This dataset relates to a study exploring off-grid sanitation practices in Kenya, Peru, and South Africa, with a focus on how various user demographics access and utilize sanitation facilities. The study contrasts container-based sanitation with alternative methods. Participants, acting as citizen researchers, gathered confidential information using a specialized mobile application. The primary objective was to uncover obstacles and challenges, with the intention of sharing insights with other municipalities interested in implementing container-based sanitation solutions for off-grid regions. Over the course of 12 months, participants received incentives for consistent involvement, following a micro-payment for micro-tasks model. Selection of participants was randomized, involving attendance at a training session and, if necessary, provision of a smartphone which they retained at the conclusion of the project. Weekly smartphone surveys were conducted in more than 300 households within informal settlements across the three countries throughout the project duration. These surveys aimed to capture daily routines, well-being, income levels, usage of infrastructure services, livelihood or environmental shocks and other socioeconomic factors on a weekly basis, contributing to more comprehensive analyses and informed decision-making processes. The smartphone-based methodology offered an efficient and adaptable means of data collection, facilitating broad coverage across diverse geographical areas and subjects, while promoting regular engagement. Open Data Kit (ODK) tools were utilized to support data collection in resource-limited settings with unreliable connectivity.To protect human health and the environment, sanitation systems must separate people from their excreta and treat it. This does not just involve technologies but other aspects like finance, government policies and human behaviours must be considered. Sewers and wastewater treatment plants can assist in providing safe sanitation, but they are expensive and challenging to build, particularly in dense urban areas or where people do not own the land that they live on. In fact, only 45% of the world's urban population have safely managed sanitation; that is where human waste is treated before disposal. Many of these people are instead using off-grid options for sanitation, such as pit latrines and septic tanks. These are physically difficult to empty, especially in areas of high population density, on steep slopes or with a high water table, and pose significant health hazards. The collected waste is often dumped illegally, frequently into water sources. Off grid solutions can only manage waste safely if the waste collection, treatment and disposal is properly considered. This research will focus on an emerging off-grid sanitation option in the form of container-based sanitation (CBS) across four city contexts where the provision and regulation of CBS is done by different organisations. In Cap Haitien (Haiti), CBS is provided by an NGO, in Lima (Peru) it is provided by a private company, in Cape Town (South Africa) it is provided by the municipality and in Kakuma Refugee camp (Kenya) it is provided by a private company working with an NGO. A refugee camp is included as in the future, refugees driven by climate and other factors will make up a significant proportion of the world's urban population. Interviews will be conducted with the staff working for the CBS provider as well as other organisations that they work closely with, e.g., local government, water utilities and regulators. To capture the feelings and opinions of the people using the CBS toilets, as well as people using other off-grid sanitation options like pit latrines, a novel smartphone data collection will be used. Participants will complete a short survey several times a week to capture aspects of their mental well-being. In addition, the data collected will reveal whether current regulations and policies support CBS and whether CBS increases disparities or decreases them. For example, does CBS without a permanent infrastructure make users feel more vulnerable to eviction, and is the collection of the containers a burden? Or does it give access to people who would not otherwise be able to use a toilet? The project will also look at the links with other sectors, specifically waste, energy, transport and solid waste, as if CBS coverage is increased these services will be impacted. For example CBS relies on road transport and cause additional traffic. But the use of CBS stops the disposal of waste into rivers so water supplies are cleaner. Lessons from the project will be shared with other cities who are thinking about implementing CBS, and with other sectors who are working out how they might deliver their services "off-grid". Co-I's have been identified that have expertise beyond sanitation in urban services, and results will be linked and presented at the GCRF Urban Risk Resilience Hub to look more broadly at lessons for off-grid cities.
High-frequency phone surveys were conducted using ODK software over a yearlong period. Participants received phone ownership, data, and talk time in exchange for completing weekly short questionnaires through a bespoke app. Push notifications were utilized to remind respondents of available tasks, indicating estimated completion time and potential point rewards. Participation was voluntary. Respondents selected tasks within the ODK app, and upon completion, encrypted surveys were stored on a cloud server. Weekly data downloads facilitated analysis of points and points were converted to local currency and distributed weekly to participants. Ethical approval was obtained from relevant bodies, and informed consent was secured from all participants. Compensation was based on the project budget and average cost of mobile phones. Gatekeepers, typically CBS organizations, selected participants who attended training workshops. Ongoing technical support was provided. Surveys were designed by sanitation experts, translated, and pilot tested in each country. Bonus points were awarded to mitigate survey fatigue. Skip logic was employed for efficiency, with skipped questions left blank. Surveys were converted to ODK format, allowing for language customization and training flexibility. The survey schedule included weekly tasks with a one-week expiration, supplemented by monthly tasks. Detailed task information is available in the repository.
