennial plants. It may also appropriate when sprays are not wanted or because the water is scarce.

A dripline has clever technology in it and is not a 'garden hose with pin-holes'. It is designed to deliver water constantly, and resist clogging by particulate matter. When particle build-up becomes a problem, the hose should readily flush clean. Hose connection is not complex - just basic careful plumbing.

If short lengths suffice, especially on near flat land, then non-pressure compensation hose can be used. High performance hose is independent of substantial changes in pressure. This means not only can extended lengths be used, but the hose can run up and down contours in the ground.  Some examples are given below.

Techline PC hose (brown)Techline pressure compensating brown hose The brown colour makes this hose inconspicuous, and if mulch is used as a further aid to water conservation, the hose is invisible.


For residential and indoor use, a 13mm low density polyethylene hose is an option.

Dripline dripper
This is a dripper, a dripline water outlet. Just  one of a number of designs. They are fitted every 40 cm or so along inside the hose. Irrigation water moves on a turbulent zigzag path (bottom segment), which keeps any interfering particles in suspension so they pass through and on down the hose. Some water passes through the gel-like filter and this releases water into the soil and plant roots.

Total water delivery from a hose can be say 10 L per hour. This is nowhere near as abundant as a water spray, but very targeted to plant use rather than plant environment.
