Water Pollution

Contamination of water entering stormwater & waterways

Council investigates water pollution discharged into the region's waterways, creeks, dams and stormwater catchments under the Environmental Protection Act 1994 (the Act).   The Act prohibits water pollution and the potential for water pollution.  Pollution of waterways can occur in a number of ways, including:

  • release of a contaminant directly into a waterway
  • placing of a contaminant where it could be expected to move or be carried by rainfall into a drain, gutter, creek, river or other body of water.

Types of Water Contaminants

Water contaminants include things such as:

  • oil (including vegetable and cooking oils)
  • paint
  • lawn clippings, soil, sand, mud & other vegetation
  • concrete slurry
  • car, roof or driveway cleaning chemical runoff 
  • batteries
  • tyres etc.

A more comprehensive list of other substances prohibited from entering stormwater or other body of water is provided in the drop down below.  Please contact Council's Environmental Health team if you require further information or to report a water contamination incident. 


Reporting Significant Pollution Incidents

Reports of significant pollution incidents should be made to the Department of Environment and Science (DES) via the Pollution Hotline. DES are responsible for undertaking compliance activities on industries and activities that pose a greater environmental risk. Examples of significant pollution incidents include:

  • significant fish kills (not including bycatch)
  • chemical truck/vehicle rollover
  • factory fires (if a premises is currently on fire call 000 immediately)
  • pipeline break
  • major sewage spills

Building & Construction Sites

Water pollution as a result of poorly managed building and construction site waste can cause a serious impact on our environment.

Builders and developers have an obligation to prevent the deposit or release of sand, sediment, silt, rubbish or other building materials into Council gutters, stormwater drains and waterways.

Potential Penalties

Council’s Environmental Health Officers enforce the Environmental Protection Act 1994 to ensure that the potential discharge of sediment, sand, silt runoff and/or rubbish discharge into waterways is prevented to protect water quality. If you cause water contamination, Council’s officers can issue on-the-spot fines for failing to comply with the Act.

Significant fines and penalties exist and Council officers will investigate any valid complaints received.
