Design of Severage System and Sewage Treatment Plant for a Medium Size Cantonment

Abstract

Safe water and hygienic sanitation facilities are the two basic essential amenities the community needs for healthy living. Hence these two facilities are gaining importance in the country specially for medium size towns, satellite communities and rural human settlements. Though urban areas are being provided with sewerage systems and sewage treatment plant for safe disposal municipal sewage, rural areas and satellite communities still lack this basic need. This thesis is an effort to design an appropriate sewerage scheme for a medium size cantonment, keeping in view the typical requirements and problems related with scattered areas, thin population density and lack of skilled manpower and resources. In this thesis an attempt also has been made to provide an alternative to conventional sewer and sewage treatment plant in the form of small bore system and constructed wetland system respectively. Since scarcity of water for human use becoming a global problem specially in developing countries like India, where resources are limited and being exploited inefficiently apart from spurge in population, reuse of treated wastewater becomes a preferred disposal method rather than discharging it to the inland water bodies. Keeping this in view this work takes into consideration reuse of treated effluent for irrigation of golf course and open green areas where water requirement is more and problem of distribution of treated wastewater is less (being concentrated areas). Deeply involved in the problems of sewage collection, treatment and disposal of a cantonment area, where frequent clogging and unsatisfactory sewage treatment provides a big challenge to any engineer, this work of thesis has been selected as an effort to suggest a scheme and design which can overcome these problems and provide a reasonably better solution to these challenges.
