Drainage can be roughly divided into two categories: surface water drainage, which is designed to dispose of rain and excess ground water, and foul water drainage designed to dispose of sewage. The design of each is based on the same hydraulic principles. In this chapter we shall concentrate on surface water drainage, indicating the differences between foul and surface water when appropriate. The chapter begins by considering a simplified method of design and goes on to look at construction and some recent developments in trenchless technology. This chapter must be considered as an introduction to drainage design; more detailed information is available from the references made within the text, from the manufacturers and from the Water Research Council.
