Drainage Design (Foul and Surface Water) All our courses can be offered as in-house training for further details please telephone: 01446 775959 or email: admin@symmonsmadge.co.uk

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:

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

Mode of Delivery:

Assessment of needs and capabilities of delegates

Presentation by tutor using PowerPoint, with illustrations and photographs

Several group or individual exercises


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.

" Delegates should complete the pre-course questionnaire.

Course Duration:

1 day (6 hours) IPD/CPD
