SYNOPSIS:

A  reliable supply of potable water, an efficient system of wastewater
disposal,  and  an  effective drainage system, are essential  for  the
health  and  well being of modern urban communities and of mining  and
isolated  industrial  activities. The design, installation,  operation
and   maintenance   of   these  facilities   are   traditionally   the
responsibility  of local government engineers or consulting  engineers
employed by local government.

To  understand  the principles and processes of water  and  wastewater
treatment,  there  is a need to appreciate the vectors  of  waterborne
diseases, sanitary 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 unit.

OBJECTIVES:

Upon successful completion of this unit the student should be
able to:

1. identify the issues which are of significance to public health
   engineering;
   
2. list and describe the organisms of importance in sanitary
   microbiology and the vectors of disease;
   
3. explain the significance of oxygen in wastewater treatment and
   of the determination of oxygen demand and concentration of
   oxygen in water;
   
4. describe the characteristics of water and wastewater, and
   explain the principles involved in the relevant water
   chemistry;
   
5. calculate the water demand of a community;
   
6. describe the sources of supply, treatment processes and
   distribution of water;
   
7. describe the components and processes involved in primary,
   secondary and tertiary treatment of wastewater;
   
8. compare and contrast attached growth and suspended growth
   treatment processes;
   
9. design a drainage system for a small urban area;
   
10. analyse problems in water and wastewater treatment and design
    the major components of treatment systems;
    
11. describe the collection, storage, management and disposal of
    solid refuse;
    
12. understand the state guidelines for water supply and sewerage
    schemes and have an appreciation of the relevant legislations.

OTHER REQUIREMENTS:

1    Students must achieve at least 45% of the maximum possible  marks
     in  each assessment, and at least 50% of the total marks for  all
     assessments to complete the unit successfully.
2    If  students submit assignments after the due date without  prior
     approval  then  a  penalty of up to 20% of the  assignment  total
     marks will apply for each working day late.
3    The   Faculty  of  Engineering  and  Surveying  will  NOT  accept
     submission  of  hand written or typed assignments  by  facsimile,
