| Summary | This course extends the hydrology of the 2nd year Water Resources course (CIVE08011) and covers the practical considerations to be made resulting from the demand for water from community development by considering water consumption, water sources, water quality, treatment of water, wastewater and sludge, effluent disposal and river pollution. It provides Civil Engineers with the necessary tools to design a Water or Wastewater Treatment Plant, essential knowledge for the 4th Year Design Project on Potable Water. |
