Pre-planning Construction Activities to Prevent Water Pollution at Construction Sites

1:30 to 2:00 pm
Businesses, governments, conservation bodies and members of the public are becoming increasingly concerned about the detrimental environmental impact that the discharge of silty waters is having on the quality and bi-diversity of our inland water ways.
Poorly planned construction works are a major source of silty water. Construction sites need to adequately pre-plan their works to minimise both the volume of “dirty” silty water that is generated and prevent the release of sub-standard water into the environment. A “suck it and see” approach to the implementation of treatment solutions is not acceptable.
Protection of the aquatic environment is achieved by the correct implementation of an appropriate treatment system. For construction sites, a variety of treatment solutions of increasing complexity: Prevention; Erosion Control; Sedimentation Control; Active Treatment may be adopted.
For any site a number of key factors need to be taken into consideration: Site Area, Slope, Soil Type, Annual Rainfall, and Environmental Sensitivity. The interplay of these factors needs to be understood to ensure that the correct treatment solution is implemented.
Pre-planning of Construction Activities is essential to ensure that the subsequent site works have minimal impact on the aquatic environment, ensuring the quality and biodiversity of our inland waterways.
1. To understand the Treatment Hierarchy and what types of treatment solutions fit into each Tier:
• Tier 1. Prevention elimination
• Tier 2. Erosion Control
• Tier 3. Sedimentation Control
• Tier 4. Active Treatment
2. To understand the key site factors (drainage area, slope, rainfall, and ground conditions) which control the potential for “Dirty Water” to be generated and how these factors affect the volume of run-off generated.
3. To understand how the Environmental Sensitivity (Environmental Risk) of the Site Area affects the effects the amount of site effort (expenditure) that needs to be implemented.
