ABSTRACT
The development of effective wastewater treatment systems is required due to the complex characteristics of wastewater and the strict discharge and reuse criteria. Both centralized and decentralized treatment methods can be used to treat wastewater. The key characteristics of both centralized and decentralized treatment systems have been covered in this chapter. The wastewater must be collected, transported, and brought to the treatment facility appropriately to be treated effectively. As a result, wastewater management relies heavily on the transportation of wastewater from the point of generation to the point of treatment. Sewers, a system of interconnected pipelines, are responsible for conveying the wastewater. Sewage is transported from the point of generation to the treatment facility by a network of sewers, manholes, lifting stations, pumping stations, and other ancillaries. In this respect, the chapter discusses the types of sewerage systems and the characteristics of various sewer materials and shapes. The processes involved in the design of a sewerage network, which includes the estimation of sewage discharge, population forecasting, and hydraulic design of sewers, have been described in this chapter. Finally, the functions of the different sewer appurtenances have also been discussed.
