This study explores the implications of monthly flat fee contributions and volumetric (pay-as-you-fetch) payments for water use and revenue generation in rural Mali. Analyzing 4413 months of data across 177 handpumps, the research finds that switching from volumetric payments to monthly flat fees more than triples monthly revenue per waterpoint. While flat fees cover a larger share of operational costs, a subsidy gap remains. Flat fees also double daily water use, with a 1°C temperature increase linked to an extra 180 liters of daily water use per handpump. The study discusses the role of professional service delivery models in supporting reliable drinking water services.
