Family drip system. Drawing: RELMA.

The Family drip system, developed by Netafim Irrigation Equipment and Drip Systems company in Israel, is a low-pressure system intended for a family plot. Similar to the drip systems discussed above, no central pressurized water system or power source is required, and the technical level is such that it is easy to understand. The drip tube is made from heavy-duty polyethylene pipes (inside diameter 6 mm, outside diameter 8 mm) for low-pressure performance giving a drip emitter flow rate of 0.65 l/h at 1 m pressure. The drip outlets are spaced at 30 cm.

Suitable conditions

This system has been used in Israel and China. Plans are under way to make it available in many countries of the world through the Netafim distribution network of companies.

Construction, operations and maintenance

System components

• 920-litre plastic water tank
• 1-inch screen filter (120 mesh)

• 20 m x 40 mm PE pipe
• 14 dripline start connectors for PE pipe
• 14 insert connectors for dripline
• 14 dripline end closures
• 800 m x 8 mm dripline.

Assembly instructions

1. Order material from your supplier according to the area to be irrigated.
2. Construct a stand from locally available material.
