Questionnaire and Water Quality Data for Post Hoc Evaluation of the Water Safety Impacts of Kisumu’s Delegated Management Model of Water Service Delivery, 2022

This data set comprises a questionnaire survey and results of microbiological water quality testing, which were conducted through a post-hoc impact evaluation study of the delegated management model (DMM) of water service delivery in the city of Kisumu, Kenya. Under DMM, a water utility passes on responsibility to a micro-enterprise or community group for local water service delivery within a low-income neighbourhood. The micro-enterprise or community group takes on the financial and operational management of water infrastructure within this local area. The aim of this study was to evaluate DMM’s impact on water safety among consumers of water sold by kiosks. The data set comprises questionnaires administered to water vendors, both kiosk operators and water hand-cart operators, within DMM areas and matched control areas within Kisumu. These questionnaires cover respondent socio-demographic characteristics, business finances, operation and water prices, water supply interruptions, treatment and storage facilities. Questionnaire interviews were also conducted with households purchasing water from these businesses. These questionnaires also cover socio-demographic and housing characteristics of these households, together with water prices, handling and treatment alongside sanitation, solid waste and hygiene provision. Water samples were taken from kiosks, hand-carts, pipelines, and from household stored water. The data set thus also includes microbiological (e.g. thermotolerant coliform) and chemico-physical parameters (e.g. free residual chlorine) for these water samples.
