ABSTRACT

Introduction The disposal of foul water and rainwater depends on the proper design of the drainage system and the correct use of appropriate materials. Foul water consists of soil (from WCs), and waste (from baths, basins and sinks). The drainage system should be able to carry and discharge its contents quickly and efficiently in such a way as to avoid damage to health. The system must avoid leakage, resist the entry of substances and avoid blockages. This chapter is divided into three sections:

• above ground drainage • below ground drainage • rainwater disposal.
