Even though increased access to improved sanitation is called out as a United Nations Millennium Development Goal, progress has been spotty. For instance, in Haiti sanitation coverage actually declined between 1990 and 2010, from 24% to 17%. The overall objective of the work performed for this project is to refine the design of an outdoor latrine system (the “arborloo”) in order to make it suitable as a commercial product in rural areas of developing countries. Widespread adoption of such devices could dramatically improve the sanitation of rural 3 communities and the health of their residents. In addition, local manufacture and maintenance of the arborloos can provide economic opportunities to the residents of these rural communities. The work undertaken in the course of this project included the following: A systematic literature review on sanitation implementation case studies was performed. The cases were evaluated to identify barriers to adoption and sustained use of sanitation technologies. Results from this review informed the system designs that followed. Two multidisciplinary teams of engineering students designed a total of four prototype arborloo bases and tested them according to engineering requirements that they developed from an assessment of customer. One team focused on the development of inexpensive and lightweight concrete bases while the other team worked to develop an inexpensive plastic base. Each team followed the engineering design process including activities of project planning, needs assessment, writing engineering requirements, functional decomposition, brainstorming, feasibility analysis, development of a complete design drawing package with bill of materials, writing test plans, and construction and testing of prototypes against specifications. Each team was able to complete a process based lifecycle assessment of their prototype designs. These assessments describe the environmental impacts that arise across the lifespans of the bases as currently designed. The results from these lifecycle assessments serve as baselines, and enable the identification of opportunities to improve the environmental performance of the bases in subsequent trials. As they moved through the design process, the student teams also managed risks, tracked problems and documented their work on RIT’s Edge website throughout the year-long course. A multidisciplinary design team worked to develop a wind testing protocol that could be used to test the robustness of the arborloo structure to the high wind conditions prevalent in rural areas of Haiti. They followed the same design and documentation procedures as the teams described above. A faculty/student team from RIT was able to travel to Haiti and work in support of this project. The team met with our Haitian partner organization to conduct a series of focus groups related to the social and economic acceptability of the arborloo with local community organizations. They were also able to retrieve information about the preferences of local residents for various arborloo design characteristics like color and shape. Summary of Findings: Literature review of case studies: A total of 53 reports were reviewed to help identify barriers to adoption and sustained use of sanitation technologies in developing environments. The cases were divided into sanitation projects that achieved their goals of improving sanitation and those that did not achieve the stated goals or that achieved them but with unacceptable risks. All cases were examined to determine the critical issues that impacted the success of implementation. The review suggested that slow expansion of sanitation coverage globally is not simply due to lack of attention, but is also impacted by unaddressed social, economic, technical and environmental 4 barriers. Factors that prevented implementation strategies from succeeding generally fell into two categories: Technical failures including the malfunction of the technology related to infrastructure deficiencies and the design being ill-suited to the environment in which it was applied. User-acceptability related failures such as lack of adoption, discontinued use and misuse of the technology related to social and economic issues. This review led to the drafting of a series of guidelines for designing and deploying improved sanitation systems in developing environments (see body of report). These guidelines served as basic reference material for the design and development work that followed. Concrete base prototyping: A multidisciplinary engineering design team was charged with the task of developing an improved concrete arborloo base. The team developed and prioritized potential customer needs, and evaluated various concrete formulations and concrete base designs against those customer needs. The team’s concrete mix experiments culminated with the development of a concrete mix that uses material locally available in Haiti to ensure strength while being much lighter than standard concrete. The recipe blends Portland cement, sand, broken coconut shells, waste Styrofoam, Glenium (a performance enhancing water reducer), and coconut fibers for reinforcement. Plastic base prototyping: A multidisciplinary engineering team was charged with the task of developing and prototyping a plastic base system suitable for arborloos. The team examined currently available solutions (bread crates, plastic milk crates) that could be modified for use as an arborloo base. In addition, they explored processes for forming plastics into new shapes. The team constructed prototypes of both types. The “deckloo” is a prototype constructed from

