Irrigation & Grey Water

Water is the key to all life, and we at Welkin emphasize the importance of using professional, metered systems, that in the long run, saves money, and effort and ensures that all parts of the garden get sufficient water to guarantee maximum growth throughout the year.

Utilizing a professional irrigation system also benefits the environment, as water is a scarce resource.

An irrigation system allows for the effective distribution of water in a set time regardless of whether the homeowner is at home or not.

Welkin endorses different irrigation systems in South Africa.  

This being said, we recommend that our clients install a Grey Water System.

Grey Water 

In South Africa, 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. 


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 200-3001 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.
