Why going grey is going green!

The average family of 4 uses between 300 and 350Lt of water per day (127 750Lt pa) and almost 90% of that water simply leaves the home as waste water!

With approximately 60%  of household water re-usable as grey water - perfect to water gardens, wash cars and driveways and flush toilets - it can potentially save thousands of liters of drinking water a year. (Not to mention the positive impact on the water bill!)

The simplest greywater system consists of gravity feeding water to an underground sump  (a 50Lt JoJo drum placed in an enclosure with an inspection cover) where it passes through a macro filter to remove hair fluff and lint and is immediately pumped or drip-irrigated into the garden.  With this system the greywater must be utilised within 24 hours. If stored for longer, changes into blackwater, developing an offensive odour and becoming foul.

A more sophisticated system pumps the water from the 50Lt JoJo drum into an above ground 750Lt JoJo Slimline™ tank, passing through a Venturi valve, that injects ozone into the greywater, cleaning, disinfecting and oxidizing all impurities.  This system allows greywater storage for a much longer period of time. A pressure booster pump attached to the tank, can pump the water to an irrigation system.

A greywater harvesting system using JoJo tanks, reduces water consumption and saves money and the environment.

WHAT IS GREYWATER?
Greywater is defined as water from showers, baths, hand basins in the bathrooms and washing machine water. It does NOT include water from the toilets, kitchen/ scullery sinks or dishwasher. This water is classified as black water.