    The Animal Improved Dung (AID) plus seeds treatment. Managing livestock, dung beetles and earthworms to disperse rock dusts, fertilizers, beneficial micro- organisms, biochar and seeds to grow forests and food, improve soils and fix carbon and climate. Summary The AID plus seeds treatment is a system of innovations which hastens and enhances succession, increases soil carbon and fertility and grows high biomass vegetation. Soil improvers such as rock dusts, spores of beneficial micro-organisms, mineral fertilizers, biochar and burnt bone (from home-made fuel-efficient stoves) and seeds of fast- growing, deep-rooted plants can be fed to livestock to disperse in their manure. Dung beetles, earthworms and termites further disperse and incorporate the improved dung into the soil and increase the availability of nutrients, while their tunnels improve soil structure including air and water infiltration and root growth. Livestock in a planned grazing system can be used to treat/seed areas such as pastures, orchards, plantations, vegetable garden fallows and to reafforest degraded land. The resulting vegetation produces food and fodder, timber (carbon stored for hundreds of years), and fuel wood which produces charcoal (carbon stored in soil for possibly thousands of years), improves soil by promoting the growth of soil life and adding carbon, reduces erosion, as well as increasing transpiration, cloud formation and precipitation. “...increasing agricultural productivity would not only reduce conversion of wild land to new cropland, but it could return existing cropland back to nature. Increasing agricultural productivity is the single most effective method of preventing habitat loss and fragmentation, and conserving global forests, terrestrial biodiversity and carbon stocks and sinks”.

  • The Arborloo
    The Arborloo The latrine that becomes a tree! A guide for latrine construction and tree planting Peter Morgan Introduction The Arborloo is a nothing more or less than a simple pit latrine. But it differs in several fundamental ways in its design and the way it is used from the commonly used deep pit latrine. *All the parts of the Arborloo, apart from the pit, are portable. This includes the “ring beam” protecting the pit head, the concrete slab and the superstructure. Each of these components moves on a “never ending journey” from one pit to the next at about one yearly intervals. The latrine is literally picked up and moved, leaving the almost filled pit behind. * Arborloo pits are shallow, - no more than one metre deep and they are not lined with bricks or other materials. The pit is normally protected at the head with a “ring beam” made of bricks or concrete which strengthens the pit head and reduces the effects of erosion and pit flooding from rainwater. In very sandy soils, a 200 litre drum may be used to make a pit lining. *Soil, wood ash and leaves are added regularly to the pit in addition to excreta. These aid the composting process considerably. The remarkable conversion from excreta into humus, is normally complete well within 12 months of closing off the pit. The addition of soil and ash on a regular basis also reduce fly and odour nuisance. * The Arborloo pit is NOT used as a dumping ground for rubbish like most pit latrines. The dumping of plastic, bottles and rags etc, is not recommended.

  • Chapter 8: Sanitation and Hygiene 1
    Chapter 8: Sanitation and Hygiene 1 This chapter focuses on sanitation and hygiene factors for preppers. Its primary focus is on the disposal of human effluent. On average a person produces 128 grams or a little over one quarter of a pound of fecal matter a day. Fecal matter is nutrient rich and eventually it is converted into compost by bacteria and microorganisms where its nutrients are recycled into the soil. It is a matter where and how this decomposition occurs. Unfortunately, fecal matter is also a source of disease that can be transmitted to other people if care is not taken. For preppers, there are essentially three approaches to disposing of human effluent. The first method is to decompose it onsite. The hot and cold composting approaches are examples of this approach. The second approach is to store it and transport it to another site where it is decomposed. The vault systems typify this approach. The third approach is to flush it where it is transported to another site for decomposition. There is no onsite storage of the human effluent. Central sewage treatment plants exemplify this approach. For most preppers, disposal of human effluent is determined by the existing facilities being used, whether those facilities work, and the length or duration of the crisis situation. For homesteaders using a composting toilet or outhouse, most likely continue using their outhouse or composting toilet in a crisis situation. People on a septic system will most likely continue using their septic system during a crisis situation. However, they may need to add an external water source to operate the system.

    MANGWENDE ORPHAN CARE TRUST Concept Design Proposal “The future of all people is linked with the condition of the land. If the people enrich the land the land will enrich them in return. Permaculture gives a way of redesigning our communities, cities and habitats in a way that enhances nature our local economies and a healthy lifestyle. If applied correctly, permaculture design can be used to solve many if not all our planets and species current problems.” Evans Mangwende Case study by Viktoria Szilvas, Nadia Khuzayim, Eve Allemand and Tilla Theiss GEDS Design Studio 2019 1 GEDS Design Studio 2019 - Mangwende Case Study Report EXECUTIVE SUMMARY Economic, social and environmental issues are interlinked and so require a common worldview to tackle them in an integrated way in order to address the questions of climate change and sustainability so that the needs of individuals, communities and the planet are met without compromising the conditions of survival for present and future life. While there is a pressing call to reduce worldwide consumerism, energy consumption, carbon emissions, and wastage of water and other natural resources, there are also a number of issues associated with rural disadvantaged communities in Zimbabwe with regards to the financial burden and the lack of access to appropriate education on sustainable practices. The mechanistic, reductionist and linear economic system destroyed the ecosystem and social integrity. Moving away from this dysfunctional pattern incentivises the emergence of an alternative mode of thinking and behaving, respectful of the intrinsic environmental and human rights. This way, nature and people can coexist to mutually profit from a thriving livelihood and long term viability.
