Drainage Design (Foul and Surface Water)

The course will enable delegates to develop a deeper understanding of the design of foul and surface water sewers:

• Determine foul flows
• Understand rainfall theory and use it to determine surface water flows
• ” Designing to ‘Sewers for Adoption’ and ‘deemed to satisfy’ criteria.
• Understand how bedding factors can be used for the determination of pipe strength requirements
• Outline some rehabilitation systems and sewer maintenance techniques

At the end of the Course Delegates will:

• have an understanding of how to calculate foul and surface water flows in sewers;
• have an appreciation of the hydraulics of pipe flow;
• be able to size pipes for given flows;
• understand how to determine pipe strengths for different locations.
• Appreciate the dangers associated with working in sewers.

The course will comprise:

• Historic context and legislation – who is responsible for what
• Gravity sewer hydraulics
• Foul flows
• Surface water flows
• Designing to Sewers for Adoption
• Pipe strength calculations
• Sewer maintenance and rehabilitation

Please note:  The design of SuDS is not covered in any depth on this course – please refer to our one day introductory course on the Engineering Aspects of SuDS for more information.

• Assessment of needs and capabilities of delegates
• Presentation by tutor using PowerPoint, with illustrations and photographs
• Several group or individual exercises
• Summary

• Understanding the sources of sewer flows
• Design process foul and surface water sewers, including deemed to satisfy criteria.
• Understand how sewers can be rehabilitated and maintained.

• Civils Graduates or Earth Science Graduates with some basic understanding of hydrology/hydraulics
• Graduate Engineers and Technicians who are involved in the design of large and small foul and surface water sewers
• The course requires some mathematical ability

Delegates should bring scientific calculators and scale rules with them.
