The sediment basin design course will provide attendees with valuable design, construction and operational insight into sediment basins including the newly adopted Type A, B & D basins. Aspects covered will include how to size sediment basin varieties (including using Topo’s design tool), how to select appropriate coagulants and flocculants, how to maximise basin performance and efficiency and how to adapt to constrained site conditions.

This course has been developed to support the finalised Appendix B (IECA, 2018) document and updated State Planning Policy (Qld). Attendees will gain an in-depth understanding of key design and operational parameters. The course will also provide guidance on construction and operation of Type A, B & D sediment basins, building on performance assessment and troubleshooting tools provided in the Appendix B document.


Each attendee will be supplied with a jar testing kit to assist in selection and use of coagulants and flocculants. In addition, attendees will be provided with a sediment basin sizing tool to assist in basin design tasks. Content and discussion during the course will include expert experience to assist designers and operators in improving design and effectiveness of sediment basins whilst reducing risk and cost.

Content

DELIVERY (1 DAY)

INTRODUCTION

  • What are the current basin standards      specified within various specifications and guidelines and what do they      mean for your site

  • Understanding what the new standards mean      (80th%ile five day event Vs 80% hydrological effectiveness)

  • Overview of sediment basin options (Type A,      B & D)

  • Basin selection and design triggers

BASIN DESIGN

  • Process for sizing Type A, B and D sediment      basins

  • Designing basin inlet arrangements,      including forebays and level spreaders, as well as basin outlets,      including decants and spillways

  • Discussion of key design parameters to      maximise performance and reduce potential for resuspension and      short-circuiting, including clear water zone and baffles

  • +  Comparison of sizing for Type A, B and D basins

COAGULANTS AND FLOCCULANTS

  • Coagulation and flocculation process,      product options available, effectiveness and toxicity risks and management

  • How to undertake a jar test and determine dose      rate (attendee excercise to perform jar tests)

  • Active and passive dosing, including      automated dosing options

BASIN OPERATION

  • Dosing systems (rainfall activated Vs flow      activated)

  • Adaptive      management and trouble shooting

  • Retro fitting existing basins & storage      structures, and final basin decommissioning

Who should attend?

This course has been specifically designed for practitioners responsible for the design and/or construction of sediment basins, including, but not limited to:

  • Site Supervisors

  • Environmental Advisors

  • Engineers

  • Project Managers

Summary

Attendees will gain:

  • Understanding of current construction phase      sediment control standards, per updated SPP (Qld) and Appendix B

  • Appreciation of design inputs and process      for sizing Type A, B and D sediment basins

  • Ability to size Type A, B and D sediment      basins using Topo’s sediment basin sizing tool

  • Understanding of key design considerations      to maximise basin performance and efficiency, including basin      configuration and use of baffles and flow controls structures

  • Improved knowledge of basin construction and      operational aspects to improve effectiveness and reduce cost and risk

  • Skills and tools to select coagulants and      flocculants suitable for site conditions

  • Ability to monitor basin performance and      implement adaptive management to trouble shoot poor performance
