    The potential for scaling up container-based sanitation in informal settlements in Kenya
    (Wiley, 2022-02-21) Mallory, Adrian; Mdee, Anna; Agol, Dorice; Hyde-Smith, Leonie; Kiogora, Domenic; Riungu, Joy; Parker, Alison
    Kenya has enshrined the right to sanitation in the 2010 constitution. Achieving this requires scaling up infrastructure and models of delivery beyond sewer networks that have previously been the focus. In Kenya, two enterprises, Sanergy and Sanivation, have been providing new forms of off-grid services with container-based sanitation (CBS). This paper uses a political economy analysis to understand the incentives, institutions and power dynamics that are enabling or constraining the potential for such off-grid sanitation models. The paper outlines six core problems to be addressed in the pursuit of scaling up: fragmented governance; sustainability of CBS enterprise models; service delivery planning in informal settlements; personal power rather than institutions in decision-making; vested local interests; and land tenure and political connection. It discusses how stakeholders might work collaboratively to progressively address or recognise these issues.

    A qualitative study on resource barriers facing scaled container-based sanitation service chains

    Container-based sanitation (CBS) is an increasingly recognised form of off-grid sanitation provision appropriate for impoverished urban environments. To ensure a safely managed and sustainable service, a managing organisation must implement a service chain that performs robustly and cost-effectively, even with an expanding customer base. These ‘CBS operators’ adopt varying approaches to achieve this objective. Following research including interviews with representatives from six current CBS operators, this paper presents a generalised diagrammatic model of a CBS service chain and discusses the three broad thematic challenges currently faced by these organisations. Supplying cover material is a universal problem with hidden challenges when taking advantage of freely available resources. There is no universally applicable approach for the efficient collection of faecal waste despite the high labour costs of waste collection. The best strategy depends on the CBS operator's overall expansion strategy and the location of fixed features within the served community. Although CBS is technically well-suited to being turned into new products within the circular economy, in practice, this requires a diverse range of skills from CBS operators and is hampered by slow growth in other organic waste recovery services and unhelpful regulation.

    Understanding the role of informal pit emptiers in sanitation in Nairobi through case studies in Mukuru and Kibera settlements
    (IWA Publishing, 2020-12-09) Mallory, Adrian; Omoga, Lilian; Kiogora, Domenic; Riungu, Joy; Kagendi, Dorothy; Parker, Alison
    Achieving universal sanitation in informal settlements will depend on improved onsite sanitation, as sewer systems are unlikely to be viable solutions due to technical and political constraints. In Nairobi, Kenya, 60% of the population live among its 150 informal settlements, occupying only 5% of its total residential land. This research assessed the role of informal pit emptiers in providing sanitation in Mukuru and Kibera, two of the largest informal settlements in Nairobi, and the barriers to achieving improved services. Through qualitative data collection, the research found that pit emptiers are institutionally and physically outside of the current paradigm of sanitation service delivery. There is no infrastructure available to remove waste from informal settlements, except for a transfer station that is being piloted by Sanergy, and instead waste ends up disposed in the community. The pit emptiers also face violence and intimidation from competitors or locals claiming ownership of territory. Providing improved sanitation in such areas will depend on the provision of new infrastructure, but this can only succeed with a detailed understanding of the competing and vested interests that can enable or undermine a project.
