Scaling Blueprints of Water Supply Business Models
The Scaling Blueprints of Water Supply Business Models publication compiles over a decade of experience supporting impact-oriented water enterprises. It provides practical guidance on five proven business models: Household Water Filters, Water Kiosks, Mini Grids, Hand Pump Maintenance, and Rural Utilities. Each chapter outlines key milestones, financing needs, and performance benchmarks that help entrepreneurs, funders, and support organisations scale viable water supply solutions.
To make these insights more accessible and actionable, Cewas is hosting a series of short webinars—each focused on one business model featured in the publication. Every session offers a concise presentation of findings, reflections from the field, and an open exchange with participants.
