Particularly in rural and peri-urban areas where space availability andpopulation density are not constraining factors on its adoption and where onsite sanitation can be substantiallycheaper and easier to promote than sewerage networks.Sanitation systems can be divided into ‘onsite’ and ‘offsite’ technologies. Onsite sanitation systems aim tocontain human excreta at the point of generation (the household level). Onsite sanitation can be classified intotwo main categories: ‘wet’ which require water for flushing; and ‘dry’ which do not require any water forflushing. This type of infrastructure comprises of (improved) latrines, septic tanks and other household leveltechnologies that do not involve sewerage.Offsite sanitation systems transport human excreta to another location for treatment, disposal or use. Offsitesanitation can be classified into two main categories: ‘decentralised’ and ‘centralised’. Decentralised systemsinclude systems where groups of two or more houses are linked to a (small bore sewer) network leading to acommunal treatment system. Wastewater systems serving one or several communities are termed centralisedsystems.Decentralised systems represent an appropriate technological option for urban areas that face problems withhigh population density but where financing for larger centralised treatment systems is not available.More info resourcesHere is a selection of other info resource on on-site sanitation options that go beyond technology we have onour site:What is on-site sanitation?

In this 2004 document the concept of on-site sanitation will be described, followed by the description ofdifferent types of latrines.

However, collaboration is not easy.The scarcity of existing partnerships for sanitation implies that they are even more difficult to build and tomaintain than in other sectors. The diversity that characterises sanitation calls for particular attention toprocess, careful consideration of context, and strong analysis of the framework within which they can operate.This 2006 paper is based on studies in five African cities.Some concrete conclusions are:* Too little attention is paid to the fact that on-site facilities are typically only one link in a broader chain ofwaste removal and treatment.* For the public goods of sanitation to become a reality, public subsidies will be often be needed. Thesesubsidies need to reinforce rather than undermine the private and provider’s goods.* Manual latrine emptying needs to become a recognised part of broader solutions and the health risks must bemitigated.* Solid waste offers interesting parallels for on-site sanitation but disaggregated demand remains a keychallenge.* Sludge transfer and disposal are key bottlenecks to delivering a viable sanitation system.* Partnerships may offer one way of reconciling the links needed, but sanitation offers challenges distinct fromeither water or solid waste.BPD Harnessing Sanitation partnerships_BPD.pdf (1.21 MB), free downloadableformhttp://www.irc.nl/redir/content/download/143704/456922/file/BPD%20Harnessing%20Sanitation%20partnerships_BPD.pdfSmart sanitation solutionsSmart sanitation solutions is a more pictorial booklet that is freely downloadable from our site:
