This manual presents a comprehensive training design, suggested procedures, and materials for conducting a workshop in the design, construction, operation, maintenance, and repair of hydrams, and in the planning and implementation of hydram projects. Hydrams (hydraulic rams, hydraulic ram pumps, automatic hydraulic ram pumps, rams) are devices that use the force of water falling through a drive pipe to pump water to a height greater than its source, making use of hydraulic principles and requiring no fuel. The manual includes 20 sessions for the design and construction of modified and fabricated pipefitting and cement rams, and complete instructions for a clear PVC demonstration ram. Each session includes learning objectives, recommended time, suggested procedures, the specific tools, materials, and resources required, notes for trainers (which clarify procedures, provide background information, or suggest options), and activities (designed for 15-20 participants with two trainers) which incorporate such learning techniques as demonstrations, problem-solving, skill practice and guided construction, and large and small group discussions. Guidelines for users (including lists of training objectives, pre-workshop tasks, and tools, equipment, and materials needed) are provided in an introductory section. The entire workshop requires ten 8-hour working days. (JN)
