Résumé:
Communities often face choices ranging from single pit ventilated improved latrines to double ventilated improved pit latrines to urine diversion/composting latrines. These options promote household management of operation and maintenance. (In most cases, the cost of emptying a single pit every five years is estimated at between R35 and a still-affordable R60.) Where higher levels of service are chosen, the costs are a lot higher - as much as R500 per household per annum. The initial capital cost is also dependent on the choice of technology.
One of the lessons learnt from the DWAF programme is that it is possible to provide on-site dry systems for an initial, capital outlay of less than R1000. The Archloo, which is provided to many cholera-affected areas, is an example of a facility that can be provided at a cost of R600 using local materials and local labour - and that can be put into large-scale production. However, such provision must be coupled with health and hygiene promotion if health improvements are to be ensured.
In this document you will read more about the various technical options that meet the requirements for basic sanitation.
These need to be considered within all the sustainability requirements, e.g. affordability, operation and maintenance. The options are divided into two categories: Dry on-plot systems (that do not require water for operation) and wet systems (that do require water for operation).The following information is provided for each technical option described:
• A technical drawing of the recommended option
• A description of the options
• An explanation of the principles of operation
• Operational and institutional requirements
• A summary of costs
• Notes on previous user experiences and comments on these
