Training Course H:
Checking and Auditing WinDes Submissions
A course designed to help checking/development control engineers to assess a Win Des ® submission.

Who will benefit? All engineers checking drainage networks for compliance with SFA, the Interim Code of Practice for SUDS, the Code for Sustainable Homes, Climate Change and Exceedance. A good practical knowledge of Win Des is required.

What will they learn? The impact of a new development upon the existing catchment is a key aspect of this course, which covers determining greenfield runoff, SUDS feasibility, storage estimates, hydraulic performance and a full range of testing from minimum pipe diameters to self-cleansing velocities.

Key Topics WinDes functions covered include:

· Auditing to the Interim Code of Practice for SUDS & Code for Sustainable Homes:

• Ascertain greenfield runoff rates
• Check greenfield volume balance

· SUDS Feasibility

• Assessing the viability of SUDS
• Anticipating storage volumes for a development

· Auditing to comply with current standards to identify:

• Critical storm durations
• No flooding for 30 year return period
• Identify indicative flood flow paths for extreme return periods, accounting for climate change
• Check the depth, direction and velocity of overland flood routing

The course combines tutorials and training notes with hands-on exercises and tutor-led worked examples. Please note that this course has been developed for checking/development control engineers and contains elements of courses C, F & G.
