Greywater diversion

Greywater used for sub-surface irrigation is diverted from the laundry and (if the site is large enough), shower and bath. Kitchen waste water is not used as it will naturally contain food particles and fats which will ultimately prove detrimental to soils and plants. Greywater is simply diverting (useable)  domestic greywater to the garden via a surge (buffer) tank and sub-surface drippers or the IWT system. The picture at right shows a retrofit of the diversion valve assembly adjacent to the washing machine.

Effective??   Sub-surface irrigation is extremely effective as it directs water to the plant root zone. As water is emitted below the soil surface, runoff and  evaporation are avoided. Sub-surface irrigation uses 15% to 25% of the volume used with surface watering and achieves far superior results as the sub-surface remains moist..

Independent of greywater usage: The system doesn't necessarily divert household wastewater to the garden whenever the washing machine is used or someone has a shower. The system can be programmed to operate independently to irrigate garden zones zones as and when required.

Elevated gardens? GreytoGreen can effectively irrigate gardens up to fifteen metres higher than the greywater source using a system specifically designed for the the purpose.

Washing powders? It is essential to use products with low (or zero) sodium and phosphorous content. Every major supermarket carries environmentally friendly products.

Your GreytoGreen dealer will cover laundry acceptable products from data supplied by Lanfax Laboratories. Just because the words "Eco Friendly" appear on product labels doesn't mean they are.
