OBJECTIVES:
 To educate the students on the principles and design of Sewage Collection, Conveyance, treatment and disposal.

UNIT I                                PLANNING FOR SEWERAGE SYSTEMS                                      (7) 
Sources of wastewater generation – Effects – Estimation of sanitary sewage flow – Estimation of storm runoff – Factors affecting Characteristics and composition of sewage and their significance – Effluent standards – Legislation requirements.

UNIT II                               SEWER DESIGN                                                                               (8) 
Sewerage – Hydraulics of flow in sewers – Objectives – Design period - Design of sanitary and storm sewers – Small bore systems - Computer applications – Laying, joining & testing of sewers – appurtenances – Pumps – selection of pumps and pipe Drainage -. Plumbing System for Buildings – One pipe and two pipe system.

UNIT III                            PRIMARY TREATMENT OF SEWAGE                                          (9)
