Join us for this two part series looking at the theory of sediment basin design and the coagulation and flocculation process relating to the treatment of dirty water. This is a mini online version of the popular IECA Australasia Chapter “Get Flocced” workshops.

The Recent Evolution of Sediment Basin Design in Australia: Presented by Kyle Robson
In 2018 the IECA Australasian Chapter published an update to ‘Appendix B – Sediment Basins’ of their Best Practice Erosion and Sediment Control (BPESC) document. The revision detailed a significant shift in sediment basin design and operation in Australia to a flow-through approach with the aid of coagulants and flocculants adopted from our New Zealand neighbours across the ditch.
This webinar will provide an overview of the changes, why they occurred, what this looks like from a design and construction perspective, and where to find resources to transition designs to comply with the BPESC document. Although this session focuses on Australian practices, other regions can learn improved sediment capture approaches that have been adopted in New Zealand and Australia.
Sediment Basin Design Specifications, Science and Standards in United States of America: Presented by Jaime Schussler
In the U.S., sediment basins are typically employed along the edge of disturbed watersheds to detain stormwater runoff and capture sediment by providing storage to promote gravitational sedimentation thereby reducing offsite sediment discharge. Sediment basins act as a final opportunity to capture sediment laden discharge prior to leaving the site. Design specifications and adequacy vary from state to state. This presentation will cover a wide range of commonly implemented sediment basin design specifications, sediment basin performance evaluations and science-based design, and recap the recently developed IECA Sediment Basin Design Standard.
