What is a Sewage Treatment Plant & How does it work ?
What is Wastewater ?

Wastewater, commonly known as sewage, is water used for various purposes. In residential settings, wastewater is typically generated in kitchens, laundry rooms, and bathrooms. In an educational environment, wastewater can arise from sources such as canteens and restrooms.

Unprocessed wastewater, if not treated, is unsuitable for recycling or safe release into aquatic ecosystems and the environment due to its high levels of impurities and disease-causing agents. Since wastewater primarily comprises water, sewage treatment facilities are indispensable for the purpose of rendering the water usable again for a multitude of applications.

What is a Sewage Treatment Plant ?

It might surprise you to know that we all drink and bathe in recycled water. The water we dispose of through our toilets is transformed into drinkable water, and sewage treatment facilities are tasked with the responsibility of purifying this water for human use or its safe return to natural waterways and seas.

Wastewater from sinks, baths, washing machines, toilets and other appliances has to go somewhere. After traversing miles of sewer network, it ends up in sewage treatment plants whose job is to treat and discharge it. Sewage treatment plants collect, treat, and discharge wastewater, providing a service essential to environmental and public health.

Without adequate treatment, sewage will leach into the environment and contaminate ecosystems. For example, sewage contains bacteria and chemicals that break down using oxygen in the water. In doing so, they use oxygen that fish and aquatic life needs to survive, so it needs treatment to preserve the ecosystem.

Returning sewage/wastewater to a specified quality for safe discharge is the most crucial role of the sewage treatment plant.

How does a sewage treatment plant work ?

Utilizing its internal processes, a sewage treatment plant functions by decomposing solid waste to generate a more environmentally sustainable effluent, thus promoting a cleaner and safer water discharge.

Wastewater and sewage are supplied to the primary tank, where the solid and liquid components separate. The resulting liquid is channelled into the biozone chamber. Within the chamber, a pump airs the waste and encourages friendly bacteria to condense the organic matter. This breaks down and purifies the result.

As it leaves the final waste chamber, the remaining waste is approximately 95% purified and suitable for discharge into nearby drainage channels or soakaway systems, pending approval from the appropriate environmental authority.

Why is Sewage Treatment Essential for Educational Institutions and Their Need for a Sewage Treatment System ?

Universal access to clean and safe water is a shared global aspiration, as uncontaminated and pure water, free from pollutants and impurities, is a fundamental necessity for ensuring public health and safety.

Now, let's ask ourselves a question! Are we willing to subject our students, who form an integral part of our society, our colleges, and our educational institutions, to utilize water that is tainted and contaminated? Are we willing to overlook the wastage of such polluted water? Absolutely not! The sewage treatment facility is here to help address this concern. Proper treatment of wastewater is essential to eliminate all contaminants.

So, let’s understand the importance of sewage treatment plants in Schools!

Students attending school should not have to compromise their health. Sewage treatment plants play a pivotal role in efficiently removing impurities, pathogens, and pollutants from wastewater while preventing water wastage. This not only ensures a safe environment for students but also aligns with the principles of environmental protection, embodying the three R's of sustainability: recycling, reusing, and renewing. In essence, sewage treatment plants perform a critical function in safeguarding both health and the environment.

Why are sewage treatment plants required for your school?

The necessity for an independent sewage treatment facility for the new educational institution primarily depends on the location. If the site doesn't have access to a major sewer system, the educational institution will need its own sewage treatment plant.

Rarely, even when connected to a primary sewage system, regulatory bodies may mandate that new educational institutions have their own system. In most instances, educational establishments situated in rural, remote, or countryside areas will require the installation of a sewage treatment system.

Conclusion :

Hazardous substances in sewage can present risks to both students and the environment. Hence, the presence ofsewage treatment facilities is always required in educational institutions, to minimize negative environmental effects.

Schools and colleges can explore tailored solutions by partnering with a water technology expert, such as Akruthi Enviro Solutions, which offers guidance, sewage treatment plant design, installation, testing, and maintenance to guarantee a continuous supply of safe and compliant water.
