The average suburban garden can be fully irrigated with grey water produced by three washes each week from a 5 kilo top load washing machine.
Providing simple rules are followed, the garden will flourish.
Why Use Grey Water?
Water tanks are an asset and certainly useful when it rains but, if it doesn’t…….
Not only does the use of grey water in landscaping conserve precious water, but grey water may actually be better for plants.
Used correctly, grey water can result in more vigorous vegetation..
Unlike a lot of ecological stopgap measures, reuse is a part of the fundamental solution to a major ecological problem.
Is The Use Of Grey Water Safe?
The risk of contracting a disease by using grey water in the garden is equal to the risk of contracting a disease by soaking in a bath, or getting hands wet by contact with water in a washing machine. This isn’t meant to infer care should not be taken.
The GreytoGreen user manual illustrates precautions to be observed when using greywater.
Installed For Convenience
The GreytoGreen system is only installed by professionals.
Irrespective of slope in the site to be irrigated, hydraulic controls ensure each section receives adequate water.
Where appropriate, the system includes a self-activating pump capable of irrigating to 5 metres above the greywater source. The pump is also used for irrigation of flat sites requiring extended distribution lines and lawns.
Hydraulic controls are used to ensure each section of the garden receives the correct volume of irrigation.
When a dealer visits a site, the factors taken into account are:
Not all sites are suitable for grey water diversion. Excessively sandy or clay soils, immediate adjacency to natural water courses, location of the greywater source relative to the garden are a few of the factors taken into account.
Your certified retailer can advise on site suitability.
The size of the garden to be irrigated determines the amount of grey water required. This in turn determines source/s and frequency.
Sub-surface irrigation only requires 15% to 25% of that used with surface watering.
