At the heart of effective irrigation lies the problem of lifting or pumping water, and this handbook, newly revised and reformatted, surveys the water-lifting technologies that are available and appropriate for smallholdings.
This publication covers a wide variety of aspects in pump irrigation, ground water, water wells, and costs involved in the use of ground water for irrigation.
Solar power for pumping groundwater has a vast potential for improving the sustainability of water supply schemes. However experience also shows that a lack of knowledge, capacity and expertise to design and implement such schemes is holding back their adoption. This book bridges this gap to equip engineers and technicians with the requisite knowledge for design, implementation and operation of sustainable solar powered water schemes.Solar Pumping for Water Supply 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 that comprise a solar water pumping project, namely: 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.Essential reading for solar technical practitioners at NGOs, UN agencies, government offices and private sector, including Global and Regional Technical advisors and Field engineers wanting to understand and know how to design water systems using solar power. A basic knowledge in the field of water supply is assumed, but no previous knowledge of solar photovoltaic technology is required.Alberto Ibáñez Llario is a Global Solar and Water Advisor with the International Organization for Migration and has 15 years of experience in water systems and solar PV in various locations around the world.Asenath Kiprono is a solar water pumping expert with 12 years' experience in design and implementation of pumping systems in rural Africa, including solar pumping systems in the private, public and humanitarian sectors.
This book has two parts. Part 1 will help you choose the irrigation system that is right for you, and Part 2 will help you select, operate and maintain your pumping equipment. Part 1 If you are installing or upgrading an irrigation system you will probably be seeking to increase production, decrease the amount of water used or reduce labour required. Part one of this book is about selecting the irrigation system that is best for your enterprise. It is an overview of: · the most widely used irrigation methods in NSW · the capabilities and limitations of the most widely used irrigation methods in NSW · the major issues to consider when selecting an irrigation system · the basic financial analysis you can use to determine the viability of a system you are considering. Part 2 You can save money by increasing productivity and efficiency of your irrigation system if you can improve the performance of the pump. This section about the features of common irrigation pumps helps you to select, operate and maintain your pumping equipment. It contains information on pump types, duty, curves and selection. It contains an explanation of: · the common types of pumps for irrigation systems · pumping head components: static head; suction head; velocity head; friction loss · manufacturers’ pump curves · maintenance and troubleshooting procedures for pumps. This publication was produced by Education Delivery, Tocal College. It supports the following competencies from National Training Package AHC10 Agriculture, Horticulture, Conservation and Land Management: AHCIRG306A - Troubleshoot irrigation systems, AHCIRG402A – Determine hydraulic parameters for an irrigation system, AHCIRG410A - Select and manage pumping systems for irrigation
Photovoltaic Water Pumping Systems: Concept, Design and Methods of Optimization looks at the potential of effectively designed PVPS and how they can be commercially efficient and economically competitive to grid connected or diesel generator (DG) based pumping systems. The low energy conversion efficiency of PV modules, nonlinearity of PV module/array I-V characteristics and the unique maximum power operation point are major challenges of this technology, this book provides readers with design and optimization methods, codes and critical analysis of the recent developments in PV pumping systems. Focusing on system feasibility and suitable applications with design procedures, this reference presents a critical analysis of PVPS field performance, modeling and control strategies using artificial intelligence techniques. A suitable text for researchers, engineers and graduate students who are working in the field of photovoltaics and pumping and systems. - Uses open source Matlab codes for PV pumping system optimization - Provides global cases studies and design examples for comparison - Includes a data source sheet for proposed systems for successful implementation methods
