How Much Wastewater Does One Person Produce?

The wastewater produced per person varies. According to a recent study*, the average person produces 150 litres of wastewater per day. This average is estimated to be 370 litres/person/day. 93% of the total water is consumed indoors & only 7% outdoors.

Handling and treating wastewater is going to be one of the biggest challenges in the upcoming years. Wastewater management requires proper infrastructure, techniques and methods to manage the entire process.

Sources of Wastewater


Toilets are one of the major sources of wastewater. According to recent research, an average person flushes the toilet over 1500 times a year.

Bath and shower

It is essential to take care of your hygiene. According to a recent study, Showering drives almost 17 per cent of water use in homes, and an average family uses some 40 gallons of water per day in the shower*.


Washing machines utilise from 6 to 14 litres of water per kilo of dry weight clothes in a cycle. At the same time, older washing machines can use up to 150.


Dishwashers are pretty much common in large homes. A full dishwasher is more water effective than hand washing. Furthermore, most dishwashers are really filled to topmost capacity. The average dishwashers utilises 13 litres per cycle.

How to Reduce Wastewater Issue

First of all, try to use water only when necessary. Secondly, make sure that the wastewater is being treated. Wastewater treatment, when done right is environment friendly and helps in taking water back from the environment.

Wastewater Origin

The wastewater generally comes from industrial buildings as well as from commercial and residential areas.

Wastewater Treatment

Why wastewater treatment is important

Wastewater in a small quantity may not be harmful to the environment, but when it comes to huge industrial wastewater, it could cause serious issues to the environment if it’s not treated.

The wastewater contains contaminants that have a negative effect on the environment. If this wastewater gets to the rivers, it could affect sea life. Treating wastewater is essential for human health, animals and the environment as a whole.

The major purpose of wastewater treatment is to exclude as much of the suspended solids as possible before the remaining water called effluent is brought back to the environment.

The primary treatment excludes 60% of suspended solids from wastewater while the secondary system removes more than 90% of suspended solids.

What are the benefits of the waste treatment process?

Water treatment processing removes the contaminants from water. If the water is released into the environment without treating it could result in an environmental hazard.

There are different ways of wastewater treatment. This includes biological water treatment, chemical treatment, and sludge treatment. Chemical oxidation is used to disinfect water. In Physical Water Treatment, solid waste is removed from the water, and the remaining water is treated.
