Basics of sewer and waste water systems are described and explained in the lessons. In the first part, lessons focus on history of sewer systems and development of its purpose in time. Further, different types, layouts, means of waste water transport and disposition of sewers are described. Waste waters and storm waters are characterized. Hydraulic design of sewer systems is explained and practised. Further, sewer system structures, construction and rehabilitation methods of sewer system and OHS are discussed. In the second part, waste water composition is described together with waste water treatment process. Different layouts of waste water treatment plants are explained; consequent stages of treatment process are described in a detail, including sludge management. Design methods and calculations are explained and practised.
