Engineering technologists and associates working in the areas of state and local government, and private industry, are often involved with the design and construction of roads, water and wastewater services. It is therefore necessary for these graduates to appreciate the requirements of modern road technology, traffic operation and management, water supply treatment and distribution, the collection of wastewater and its treatment and disposal.

Topics covered in this course are road pavement design and construction (including bituminous surfacing techniques), traffic surveys and management, road maintenance, basic water treatment and distribution, and the collection, treatment and disposal of wastewater.

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

1. describe the commonly used methods of urban and rural road construction;
2. design road pavements using simple design methods;
3. apply the methods commonly employed in soil stabilisation;
4. integrate knowledge of materials, equipment and processes required to manage and supervise the construction of road pavements and bituminous surfaces;
5. design bituminous surfacings for road pavements;
6. describe the features of commonly used traffic control devices, and design their installation;
7. plan and carry out traffic surveys;
8. plan and design simple traffic management schemes, parking facilities, and facilities for pedestrians and cyclists;
9. assess the requirements for road maintenance techniques;
10. understand the global and local distribution of water resources, describe available sources of supply and water demand, explain the factors leading to water scarcity and measures taken to combat the water shortage;
11. 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;
12. understand the overview of conventional water treatment processes and modern trends in advanced water treatment;
13. understand and design the various components involved in a typical water treatment processes;
14. describe the objectives of wastewater collection and treatment, understand the sources of wastewater and contaminants, design a sewer for a subdivision;
15. explain the principles and process sequence in water and wastewater treatment plants;
