Further Description / Program

*** Veuillez trouver la version française ci-dessous***

Almost three billion households worldwide use non-sewered sanitation systems—septic tanks and latrines, which eventually fill up.

In urban areas, there is no room to dig a new pit, so pit latrines must be emptied regularly.

In Uganda, for instance, 95% of the households use onsite sanitation facilities. Most of the households in unplanned settlements have neither bins nor incinerators. Solid waste such as menstrual pads is directly thrown into pits. Menstrual products are designed to swell to absorb liquids, thus risking blocking sewage pipes. Sanitation companies around the world report that menstrual products are involved in 80-90% of these blockages.

In Burkina Faso, the access to facilities with improved excreta management increased from 11% in 2010 to 22% in 2019, thanks to the efforts by the government and its partners. However, also here solid waste such as bottles and plastic bags is thrown into the latrines.

This leads to rapidly filling pits, which are difficult to empty and thus bring about high emptying costs. Sludge removed from pit latrines may be treated and reused as fertilizer. Waste-heavy sludge however is challenging to transport, and solids such as menstrual waste need to be removed by sanitation workers before the treatment process.

This webinar brings together two GIZ programmes working on access to safe sanitation along the entire sanitation service chain: Scaling up of Drinking Water and Sanitation Supply in Burkina Faso and Sanitation for Millions (project component Uganda).

Joined by the Rwandan sanitation logistics company Pit Vidura, implementing experts from the three countries will discuss the following questions and present their experiences from the field:

Behaviour: Why do users throw solid waste such as used menstrual pads into pits?
Best practices: What alternative user-friendly solutions are out there?
Learnings: How to remove faecal sludge from pits when it is mixed with non-biodegradable solid waste?

Speakers:
Shurstine Somé, GIZ programme Burkina Faso
Aubrey Simwambi, BORDA Zambia
Faithful Atusinguza, GIZ programme Uganda
Moderation: Alice Brandt, GIZ Sanitation for Millions

This webinar will be held in both English and French. To register for the English channel, please follow this link:

Un problème solide, de vraies solutions? Comment traiter les déchets non organiques dans les latrines à fosse?
Expériences du Burkina Faso, de l'Ouganda et du Rwanda

Près de trois milliards de ménages dans le monde utilisent des systèmes d'assainissement sans égouts - fosses septiques et latrines, qui finissent par se remplir.

Dans les zones urbaines, il n'y a pas de place pour creuser une nouvelle fosse, donc les latrines à fosse doivent être vidées régulièrement.

En Ouganda, par exemple, 95 % des ménages utilisent des installations sanitaires sur place. La plupart des ménages vivant dans des campements non planifiés n'ont ni poubelles ni incinérateurs. Les déchets solides tels que les serviettes hygiéniques sont directement jetés dans les fosses. Les produits menstruels sont conçus pour gonfler afin d'absorber les liquides, risquant ainsi de bloquer les canalisations d'égout. Les entreprises d'assainissement du monde entier rapportent que les produits menstruels sont impliqués dans 80 à 90 % de ces blocages.

Au Burkina Faso, l'accès à des installations permettant une meilleure gestion des excréments est passé de 11% en 2010 à 22% en 2019, grâce aux efforts du gouvernement et de ses partenaires. Cependant, ici aussi, les déchets solides tels que les bouteilles et les sacs en plastique sont jetés dans les latrines.
Cela conduit à un remplissage rapide des fosses, qui sont difficiles à vider et entraînent donc des coûts de vidange élevés. Les boues retirées des latrines à fosse peuvent être traitées et réutilisées comme engrais.

Les boues lourdes sont cependant difficiles à transporter, et les solides tels que les déchets menstruels doivent être enlevés par les agents d'assainissement avant le processus de traitement.

Ce webinaire réunit deux programmes de GIZ travaillant sur l'accès à un assainissement sûr tout au long de la chaîne des services d'assainissement : Mise à l'échelle de l'approvisionnement en eau potable et de l'assainissement au Burkina Faso et de Sanitation for Millions (composante Ouganda du projet).

En compagnie de l'entreprise rwandaise de logistique de l'assainissement Pit Vidura, des experts de mise en œuvre des trois pays discuteront des questions suivantes et présenteront leurs expériences sur le terrain :

Comportement: Pourquoi les utilisateurs jettent-ils des déchets solides tels que des serviettes hygiéniques usagées dans des fosses?
Meilleures pratiques: Quelles sont les alternatives conviviales qui existent?
Apprentissages: Comment enlever et traiter les boues fécales des fosses lorsqu'elles sont mélangées à des déchets non biodégradables?

Les conférencières :
Shurstine Somé, programme GIZ Burkina Faso
Aubrey Simwambi, BORDA Zambia
Faithful Atusinguza, programme de la GIZ Ouganda
