Component Descriptors for sanitation systems

Component: A cluster of technologies which have generally similar characteristics, which can deliver the functionality of a single Element of the SVC and which are likely to have similar cost profiles.

Hilighted cells show possible Components that can be part of a complete sanitation system

1 Waste water treatment unit can sometimes incorporated to co-treat faecal sludge transported from on-site sanitation systems. In this case the facility would still be classified as waste water treatment rather than faecal sludge treatment.

2 Conventional sewers use ‘traditional’ hydraulic design approach, usually free flowing and laid under the road network.

3 Simplified sewers use a modified hydraulic design approach. They are smaller diameter and laid at shallower depths than conventional sewers. Network may be laid to follow shortest route subsequently optimising length of pipes.
