Waste is one of the biggest challenges faced by the world today, and the future of solid waste management depends on every single individual. Although government authorities, leaders of the nations, municipalities and local communities are working hard to manage the extensive amount of waste generated every day, a radical change in mindset at an individual level is the need of the hour.

On a broader note, improper waste disposal and management, which includes public littering, lack of waste segregation, uncontrolled collection and disposal and poor waste treatment practices, have greatly impacted the world. According to a World Bank report, 2.01 billion tons of municipal solid waste is generated every year across the world, out of which it is estimated that 33% is not managed properly, impacting the environment.

Muttukadu, a small town located on the outskirts of Chennai, is well-known for the lush greenery surrounding the place, the backwaters and the serene environment. However, the region has lost its sheen and the diverse flora and fauna in recent times due to growing algal blooms in Muttukadu Estuary.

Algal blooms are not a new phenomenon as you might have seen the green algae covering large areas of coastlines, lakes, ponds, reservoirs etc. However, the exponential growth of harmful algal blooms in freshwater is a matter of grave concern for aquatic organisms, the environment, as well as public health. Therefore, urgent solutions are required to prevent algal bloom.

An onsite septic tank system, installed beneath the ground, helps to manage the household waste generated on a daily basis. In India, the septic tank system is beneficial in rural and urban areas where a connection to sewage treatment plants does not exist. However, it is important to know that these systems are expensive. Thus, regular maintenance is essential to prevent system failure. Septic tank sludge removal or reduction is the best way to keep up the optimal performance and prolong the life of septic systems.

For a country like India which is looking to revolutionise its sewage wastewater management systems the gaps in the functionality of current treatment systems are very high. The CPCB’s 2015 census report states that out of India’s 816 STP’s , only about 522 are fully operational and do not meet their entire capacity of treating sewage.

Septic tank systems play an important role in managing the household waste generated every day. It is one of the most common forms of treatment systems due to easy installation, low costs and performance. Also, it is widely used in urban and rural areas because sewerage systems are not practical and very expensive. However, the performance of a septic system can be affected due to the extensive use of septic tank cleaners and other chemicals. And experts suggest that septic tank failure often leads to reduced effluent quality, posing a significant threat to water quality.

Untreated sewage is one of the major 21st-century challenges faced by the world today. Several factors such as population growth, rapid urbanization, industrialization and lack of innovative sewage water treatment solutions have led to an increase in sewage volume globally.

An extensive amount of sewage water is generated every day from households, industries and agriculture. Raw sewage contains harmful components such as chemicals, dangerous pathogens, toxin substances, debris and heavy metals. Therefore, when the sewage is released into the environment without proper sewage water treatment, it causes water pollution. Consequently, it threatens to impact human health and the environment

Globally, billions of people do not have access to basic sanitation facilities even today, and it is affecting the health, economy, environment and communities in different ways. In developing countries of the world, the poor sanitation situation leads to public health hazards like diarrhoea, cholera and dysentery resulting in deaths, especially of children, every year. It costs billions and affects economic growth. The open defecation practices pollute the environment and aesthetic beauty of the place.

Water contamination is one of the major challenges worldwide. Several factors such as rapid urbanization, industrialization, population explosion and changing lifestyle habits have contributed to the pollution of water bodies and health problems to humans. In this context, wastewater treatment is of great importance to prevent water contamination and protect the environment.

Aquaculture is one of the fastest-growing industries in the world today. For a large population living in different parts of the world, fish is the main source of nutrient, and thus it is integral to the dietary culture. However, different kinds of disease outbreaks and poor water quality have been plaguing aquaculture and affecting its production rate. Although conventional solutions like antibiotics are used, there is a growing concern about their extensive use and related adverse effects on the aquatic ecosystem and aquatic living beings.
