Overview

An efficient water supply and distribution system, a reliable supply of potable water, an appropriate system of wastewater collection, treatment and disposal, and an effective municipal solid waste management are essential for the health and well being of modern urban communities. The design, installation, operation and maintenance of these facilities are traditionally the responsibilities of local government engineers or consulting engineers employed by local government. This course therefore includes the modules on water supply and distribution system, conventional and advanced water treatment processes, wastewater treatment, sludge and solid waste treatment. In order to understand the principles and processes of water and wastewater treatment, there is a need to appreciate the vectors of waterborne diseases, microbiology, as well as topics in water chemistry. Environmental matters (notably solid refuse management) and legislation likely to be included in the responsibilities of a local government engineer are also included in this course.

Course learning outcomes

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. understand the global and local distribution of water resources, describe available sources of supply, apprise the water demand, explain the factors leading to water scarcity and measures taken to combat the water shortage;
  2. describe the essential components of a water supply and distribution system and design the capacities of trunk mains and service reservoirs in a reticulation network;
  3. understand the relevant principles of fundamental water chemistry and microbiology, describe the physical, chemical and biological characteristics of water which are of significance to urban water quality management and understand the guidelines for drinking water quality;
  4. understand the overview of conventional water treatment processes and modern trends in advanced water treatment;
  5. design the various components involved in a typical water treatment processes;
  6. describe the objectives of wastewater collection and treatment, understand the sources of wastewater and contaminants, design a wastewater collection system (sewer network) for a subdivision;
  7. understand the characteristics of wastewater and the measurements of them;
  8. describe the processes involved in primary, secondary and tertiary treatment of wastewater and design attached and suspended wastewater treatment processes;
  9. describe sludge treatment and disposal methods;
  10. describe the collection, storage, management and disposal of solid refuse;
  11. apply the state guidelines for water supply and sewerage schemes and recognise the relevant legislations.
