The G-Flow is the only system on the South African market that is supplied with a specially designed grey water drip irrigation system and the option of a 6 station rotor irrigation controller. The system automatically waters different areas of your garden every time you bath/shower or do the laundry. 

International standards in many countries recommended using a drip tube/line irrigation system with a grey water system in order to prevent any bacteria in the grey water system from getting airborne or settling on top of the lawn & garden.

The GF drip tube/line irrigation pipe is specially designed for use with the G-Flow system. It can be used for both sub-surface and sub-mulch applications. This drip line is easily installed into gardens without interfering with the existing landscape.
