Solar power for pumping groundwater has a vast potential for improving the sustainability of water supply schemes. However, a lack of capacity and expertise to design and implement such schemes is holding back their adoption. This book bridges the gap to equip engineers and technicians with the knowledge for design, implementation and operation of sustainable solar powered water schemes.

Solar Water Pumping for Sustainability is a state of the art review of solar water pumping technology combined with practical insights, lessons and best practices drawn from experience. It takes the reader step by step through the different phases: assessment, design, purchase of equipment, installation, operation and management. The book also covers the economics of using solar pumping technology, especially when compared to diesel generators and hand pumps. Finally, the social aspects are included, specifically relating to the operation and management of solar pumping systems and the role that beneficiaries, implementers, government and the private sector might play to ensure long-lasting water supply. The book provides links and references to tools, documents and videos to accompany the content of the different chapters.

The book is essential reading for solar technical practitioners at NGOs, UN agencies, government offices and private sector, including Global and Regional Technical advisors and Field engineers.
