Put simply, potable water is drinking water. Potable water has to be safe enough to be consumed by humans with a minimal risk of short-term or long-term harm. Typical uses of potable water are drinking, cooking, washing, toilet flushing and farm irrigation.

Water Quality Standards

Most naturally-occurring water requires quality management to make it potable and safe for public consumption. In Australia, the Australian Drinking Water Guidelines provide a framework for the management of drinking water supplies appropriate for local conditions. All drinking water service providers in WA must comply with these Guidelines.

Typical Contaminants

Contaminants of water that make it non-potable fall into two categories:

  • physical or chemical contaminants such as heavy metals, organic compounds and suspended solids such as plant matter or animal waste. These can be naturally-occurring or pollutants.
  • microbiological contaminants such as bacteria (the most common being E.coli), viruses and parasites.

Testing and Treatment

All potable water for public consumption must be monitored and tested prior to consumption to ensure the above contaminants remain within accepted parameters. This usually requires some form of treatment before it can be supplied. The most common treatments are:

  • chlorination, to deal with microbiological and some physical contaminants
  • filtering, to deal with physical and chemical contaminants

Licensed Water Suppliers

In Australia the Economic Regulation Authority issues licenses to supply potable water (and other water). Licensed entities can be State Water Authorities, Local Councils or private businesses.

Remote Area Supply and Cartage

An issue in West Australia is the supply of potable water to consumers ‘off the mains’ – whether a farm or business not connected to the main water supply, or a remote mine-site or community. Often these consumers source their own water eg. from rainwater tanks, dams or bores, in which case they must still follow the standard guidelines and regulations.

In other cases, potable water is transported by truck and tanker.

The WA Health Department publishes Guidelines on the Bulk Cartage of Drinking Water that covers water sourcing, water quality monitoring and treatment, hygienic operation and maintenance of cartage equipment, and the responsibilities of both the commercial supplier and the consumer.
