4.Storage tank
Explanation:
About 40% of the wastewater generated in a household is greywater containing contaminants like soap, detergent, dead skin, hair and oil. Each member of a household generates about 90 litres of greywater daily. Once treated, this water can be used for gardening and toilet-flushing. It can meet up to 40% of household water needs. However, it is important to remember that this water is not suitable for drinking; the water should be further treated using methods like ozonation to make it potable.
There are different methods for greywater treatment. The one discussed here uses a reed bed, also known as planted gravel filter, a natural treatment system. It can be set up either on the rooftop, or in the plot around your house. The overall long-term savings from this system is quite high.
