IECA are proud to release the updated Best Practice Erosion & Sediment Control for building and construction sites (BPESC).
Originally published in 2008, the BPESC has been periodically updated to ensure that the document remains current and continues to serve as an essential reference for best practice ESC planning and management within Australia.
The 2025 version captures a range of updates, user feedback, and amendments made since the original publication in 2008.
This version provides an up to date, user friendly resource that reflects current terminology and climate changes.
Key changes to the 2025 version include:
- Consolidation into a single document (no longer 3 books)
- Inclusion of Appendix P within the main document
- Updated rainfall terminology consistent with the Bureau of Meteorology and Australian Rainfall and Runoff
- Updated and additional rainfall design values
- Updated rainfall erosivity (R-factors) values
- Consistent sediment control standard
- Additional guidance regarding soil binders, Type B basin dewatering and stockpile management
- Revised soil loss limit for catchments greater than 10,000m2
Books 4-6 remain unchanged at this stage but may be revised in the future to align with the update introduced in this edition.
We trust that you will find the 2025 edition a valuable and practical resource and encourage its continued use to support best practice in erosion and sediment control across Australia.
This update builds upon the original document authored by Grant Witheridge in consultation with industry peers and subject matter experts.
Together, these contributions form a comprehensive national reference for erosion and sediment control best practice.
Historically, strategies for the reduction of soil erosion and land degradation have primarily been developed by the agricultural sector and soil scientists.
However, soil erosion and land degradation is not restricted to just agricultural areas.
Uncontrolled sedimentation, pollution and hydrological changes resulting from construction sites are one of the largest contributors to land and water quality degradation in Australia.
The BPESC demonstrates the important role that engineers, ecologists, civil contractors, and other professionals now play in advancing effective erosion and sediment control.
It provides the strategies and techniques necessary to minimise land and water degradation caused by uncontrolled erosion and sedimentation.
Best Practice Erosion and Sediment Control is an essential national reference for all professionals engaged in erosion and sediment control.
