The Camden Local Government Area is growing rapidly as rural lands are transformed into residential suburbs. Increased urban growth will result in increased hard surfaces such as dwelling roofs, footpaths, driveways and roads. Hard surfaces reduce the amount of rainwater available for absorbing into the ground and cause increased run off. This is called urban runoff which is directed to our local waterways through stormwater drains. During rain events the increased volume of fast moving stormwater carries a range of pollutants into waterways.
One of the major sources of stormwater pollution into waterways is sediment run off from building and construction sites. Council runs a compliance and education program to promote erosion and sediment controls on building sites. The following fact sheet has been developed to assist the public and the building industry to better understand their responsibilities in regards to protecting our local waterways.
Other pollutants that are carried in urban runoff include garden fertilisers, dog droppings, leaves and dirty water from car washing. More information on what you can do to reduce your impacts on local lakes is contained in the following fact sheet
These pollutants also contain nutrients that encourages weed and algae growth as well as mosquito breeding. More information on mosquitoes is available at the NSW Health website.
Council conducts a water quality monitoring program to measure the health of our local waterways. The water quality monitoring program has two focuses as follows:
- A public health focus in assessing the suitability of waterways for recreational activities and visual amenity.
- An environmental focus in assessing the state of the waterways in supporting aquatic life.
