I’m looking for advice from anyone with experience using a greywater filter/pump device in a backyard irrigation system. We have a newly built house with several outlets plumbed to an Aqua2Use greywater system, which is currently unused (so all greywater goes straight to the sewer). We’re about to start landscaping and are wondering how best to make use of it.
We will have around 100 square metres of garden bed (roughly half at the front of the house and half at the back), most of which will be planted with natives, a few fruit trees, a vege garden and a small lawn. We also have two rainwater tanks which supply hot water, washing machine and toilets in the house, and an additional small tank which can be used for hand watering. We would rather use greywater than rainwater for irrigation (as the rainwater can be used inside the house), but understand that the native plants might not appreciate too much of it.
One approach would be to install a subsurface greywater irrigation system in the back yard (which includes the fruit trees and lawn) and run a separate system off the rainwater tanks for the front (mostly natives). Is there a good way to work out how much garden bed we can support from the outlets we have plumbed to it?
We would happily seek advice from a greywater specialist if we could find one (we’re in inner Melbourne). So far everybody I’ve spoken to either doesn’t know much about greywater or only wants to sell their own system, not deal with a pre-existing one.
Any thoughts, warnings or recommendations for helpful professionals appreciated! Thanks.
