Erosion and Sediment Control (ESC)
At Biostream Environmental, our expertise in Water Sensitive Urban Design (WSUD) assets highlights the critical importance of identifying erosion and sediment control (ESC) issues across development construction and domestic housing sites.
WSUD assets are among the most vulnerable and expensive components within a development, and are highly susceptible to failure where ESC is not effectively managed. These issues have the potential to damage and compromise asset performance if not identified early.
By identifying risks early and implementing proactive ESC measures, we minimise impacts to both the asset and sensitive downstream waterways. This approach has consistently reduced the need for costly rectification works, avoided full asset rebuilds, and delivered significant savings to both developers and local government authorities, reinforcing our commitment to sustainable and practical environmental outcomes.
Through close collaboration with local teams and stakeholders, we develop and implement targeted ESC strategies that protect both asset performance and environmental outcomes. These include:
Conducting detailed site assessments and risk evaluations
Implementing effective erosion and sediment control measures
Assessing the installation and compliance of ESC systems
Monitoring the ongoing performance and maintenance of ESC controls
These initiatives reduce the risk of WSUD asset failure, minimise environmental impact, and help avoid costly rectification works, contributing to more sustainable and responsible development outcomes.
Examples:
Upstream ESC measures not capable of minimising highly dispersive sediments entering and compromising WSUD assets constructed prior to 80% development buildout.
1. Before rain event:
2. During rain event:
3. Impacts on constructed WSUD asset following rain event:
Dispersive sediment layer over the top of the bio media ultimately required the removal of the plants and top 150mm of bio media, the 3 basins then had sacrificial turf layers installed – as seen in two of the photos significant volumes of highly dispersive sediments escaped into downstream eco systems - this situation also became a very costly yet avoidable situation for the developer.
