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

Added to this, approximately 60% of the household water that leaves the home as waste water is reusable as grey water and perfect to water gardens, wash cars and driveways and flush toilets.

We generate grey water every day in our homes, from our showers, baths, hand basins and washing machines. This grey water can be harvested using a JoJo tanks grey water harvesting system and reused for non-potable water purposes.

The result is that you will save money in the longer term as you would no longer need to use expensive municipal drinking water to water the garden or wash the car.

With the looming rise in the price of water, that’s good news for all South Africans. You will also reduce your carbon footprint and green your home.

A basic grey water harvesting system

The simplest grey water system consists of gravity feeding water to an underground sump (a 50F JoJo drum placed in an enclosure with an inspection cover) where it passes through a macro filter to remove hair fluff and lint.

The water is then immediately pumped or drip-irrigated into the garden.

With this system, the grey water must be utilised within 24 hours. If stored for longer, it changes into black water, develops an offensive odour and becomes foul.

These simple systems are cheap, cost-effective and relatively maintenance-free.

Advanced grey water harvesting system

A more sophisticated system can be designed and installed, which allows the grey water to be stored. This system requires the grey water to be treated and treatment is normally a combination of anaerobic, aerobic and disinfection stages.

A specialist installer is required for this option.

JoJo Tanks has a nationwide list of preferred installers (listed on the company’s website) so ask them if they install grey water systems.

You’ll quickly be on your way to use this water resource in your garden.

What is grey water and black water?

Grey water is defined as water from showers, baths and hand basins in the bathrooms and washing machine water.

Black water is generated from toilets, kitchen/ scullery sinks or the dishwasher. It is more difficult and complex to recycle or reuse.
