Grey Water Systems
What is Grey Water?
In the Western Cape water is already an issue and with the growing population and limited resources for collection of water there will come a time when water restrictions and penalties will be permanently in place.
Here are some simply and effective ways of water management for any average household:
Grey water is made up of bath, shower, bathroom sink and washing machine water, it is not advisable to use your kitchen water as this is damaging to plant life because of the fat content.
An average household (family of 4) will use between 300l-400l of reusable water on a daily basis. The residues, soaps etc in the water in diluted quantities can provide useful sulphates and nitrates which some experts say is more beneficial to the garden than clean tap water.
It is advisable to use biodegradable products in the washing machine. The average suburban garden accounts for about 35% of domestic water consumption. Most of the concerns about grey water are to do with the hygiene aspect and odours of the water, but both these aspects are eliminated if the water is re-used as soon as possible and bacteria has not been given the the to produce.
