Answers
A clean and healthy city needs a proper sewage system”. Explain.
- Sewage disposal is a major form of coastal pollution throughout the world.
- Sewage outfalls near coastal communities release human waste as well as other organic matter, heavy metals, pesticides, detergents, and petroleum products.
- Wastewater can contaminate the local environment and drinking water supply, thereby increasing the risk of disease transmission.
- Community wastewater management and adequate sewer systems play important roles in sanitation and disease prevention.
- Wastewater is treated in 3 phases: primary (solid removal), secondary (bacterial decomposition), and tertiary (extra filtration).
- For example, there are concerns about pharmaceuticals, microbeads, caffeine and many toxic contaminants that are not removed during the treatment process.

Answer:
Adequate sanitation, together with good hygiene and safe water, are fundamental to good health and to social and economic development. That is why, in 2008, the Prime Minister of India quoted Mahatma Gandhi who said in 1923, “sanitation is more important than independence” [1]. Improvements in one or more of these three components of good health can substantially reduce the rates of morbidity and the severity of various diseases and improve the quality of life of huge numbers of people, particularly children, in developing countries [2],[3]. Although linked, and often mutually supporting, these three components have different public health characteristics. This paper focuses on sanitation. It seeks to present the latest evidence on the provision of adequate sanitation, to analyse why more progress has not been made, and to suggest strategies to improve the impact of sanitation, highlighting the role of the health sector. It also seeks to show that sanitation work to improve health, once considered the exclusive domain of engineers, now requires the involvement of social scientists, behaviour change experts, health professionals, and, vitally, individual people.
Throughout this paper, we define sanitation as the safe disposal of human excreta [4]. The phrase “safe disposal” implies not only that people must excrete hygienically but also that their excreta must be contained or treated to avoid adversely affecting their health or that of other people.
