Which of the following describes the function of a greywater irrigation system?

A greywater irrigation system is designed specifically to use recycled water from household activities, such as washing dishes, laundry, or bathing, to irrigate plants in a sustainable manner. The correct answer focuses on the proper management of greywater by ensuring it is treated or stored adequately before being applied to the landscape.

This method contrasts with approaches that suggest simply dispersing greywater on the surface or directly applying untreated greywater, as these practices can lead to health risks due to potential pathogens present in the water. Proper storage is necessary to allow any suspended solids to settle and to potentially use biological processes to break down contaminants. Thus, the function of a greywater irrigation system is not only about the application of the greywater itself, but also about ensuring the water is suitable and safe for use on plants, thereby supporting sustainable landscaping practices while protecting public health and the environment.
