Over a period of a hundred an ten years, from 1901 to 2011, Indian urban population has exploded from 25.8 million to estimated 387 million. This has put extreme pressure on the fresh water resources of the nation due to concurrent expansion of agricultural sector, industrialization and urbanization. Thus, a self perpetuating problem has been generated, overload of sewage and lack of fresh water.
The purpose of this project is to visit the sewage treatment plant (STP) at Kalyani in West Bengal, India, and try to collect as much information as possible, on the various aspects of the treatment plant, such as demographic significance, sewerage conditions of surrounding areas, total area and individual areas of the various treatment and handling methods, plant capacity, energy requirements, treatment methods employed and number of such facilities, performance of the equipment and processes, quality (both chemical and physical), volume and location of the discharged water, presence of quality control mechanisms, methods of sludge disposal and so on.
After collecting the above information, these recorded parameters will be presented in tabular form and hence will enable one to compare this sewage treatment plant with other similar plants in West Bengal and rest of India. This will help us to assess the condition of such plant in the country and comment on the quality of the discharged water from these plants. The collected information will also be used to compare the previous and latest results and efficiency after the retro fitting is complete.
By 2050, it is projected that 50% of the Indian population is going to reside in urban establishments, while even now, public services are not able to keep up with the demand of the rapid urbanization. Majority of Indian cities lack sewerage infrastructure or sewage treatment plants. Thus, sewage and other domestic and commercial wastes are discarded into rivers or pond or in open dumps away from cities.

Objectives and Key Themes
The objective of this project is to provide an appraisal of the wastewater treatment plant (WWTP) located in Kalyani, Nadia, West Bengal. The study aims to analyze the plant's functionality and efficiency within the context of the town's needs and the broader landscape of wastewater treatment in India.
- Historical context of wastewater treatment in India
- Technical aspects of wastewater treatment plant design and operation
- Analysis of the Kalyani WWTP based on satellite imagery and field observations
- Assessment of the plant's capacity and efficiency in meeting the demands of Kalyani
- Comparison of the Kalyani WWTP with other treatment plants (implied)
Chapter Summaries
Introduction: This chapter likely introduces the problem of wastewater treatment in Kalyani, highlighting the growing population and increasing demand for effective wastewater management. It probably sets the stage for the subsequent investigation into the Kalyani WWTP, providing background information and context. The inclusion of graphs illustrating population growth and water demand emphasizes the urgency and relevance of the study.
Review of Literature: This section offers a comprehensive overview of existing literature on wastewater treatment. It likely delves into historical practices, tracing the evolution of wastewater management systems from ancient civilizations to modern techniques. The technical overview section probably examines various treatment processes, technologies, and their effectiveness. This chapter lays the groundwork for evaluating the Kalyani WWTP by establishing a theoretical and practical framework for understanding wastewater treatment principles and best practices. The review potentially discusses different sewage systems (sanitary, storm, combined), treatment methods (septic tanks, various plant stages), and technologies (bar screens, grit removal systems).
Satellite Imagery: This chapter analyzes satellite images of Kalyani town and the WWTP itself. The imagery likely provides a visual representation of the geographical context of the plant, its size and layout, and potentially indicates the extent of the sewage network. Comparison between the town's infrastructure and the WWTP's capacity is likely made. The analysis of satellite imagery likely aids in understanding the spatial relationships and the plant's location within the larger urban context of Kalyani.
Field Visit: This chapter details the findings from a field visit to the Kalyani WWTP. This would include observations about the plant's physical condition, operational processes, and any challenges or issues identified during the visit. The on-site assessment is crucial for evaluating the actual performance and effectiveness of the plant, supplementing the information obtained through the literature review and satellite imagery analysis. Direct interaction with plant personnel is likely discussed.

Frequently Asked Questions: Analysis of Kalyani Wastewater Treatment Plant
What is the overall purpose of this document?
This document provides a comprehensive preview of a study analyzing the wastewater treatment plant (WWTP) in Kalyani, West Bengal, India. It includes the table of contents, objectives, key themes, chapter summaries, and keywords of the full report. The analysis uses a multi-faceted approach, incorporating literature review, satellite imagery, and a field visit.
What are the key objectives of the study?
The main objective is to assess the Kalyani WWTP's functionality and efficiency in meeting the town's needs. This involves analyzing the plant's design and operation within the broader context of wastewater treatment in India. Specific themes include the historical context of wastewater treatment in India, technical aspects of WWTP design, analysis based on satellite imagery and field observations, capacity assessment, and (implicitly) a comparison with other treatment plants.
What sources of information were used in the study?
The study utilizes a combination of methods: a review of relevant literature on wastewater treatment, analysis of satellite imagery of Kalyani town and the WWTP, and a field visit to the plant itself. The literature review likely covers historical practices and modern technologies, while the satellite imagery provides a visual representation of the plant's geographical context and layout. The field visit allows for on-site observation and assessment of the plant's operational aspects.
What topics are covered in the literature review?
The literature review likely covers the historical evolution of wastewater management systems, various treatment processes and technologies, different sewage systems (sanitary, storm, combined), and treatment methods (e.g., septic tanks, various plant stages and technologies like bar screens and grit removal systems). It aims to establish a theoretical and practical framework for evaluating the Kalyani WWTP.
How is satellite imagery used in the study?
Satellite imagery is used to provide a visual representation of Kalyani town and the WWTP.
