It is important to protect the health– The harmful chemicals, metal and other contaminants present in water are dangerous for the health of humans and other organisms living on this planet. These harmful substances and toxins lead to various health problems like asthma, cholera, diarrhea, asthma, cancer, skin disorders and even death. Hence, this will reduce the annual death rate of people caused by drinking contaminated water.
It helps to ensure that water is not wasted – The wastewater treatment plants use water discharged from households and industries which is purified and discharged back to the community and natural environment. Thus it reduces the wastage of water.
It helps to restore the water – With this process, water is reintroduced back to the cycle of nature.
To protect the environment– Water treatment is very much helpful for the environment. It helps to balance the water cycle by maintaining groundwater and surface water.
The water purified at the treatment plants can be used for various purposes like drinking, households use, industrial application, agriculture, and irrigation purposes, etc. This will solve the problem of water shortage and countries with limited access to safe water will be benefited.
Water purification plants are also important as they fulfill the increasing demand for water.
Desalination is another way of water purification. It is important as it converts the saline water (which is actually of no use and is available in abundance on the earth) to potable water. This can help in solving the problem of water scarcity in the world.
