Drainage - An Introduction
This course is targeted at construction professionals to raise their awareness, knowledge and understanding of drainage.
The course will examine the various aspects which can affect the performance of existing drainage networks and issues associated with constructing new systems This will include the basic principles of the design in so far as they can affect the construction and ultimate performance of new and existing systems.
Aims & Objectives:
The course will enable delegates to develop a deeper understanding of the construction and function of foul and surface water sewers and help delegates to:
- Identify typical examples of above and below ground drainage systems;
- Identify and understand the operation of different components within a drainage system;
- Understand how to undertake a survey of an existing drainage system,
- Understand the parameters that are required to design a new drainage system;
- Consider, in the context of drainage, health and safety, workmanship and testing;
- Understand the options available to maintain or rehabilitate drainage systems;
- Gain an appreciation of Sustainable Drainage Systems.
The course will include:
- A brief history of sewers
- Types of drainage systems (foul water, storm water, pumped systems, land drainage)
