You can provide your garden with safe, usable grey water by following a few simple rules:
Grey Is The New Green
Clean the grey water unit filter regularly.
Remember to wash hands after working with the unit.
Keep grey water out of the neighbour's property, public walkways and storm water drains.
Discuss the steps that need to be followed with regard to chemical usage/drain cleaners with your family and housekeeper.
Remember -What goes down your bathroom drain will ultimately end up in your garden.
When necessary, divert all heavily chemically fouled water directly to the sewer.
