==Health Aspects/Acceptance==
By covering faeces with soil/ash, flies and odours are kept to a minimum. Users may not understand the difference between the Fossa Alterna and a [[Double Ventilated Improved Pit|Double VIP]], although if given the opportunity to use one, people should have a good appreciation of the advantages. Demonstration units can be used to show how easily one can empty a Fossa Alterna in comparison to emptying a Double Pit. Keeping the contents sealed in the pit for the duration of at least one year makes the material safer and easy to handle. The same precautions that are taken when handling compost should be taken with the humus derived from the Fossa Alterna.
==Maintenance==
This [http://www.bvsde.paho.org/bvsacd/cd66/ToiletsCompost/cap4.pdf document] contains a lot of information about building, maintaining a fossa alterna.
