Designing Sustainable Sanitation for Floating Communities

The document discusses a case study of designing sustainable sanitation options for floating communities in Cambodia. Engineers Without Borders and Live and Learn Environmental Education partnered to develop affordable toilet designs using local materials that treat waste onsite through processes like desiccation and storage. Their goal was to create culturally appropriate and sustainable sanitation solutions. One design they trialed was a three-hole urine diversion desiccation toilet that collects feces dry and stores it with ash for 6 months while diverting urine and wash water. They also built a floating waste management station to trial different treatment methods and integrate waste processing with energy and food production, such as a floating garden trial. Their end goal is a commercially sustainable sanitation system for floating and

- 5. Design Approach Goal was to develop sanitation options that are: culturally appropriate, affordable, sustainable Design requirements: local production, local materials and expertise Holistic considerations from the start: gendered, considered whole of cycle, always working towards self-sustaining market delivery
- 7. 3 Hole Urine Diversion Desiccation Toilet (UDDT) Faeces collected dry in bucket, ash added, stored for 6 months Urine diverted Wash water diverted - from menstrual hygiene and anal cleansing Consumables: soap, ash, water Materials: cement, bowl from market as cover, pvc pipe, reused buckets, wood or metal frame constructed locally Cost: ~35USD
- 8. Floating Community Waste Management Station Built as a demonstration of what is achievable within the Tonle Sap Environment. Designed to: Act as platform for trials of several different treatment methods. Integrate with energy and food production. Desiccation and storage waste treatment process currently under trial.
- 10. Floating Garden Community lead trial using common vegetables. Using the waste management station as a foundation for trial.
- 12. End Goal: Sustainable sanitation for floating communities(and other communities in Challenging Environments) Community lead design and trial UDDT using local materials and methods Waste treatment linked with energy and food production Commercially sustainable Under trial Foundation in place

Notes de l'éditeur
- Thank-you to our community partners. Without them, the project would be impossible.Feedback. If time:MrSokSueng: "Good Sanitation means good MrSokSovann: "My floating toilet is good for my health, is more convenient and private"Mrs Yan Yeoun: "Clean water is important for our health"Ms Lai-Im: Community Liaison Officer"Clean water is the most important thing to our community"PichVongsa: Principle from the PhatSanday Secondary School"Our community wastes money on health care, that we wouldn't need to spend if the water was clean"MrHakleyKe: Teacher at the Secondary School Community Liaison Officer"I want everyone in the community to have a toilet.”
- I would like to come at the end and make a brief comment to advocate for small funding packages over time that allow innovative development without high expenditure. That these can then make large scale processes possible in challenging environments.
- Since 2008, Engineers Without Border Australia has been working with Live & Learn Environmental Education Cambodia, partners and the communities of Phat Sanday to assess, research, develop and trial a sanitation response for communities living in one of these challenging environments, the Floating Communities of the Tonle Sap Lake in Cambodia.
