Keeping it cleanphoto of pelicans floating on Werri Lagaoon

The Kiama Municipality has a number of river and creek systems that are parts of large catchments such as the Macquarie Rivulet, Minnamurra River, Werri Lagoon, Crooked River and Shoalhaven River catchments, as well as numerous small streams draining directly to the ocean.

The main impacts on water quality are from pollutants, including litter carried by stormwater runoff, untreated sewage/effluent entering waterways from on-site sewerage management systems and overflows or bypasses at sewage treatment plants and agricultural runoff.

Most urban stormwater pollution is caused by everyday activities and it is important for all of us to do our bit, especially in urban areas, to prevent waste from our homes or businesses polluting the stormwater system.  What seems like a little bit of waste from a home or business is a very serious problem when multiplied by every house in the community.  Our stormwater pollution fact sheet details causes and effects of pollution in our drains.  The Environment Protection Authority also provides some helpful hints in their brochure - Stormwater pollution - the difference is you.

Regulation of water pollution

Our environmental health officers and Ranger Services officers investigate complaints we receive relating to water pollution, and the NSW Office of Environment and Heritage investigates complaints regarding water pollution from scheduled premises and activities. Clean up notices, prevention notices or penalty infringement notices for water pollution offences may be issued by these officers under the Protection of the Environment Operations Act 1997.

On-site sewage management facilities

The management of domestic waste water and sewage is important for the health of the community and for the natural environment. All on-site sewage management facilities have been risk-classified based on their proximity to waterways, soil types and flood risk.  Read more...


Stormwater runoff can carry many pollutants from diffuse sources including nutrients, sediments and gross pollutants.  Stormwater management in the Kiama Municipality is important to not only protect the ecosystems where the stormwater discharges, but to also stop stormwater systems from becoming clogged and overflowing.  Read more...

Coastal and estuary management

The Municipality has two estuaries - Minnamurra River estuary in the north and Crooked River estuary in the south.  Management Plans are developed regularly to ensure the health of these important waterways are maintained.  Read more...

Beach health

Keeping our beaches healthy is very important to us.  We participate in the Beachwatch Program which is coordinated by the Office of Environment & Heritage and Sydney Water Corporation.  The program monitors water quality at various beaches throughout the Municipality and NSW. Read more...
