Designing a Sanitation System
Considerations
To design a robust system you need to consider:
o What goes in
o What comes out
o What needs to be collected, stored, transported, processed, disposed of
o What technologies can perform the required tasks
o How the required technologies can be linked together (compatibility)
Further considerations:
o Existing infrastructure &
services
o Operation & maintenance
(O&M) requirements
o Lifecycle cost
