The Bulk Water System Optimisation (BWSO)

The Bulk Water System Optimisation (BWSO) course covers the whole water cycle spectrum from raw water source quality, fit-for-purpose water treatment processes, domestic and industrial wastewater treatment processes as well as desalination technology for water reuse and zero liquid discharge (ZLD) requirements.

Course topics covered are:

Day 1: Potable Water Treatment Processes

  • Types of source water – fresh, ground, desalinated or reused water
  • Typical water quality and contaminants of concern (CEC)
  • Origin and impact of Eutrophication
  • Fundamental water chemistry
  • Drinking water standards
  • Drinking water consumption demand benchmarks
  • Management of water losses and leak detection
  • Water treatment unit processes – coagulation, sedimentation, filtration, disinfection

Day 2: Biological Wastewater Treatment Processes

  • Wastewater characteristics – COD, ammonia, phosphorus, etc.
  • Biological wastewater treatment processes (WWTP) – biological nutrient removal (BNR)
  • WWTP energy efficiency improvement – reducing oxygen demand
  • Power generation to achieve Energy Net-Zero
  • Wastewater treatment unit processes
  • Alternative treatment processes and resource recovery from wastewater

The course aims at providing the attendees with the following:

  • A fundamental knowledge of the processes employed in potable water treatment plants.
  • Knowledge of water chemistry and the standards applicable to potable water in South Africa.
  • Opportunities for optimization in these processes, upgrading, improving, and expanding capacity of these plants.
  • Fundamental knowledge of water treatment processes employed.
  • Opportunities to improve the system efficiency and case studies of where technologies have been implemented.

CPD Accreditation

All NCPC-SA courses are accredited by ECSA and CPD letters will be issued to candidates that attend all sessions of a particular course. Attendance will be monitored via the video function of the on-line training platform.


Candidates will have an option to write a test at the end of the training. The test is not compulsory, however, NCPC-SA certificates of competence will only be issued to candidates who pass the test with a minimum score of 70%.
