===Background===
==== Development of the sanitation ladder====
*Target 6.1 by 2030, achieve universal and equitable access to safe and affordable drinking water for all
*Target 6.2 by 2030, achieve access to adequate and equitable sanitation and hygiene for all, and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations
==== Pros and cons of the functional sanitation ladder====
*Various organisations have moved forward with the ladder concept, but operationalisation remains problematic
|}
=== Adaptations of the functional sanitation ladder===
*How to approach the different assessment levels, i.e. in areas with varying levels of sanitation service, system boundaries may be set at different levels, for example, the individual project level or city level.
*Further incorporate equity, equality and human rights into the functional sanitation ladder
