Objectives The student is expected to understand procedures in water resources development, water treatment processes and water reticulation, wastewater processes and water quality standards. On completion of the subject, the student is expected to competently carry out a simple water supply investigation, compute preliminary sizes of water treatment facilities and carry out basic calculations and conceptual layout of a wastewater and sewerage treatment and disposal system.
