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
