What is the current status of WWTP or STP Plants in India?
Environmental sustainability, including wastewater treatment and sewage management is an integral part of public health in India. It has considerable problems in providing efficient wastewater treatment with rapid urbanisation and industrialisation. This section will examine the present situation of waste water treatment and STPs in India along with its problems and efforts being made for it.
The Growing Challenge
Urbanisation and Population Growth: Increased sewage generation results from India’s increasing urban population, including its major cities of Mumbai and Delhi. According to the census of 2011 over 377. million of population were urban dwellers and this figure should have increased substantially after that year. Existing sewage infrastructure is being stretched by rapid urbanisation.
Inadequate Infrastructure: There is no proper sewerage in many of the cities and towns in India. Large amounts of sewage remain untreated and are dumped straight into water bodies such as rivers, lakes, and others, resulting in water pollution and health implications.
Industrial Effluents: Water pollution significantly comes from industries. Unlike municipalities that treat their wastewater, most industries discharge them untreated, thereby degrading the quality of water sources, leading to huddles in wastewater treatment.
Funding and Operational Challenges: Construction and operation of these treatment centers are affected by lack of enough finances and operational bottlenecks causing poor treatment processes.
Technological Gaps: Treatment carried out in most sewage treatment plant is suboptimal due to outmoded technologies, hence worsening water pollution problem.
Government Initiatives
Despite these challenges, the Indian government has undertaken several initiatives to improve the status of wastewater treatment:
Swachh Bharat Mission (Urban): This is an initiative started in 2014 and seeks to make all the Indian City’s free sanitation for the residents. It provides for the construction/renovation of public/community toilets and the development of STPs.
National Mission for Clean Ganga (NMCG): NMCG’s work primarily involves the cleansing of the Ganga river and its tributaries. On this mission are some of the projects for the construction and upgrade of STPs in the Ganga basin.
AMRUT Scheme: AMRUT-supported by Government of India, assists ULBs in improving basic infrastructure services like sewage & waste water treatment.
Namami Gange Programme: The Ganga Cleaning and Conservation Flagship Program. They include investment in STPs and measures to curb pollution from Ganga industries.
Challenges and the Way Forward
While these initiatives demonstrate the government's commitment to addressing the wastewater treatment challenge, significant hurdles remain:
Funding Shortfalls: Modernizing and expanding wastewater treatment infrastructure requires adequate funding. Exploration of public-private partnerships and innovative financing mechanisms is necessary here.
Capacity Building: It’s important to develop the specialist knowledge and managerial competency, required for effective plant work and maintenance in the area of wastewater treatment.
Technological Upgradation: Modern and efficient treatment technologies must be invested into improve treatment effectiveness and decrease expenditures on operations.
Awareness and Behaviour Change: Such activities as open defecation would be discouraged, while behaviour, including improper disposal of wastes, would cease because of public awareness campaigns and behaviour change programs to ensure that water bodies remain clean.
Monitoring and Enforcement: The environment needs strict enforcement of the regulatory policies by ensuring comprehensive monitoring of the pollutants produced by industries and local authorities on wastewater.
Conclusion
Wastewater treatment and sewage management in India have become complex problems today. The government has developed multi-faceted approaches to solving this problem that entail using various resources such as funds, technology, capacity development and the participation of people within communities. Indian government and individuals could achieve great strides in the cleaning of water bodies and ensuring a healthy ecosystem if there are combined efforts and continual investments.
