What type of water does greywater harvesting typically focus on?

Greywater harvesting specifically targets the collection and reuse of wastewater generated from household activities, such as washing hands, showering, and doing laundry, as well as from kitchen sinks (with some exceptions). The focus is primarily on reclaimed water, which is not suitable for drinking but can be recycled for non-potable uses, such as irrigation, flushing toilets, or cooling systems.

This is significant in water conservation efforts, as it helps to reduce the demand for freshwater supplies while also minimizing the burden on sewage systems. Greywater systems are designed to treat this wastewater to a standard where it can safely be reused, thus promoting sustainability and reducing overall water consumption.

In contrast, drinking water refers to potable sources that are safe for human consumption, rainwater pertains to harvested water from precipitation, and groundwater is derived from underground aquifers. These options do not align with the specific focus of greywater harvesting, which is aimed at recovering and utilizing the wastewater produced from everyday household activities.
