IPWEAQ

This course is identified as advanced training and design for those who have completed the Level 1 & 2 courses. Attendees will gain knowledge and skills to develop and/or assess an Erosion and Sediment Control (ESC) plan against the requirements of the IECA 2008 “Best Practice Erosion and Sediment Control” guideline.

This 3 day course will also address the theory component for candidates wishing to complete the IECA assessment requirements (fundamentals exam and take home plan preparation assignment) to attain CPESC qualification.

This course has been specifically designed for people tasked with preparing, implementing or assessing erosion and sediment control plans, including, but not limited to:

• Planners
• Designers
• Auditors

Attendees must have an existing understanding and experience with erosion and sediment control. 

A base level of knowledge surrounding soils and the fundamentals of hydrology and hydraulics is preferable.

SEDIMENT BASIN DESIGN

The Type A, B & D Sediment Basin Design Course has been developed to support the draft Appendix B (IECA, 2016) document and updated State Planning Policy (Qld).

This forms 1 day of the 3 day course and is focussed at practitioners responsible for the design and/or construction of sediment basins.

• Knowledge of the IECA (2008) Best Practice Erosion and Sediment Control Manual
• Awareness of the impacts of poor onsite ESC management on receiving                     environment
• An understanding of relevant legislation and requirements
• Knowledge of soil types, properties and management techniques
• An awareness of current best practice for managing ESC & the                                     associated limitations
• An appreciation of the effectiveness different erosion & sediment control                   techniques
• An understanding of construction and maintenance requirements for                         control measures (including cost control, resource planning and onsite efficiency)

ADVANCED TRAINING 

• An understanding of construction site hydrology and hydraulics
• Knowledge of sediment basin design and operation
• An understanding of how to achieving successful revegetation on all sites
• An awareness of water quality monitoring (turbidity, TSS, pH)
• Knowledge of inspection and auditing requirements
• An understanding of ESC plan preparation process
