GREY TO GREEN IRRIGATION SYSTEM

A diversion plumbing system isinstalled in the laundy to send grey water to the garden from the washing machine.
A surge tank is used as a buffer beween the washing machine and the garden, as the average wachine machine pumpcan emit water faster than drippers can handle it.

The grey water travels from the surge tank to the garden via above-surface low density poly pipe andsubsequently directed to sub-surface drippers.

Effective

Sub-surface irrigation is extremely effective as it directs water to the plant root zone. As the water is emitted below the soil surface, run off and evaporation are avoided. Sub-surface irrigation uses about 15% of the water volume used with surface watering and achieves far superior results as the sub-surface remains permanently moist.

Washing powders
Are there components of greywater that can affect my garden?

As a general rule it is best to avoid irrigating gardens when the following are in your greywater:

  • Washing detergents with high phosphorous levels (many brands now have low or nil phosphorous, so choose one of these)
  • Bleaches and other disinfectants
  • Fats (from soaps)
  • Washing detergents using salt. Many cheaper brands use salt as a filler. It does not add to the washing power of the powder. Use only concentrates; or, better still, liquid detergents.

For a comprehensive list of detergents and the levels of salt and phosphorus that each contains please visit www.lanfaxlabs.com.au.

It is essential to use product with low (or zero) sodium and phosphorous content. Every major supermarket carries products which are environmentally compliant.
