Drinking water quality

Council supplies drinking water quality water to the residents of Dubbo, Brocklehurst, Wongarbon and Ballimore. Drinking water is also sometimes called “potable” water. Non-potable water refers to water that cannot be directly consumed safely.

Council has adopted a Drinking Water Quality Policy to ensure that customers can drink Council's tap water with confidence.

Water Quality

The generally accepted drinking water quality guidelines for drinking water quality in Australia and New Zealand today are developed and updated by the National Health and Medical Research Council (NHMRC).  The Australian Drinking Water Guidelines 2011, (ADWG-2011) also reflect these international guidelines, such as those developed by the World Health Organisation (WHO) and the results of current medical research.

Boil Water Notices

Sometimes a breakdown in part of the water treatment process means the treatment of water is not completed and it is not safe for customers to consume it. In such cases, water utilities, such as Council, issue Boil Water Notices.

These notices are issued by Council and the NSW Department of Health when the water treatment process has been compromised, or may have been compromised.

Council will deliver Notices to all affected properties. Residents should also consult Council’s website and the media.

When the Boil Water Notice is in force, tap water should first be boiled for at least a minute and allowed to cool, before it is consumed.

Boiled water should also used in activities that may result in ingestion of water, such as cleaning of teeth or gargling, washing uncooked foods such as salads or seafood, and making ice. Children should take boiled water in a bottle to schools in affected areas. Dishes should be washed in hot soapy water or in a dishwasher.

Residents should be careful when boiling water and be aware of the dangers of scalding.

When the Boil Water Notice is in force, tap water may still be used for purposes where the water will not be ingested, such as flushing toilets, watering lawns and washing cars.

Council will deliver Notices when the Boil Water Notice is withdrawn.

 
Water Sampling

Dubbo City Council operates its water supply system ensuring the water quality meets the Australian Drinking Water Guidelines 2011 (ADWG) and NSW Health standards.

Our water quality monitoring program consists of sampling and testing of critical points within our treatment process and delivery system. 

  • Treatment Plant - Samples are taken to monitor the source water quality which can vary due to catchment conditions.
  • Water Supply System - Samples are taken from locations, usually a residential house, and provides a typical profile of the quality of water being delivered to customers.
