IF want to reduce your water consumption then you’ve most likely been researching or already have installed a grey-water system.

Grey water allows plants to grow where fresh water may not be readily available.

Before you go ahead and re-route all your plumbing, here are few things to take note of:


• Use grey water piped from the kitchen sink or dishwasher. Both use chemicals that are toxic to plants and some even have long-term effects on certain plants.

• Allow grey water to sit in a container or silo for long. It needs to keep moving or it can stagnate and turn toxic from bacterial growth.

• Allow access to the grey water for pets and children – grey water is safe for plants, but not for consumption.

• Let grey water pool in the garden. Grey water should never flood the garden as the bacteria in the water will clog the soil and prevent drainage. Irrigate properly so it disperses and drains into the soil quickly.

• Let grey water into any irrigation system. Rather spray using a hose and pump to prevent contamination.


• Use biodegradable shampoos, conditioners, detergents and soaps. This will lessen the likelihood of bacteria and toxin buildup.

• Catch the “warm up” water from the shower. This is the highest quality grey water as it is soap free.

• Spray grey water with a low pressure hose or sprinkler.

• Use the grey water as soon as possible so it doesn’t sit and stagnate. - Supplied.
