Chapter 11. Development

Implementation of a successful sanitation project usually follows a recognizable pattern. After the initial surveys, as described in Chapter 9, a demonstration or experimentation phase is required. The demonstration phase is a practical test of the feasibility of the recommended options. This is followed by a consolidation period (Glennie, 1983), primarily to organize the institutional aspects of the project, leading on to the mobilization or expansion phase, when most of the sanitation facilities are constructed.

For the benefit of the agencies involved, it is always advisable to conclude the project with some form of monitoring or evaluation in order to determine how effective it has been. The time scale can vary according to the size of population to be served, its receptivity to development ideas and the financial resources available. However, it is usual to find that the whole sequence takes years rather than months.
