Managing our water supplies

Managing our water supplies

We use our Drinking Water Quality Management System (DWQMS) to manage South Australian’s drinking water supply systems and to deliver safe drinking water to our customers.

A key principle of this approach is having barriers and preventive measures in place to reduce hazards along the chain from the catchment to the customer’s tap. The focus is on preventing and minimising hazards at the earliest point in the water quality management process and not relying solely on downstream controls. Hazards in the water can take many forms and are generally categorised into three types – biological, physical or chemical. Typical hazards found in South Australia for each of these categories include:

  • Biological – algal metabolites’ by-products and pathogens (e.g. Cryptosporidium, Giardia, E. coli)
  • Physical – sediments (turbidity) and colour
  • Chemical – pesticides, hydrocarbons, iron and manganese.

We have identified potential water quality hazards and the associated level of risk for each of our water supply systems using our water quality risk management framework. Hazards identified during this process are incorporated into our corporate management platform SAAM (Safe, Actioned, Assured, Managed).  SAAM is used to capture, assess, prioritise, manage and report water quality hazards and actions. It is also used for planning our water quality improvements (including operational and capital improvements) and identifying changes or improvements in monitoring, procedures, training and quality verification. This risk assessment process is integrated with other business areas of SA Water.

The following table shows the barriers, water quality management objectives and preventative measures from catchment to tap.
