Construction Site Management
South East Queensland’s growing population continues to create demand for new urban land development at a rate of over 2,300 hectares per year*. In urban areas, the mud (or sediment) washed off construction sites is considered to be the most significant source of stormwater pollution impacting upon the health of our waterways.
The process of minimising soil erosion and the release of sediment from land-disturbing activities is called Erosion and Sediment Control (ESC). There are well-established ESC principles and practices for construction sites to follow to minimise their impact and ensure compliance with regulations. The key principles for effective erosion and sediment control include:
- Minimising erosion by managing the area and duration that soil is left exposed to rainfall, and stabilising (covering) the soil as soon as practicable.
- Managing the flow of ‘clean’ stormwater through constructions sites and ensuring that sediment-laden (dirty) stormwater is directed into sediment control devices (traps) for treatment before it leaves the site.
- Trapping sediment in adequate sediment control devices to minimise runoff.
Healthy Waterways provides training to aid local governments and the development industry in reducing the impact of construction sites on waterways and mitigating associated costs. We develop comprehensive guidelines and resources which engage industry and government to improve their capacity to mitigate the impact of land development.

Did you know...
South East Queensland is the fastest-growing region in Australia with the population heading towards eight million by 2044. The increased demand for water supply, infrastructure, recreation and tourism places greater pressures on our waterways.
What is Sediment?
Sediment are particles that are washed off the land into waterways and come in all shapes and sizes - from larger sand particles to smaller mud, clay and silt particles. Too much sediment can cause harm to the plants and animals that live in our waterways.
ESC Tool Kit
Healthy Waterways, together with the Department of Environment and Heritage Protection, has released an online resource to help combat the increasing amount of sediment running off building sites and impacting Queensland’s waterways and communities.
