How Much Wastewater Does A Person Produce?
Wastewater refers to the water we use when carrying out everyday tasks, which then drains away into the sewers. There are varying estimates about the average amount of wastewater a person produces, but it’s believed to be somewhere between 150 and 370 litres every day. The vast majority of this is water consumed indoors, with less than 10% outdoors.
As the population increases and the total wastewater production goes with it, the treatment of wastewater is set to become a significant challenge. To manage wastewater, there must be adequate infrastructure in place. Households may need to start thinking about reducing their excess water usage.
Where does wastewater come from?
A washing machine uses between 6 and 14 litres of water per kilogram of clothes in a single cycle. Older washing machines sometimes use as much as 150 litres for every kilogram.
Bathing and showering
Good hygiene is an important part of our lives. But showering may make up almost a fifth of all water use in the average home, with as much as 180 litres of wastewater being produced each day by the average family.
Flushing the toilet creates a lot of wastewater. Toilets bought before 1993 usually have a cistern that uses 9.5 litres per flush, while newer toilets tend to use 7.5 litres. With the average person flushing more than 1500 times a year, that’s around 11,250 litres of wastewater every 365 days.
It is very common to see a dishwasher in a large, modern home. Dishwashers are usually more water-efficient than hand washing, but they are rarely filled. They tend to use around 13 litres per cycle.
How to reduce your wastewater footprint
The first thing to do is to try and only consume the amount of water you need. After that, you need to be sure that your wastewater is being treated.
Most wastewater comes from industrial buildings, with commercial and residential areas coming behind. Large quantities of industrial wastewater are full of contaminants that can be extremely harmful to the environment if not treated. As it makes its way into rivers and oceans, sea life is drastically affected. As such, wastewater treatment is essential for the health of humans, animals, and the environment.
The main objective of wastewater treatment is the removal of as many suspended solids as possible. In the primary treatment, around 60% of solids are excluded from the wastewater, and the secondary system removes 90%+ of suspended solids.
The remaining water, or effluent, is returned to the environment.
Why is wastewater treatment important?
Wastewater treatment removes harmful contaminants from water. Releasing it into the environment without doing this first is hazardous to all life.
Wastewater treatment can be handled in different ways, including:
- Chemical treatment
- Biological water treatment
- Sludge treatment
These treatments are typically applied after physical water processing, whereby filters exclude solids from the water. The treatments that follow then make the water safe to return to the environment.
