The course is based on "Urban Drainage" by David Butler and John W Davies. The design of foul and surface water sewerage systems requires knowledge of many different characteristics of the drainage area or catchment. This course provides an outline of the information required and where this may be obtained. The course covers the sources of flows; gravity sewer hydraulics; foul and surface water flows; attenuation systems are briefly covered; designing to "Sewers for Adoption"; pipe strength calculations; and maintenance and rehabilitation.
Aims & Objectives:
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
Learning outcomes:
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.
Course Outline:

Summary
Benefits Perceived by Participants:
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.
Intended for:
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.
Pre-Course Requirements
Delegates should bring scientific calculators and scale rules with them.
