    Safe faecal sludge emptying and transport: compliance challenges and models for a public good
    (IWA Publishing, 2025-05-01) Grisaffi, Claire; Leinster, Paul; Mugo, Kariuki; Drabble, Sam; Parker, Alison
    In the 81 countries where most urban dwellers rely on faecal sludge (FS) emptying and transport, services are frequently provided by a heterogeneous private sector. Considering the responses of service providers is essential to ensuring that the regulatory frameworks put into place achieve their intended outcomes and safeguard public and environmental health. Combining a literature review and expert practitioner input, we identify priority challenges for scaling safe FS emptying and transport (E&T) services and use these to adapt a holistic model of business compliance. We confirm well-documented challenges such as cost structures for compliance with regulation, the perception of services as low status, and an inadequate enabling environment. We identify the importance of trust in building voluntary compliance as a novel issue for sanitation but widely discussed in the regulation literature. We also identify a distinct role for the regulator as a catalyst for change. The role of disgust as a policy barrier and the application of behavioural theory to building compliance are areas warranting further research. This is the first paper to explicitly consider the regulation of FS E&T through a compliance lens, linking established areas of the regulation literature to new findings in urban sanitation.

    Transforming citywide sanitation provision: utility voices on pit emptying and transport services in Kenya and Zambia
    (2022-12-23) Grisaffi, Claire; Oluoch, Priscillah; Hamuchenje, Eustakia M.; Phiri, Jessica; Salano, Gertrude; Hawkes, Lisa; Parker, Alison
    This paper documents the key challenges faced by utilities in sub-Saharan Africa attempting to establish citywide safe manual and semi-mechanized latrine pit emptying, transport and disposal services. The research aims to take a snapshot of utilities at a pivotal point in service development, where initial services have been piloted and the utilities are looking to go to scale. We use the CWIS framework to guide analysis of perspectives of the implementing agencies in Livingstone, Zambia, and Malindi, Kenya, using a secondary data review and 34 key informant interviews. This paper confirms previous findings around the high cost of safe sanitation services in low-income areas, the barriers of emptiability, the engagement of manual pit emptiers and the requirement for investment in supporting systems. Areas for future research were identified, including approaches for service delivery to reduce the decision load on the household, structures of engagement and regulation of pit emptiers, and finally how regulation could support incremental improvements toward full coverage, including the lowest income households. The research documents, for the first time in the region, the challenges of dealing with disgust in establishing these new services and the conflicting role of public utilities as both commercial and social organizations. The current model for private sector delivery of the service is politically viable and reduces the risk and cost burden on the utilities. However, it is likely to leave the utilities unable to scale sanitation to low-income areas.
