Development is not just about factories, agricultural productivity and urbanisation. There are also important requirements for people’s everyday lives, health and wellbeing. The provision of clean water and adequate sanitation facilities are among the main priorities (Inset 1).
At a basic level, each person needs only 20–30 litres of water per day, and only about 3 litres of this has to be clean enough to drink. It is therefore amazing that so many human beings are still without access to basic sanitation and clean water. The technology has been available for decades. For example pit latrines are easy to design and build and have even been used at the Glastonbury Festival.
