Treatment and reuse of treated wastewater

The reuse of treated wastewater—often referred to as "water reuse"—involves collecting, treating, and repurposing wastewater from showers, sinks, bathtubs, and washing machines (known as "greywater"). This practice helps to reduce the consumption of drinking water.

What is greywater?

Greywater is wastewater from showers, washbasins, bathtubs and washing machines.

It contains no faecal matter or urine, unlike blackwater (toilets), which makes it easier to treat.

Greywater accounts on average for 60 to 80% of the water used in a home.

💡 What uses after treatment?

After suitable treatment, this water can be reused for non-potable purposes, such as:

watering green spaces and public gardens,
supplying toilet flushing (up to 30% drinking water savings in a home),
cleaning roads, car parks and building floors,
certain industrial or agricultural uses (under strict conditions).

👉 This is what is known as Treated Wastewater Reuse.

📜 Regulatory framework

Laws and regulations on greywater reuse can vary from place to place. It is therefore important to comply with local requirements for water quality and public health. Permits or authorisations may be required to set up a greywater reuse system.
