  • Sustainment and sustainability of the delegated management model of urban water service delivery

    Open Access•Lorna Grace Okotto, Joseph Okotto-Okotto et al.•ARTICLE•Sustainable Futures•2026

    Utility/small-scale service provider partnerships are a pro-poor water service delivery mechanism that also reduce non-revenue water and generate employment. Since 2006, a water utility in Kisumu (Kenya) has operated such a partnership programme, the Delegated Management Model (DMM). Implementation science explicitly examines how setting and individuals’ experiences influence public health programme adaptation, but few studies have applied implem…

  • The impact of the delegated management model of urban piped service delivery on water quality in Kisumu, Kenya

    Open Access•Lorna Grace Okotto, Joseph Okotto-Okotto et al.•ARTICLE•Utilities Policy•2025•Referências: 1

    Delegated management (DMM) is a water service delivery model, whereby micro-operators financially and operationally manage underserved areas of a piped network. This post-hoc evaluation aimed to assess the impact of DMM on water safety. Kiosk and household stored water in DMM and matched control areas were tested for microbiological quality, showing comparable, substantial post-collection contamination. DMM increased household piped connections, …

  • Effect of Inter-Observer Variation on the Association between Contamination Hazards and the Microbiological Quality of Water Sources

    Open Access•Joseph Okotto-Okotto, Diogo Trajano Gomes da Silva et al.•ARTICLE•International Journal of…•2020

    Sanitary risk inspection protocols are often used to identify contamination hazards at water sources; however, different observers sometimes struggle to record hazards consistently. This study aimed to assess the effect of inter-observer variation in hazard observations on the strength of relationships between observed hazards and the bacterial contamination of water sources, particularly relationships with animal-related hazards. In a longitudin…
