Water treatment facilities are designed to speed up the natural process of purifying water. With billions of people and even more wastewater, the natural process is overloaded. Without wastewater treatment, the amount of wastewater would cause devastation, as it still does today in developing countries.
What is the purpose of wastewater treatment?
Wastewater treatment helps remove or reduce several harmful particles from the water before it can be released into the environment. There are three types of treatments available - Primary which involves the removal of suspended and floating solids from raw sewage, Secondary treatment which eliminates any dissolved organic matter, and Tertiary which removes almost all of the impurities from sewage water.
What happens if wastewater is not treated properly?
If wastewater is not treated properly, it can have dire consequences. While toxins seeping into the food chain can be one of the outcomes, for businesses, which require a 100% clean and pure energy source, it could result in the poor quality of output and contamination of processes.
Why is it important to conserve water?
It is hence important, if not imperative, for us to conserve water and protect this resource for future generations. Wastewater is any form of water that has been contaminated by a commercial process, which includes substances such as human waste, food scraps, oils, soaps, and chemicals or domestic processes which include water from sinks, showers, ...
Is freshwater a resource?
Clean freshwater is a limited resource. While the world is grappling with drought and calamities, freshwater is becoming one of the most precious resources - without which a thriving civilisation will be impossible. Although 71% of the earth is made up of water, a very small percentage of this is available for use.
Why treat water?
The reason for treating water in the first place is to remove traces of bacteria, viruses, dirt, chemicals, and biological compounds from water and make it safe for drinking and carrying out other activities. It can be almost impossible to remove the traces of these contaminants from the water completely.
Why is water purification important?
Clean water is a necessity for every human and with the help of water purification systems you can ensure that the water that you use is safe, clean, and free from disease-carrying organisms.
How to purify water?
If you live in an area where these diseases are a risk, you can purify your water using the reverse osmosis method. Here, a membrane is used to separate water at different concentrations. These pores on the membrane are small enough to prevent viruses and bacteria from passing through. Reverse osmosis water purification is also helpful when it comes to removing chemical contaminants like lead, chloride, and sodium from the water.
Why is desalination important?
Since saline water is of no important use and is available in abundance on earth, desalination can help solve the issue of water scarcity in the world. Lastly, another major importance of water treatment is that it helps fulfill the ever-increasing demand for clean and potable water. Treated water is used for drinking, agriculture, irrigation, ...
What is the smell of tap water?
The foul odor that is given off by tap water sometimes comes from hydrogen sulfide. Most water treatment systems are designed to not only rid your water of contaminants, but also help to improve the appearance, taste, and smell of your water and therefore, make it satisfying.
Why does tap water taste bad?
However, there is the problem of tap water having a distinct taste and this is because of the use of chlorine as a disinfectant. The foul odor that is given off by tap water sometimes comes from hydrogen sulfide.
What is hard water?
Hard Water contains an excessive amount of calcium and magnesium. Water can be softened by using a water softener or descaler.
Why is wastewater treatment important?
Wastewater treatment is fundamental to protect the health of many different ecosystems. Wastewater, properly treated, is a source of water for many purposes. Good wastewater treatment allows the maximum amount of water to be reused instead of going to waste.
Why is water important to the environment?
However, wastewater contains many harmful substances and cannot be released back into the environment until it is treated . Thus, the importance of wastewater treatment is twofold: to restore the water supply and to protect the planet from toxins.
How long does a septic drain last?
The average septic drain field lasts about 20 years, but if properly cared for can last 50 years. Learn four tips to extend the life of your drain field.
What are the health effects of wastewater?
Untreated, the chemical compounds and pathogens in wastewater can harm the health of animals, plants and birds that live in or near the water. It can also contaminate crops and drinking water, affecting human health.
Can water be reused?
All communities, especially areas with water scarcity, need to ensure they have good water treatment processes in place so that treated water can either be reused or returned to the water cycle, but never wasted. Wastewater can include contaminants from both residential and commercial use.

Regularly pumping your septic tank keeps the system in good shape. Learn about a few signs that your septic system needs to be pumped.
Why Treat Wastewater?
It's a matter of caring for our environment and for our own health. There are a lot of good reasons why keeping our water clean is an important priority:
Wastewater treatment
The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
Wastewater is toxic
Although some fish and other animals can break down toxins, toxic water is a serious risk to human health and is responsible for millions of deaths each year, mostly in developing nations.
What is wastewater treatment? How does it work?
Wastewater treatment is the process of filtering contaminants out of water that has been previously used for another purpose. This process can occur both naturally and through manmade efforts.
Water treatment plants are complex systems
What exactly happens at a wastewater treatment plant? While there are different methods, some of the systems use similar components. For example, the Four Rivers Sanitation Authority in Illinois treats wastewater by first pumping it to a higher elevation for gravity to pull the water through the first part of the treatment and filtering process.
What is in wastewater, exactly?
Since wastewater comes from human use, thousands of contaminants are present, although not all are present in every batch of water. In general, there are both inorganic and organic compounds found in wastewater.
Wastewater treatment can help with water scarcity
There are many places across the world that experience droughts and water shortages on a regular basis. Without treating wastewater, drinking water sources become (and remain) contaminated. This includes rivers, lakes, and streams.

There is no higher priority for EPA than protecting the health and safety of Americans. EPA is providing this important information about COVID-19 as it relates to drinking water and wastewater to provide clarity to the public. The COVID-19 virus has not been detected in drinking-water supplies. Based on current evidence, the risk to water supplies is low. Americans can continue to use and drink water from their tap as usual. EPA also encourages the public to help keep household plumbing and our nation’s water infrastructure operating properly by only flushing toilet paper. Disinfecting wipes and other items should be disposed of in the trash, not the toilet.
