Learning Objectives

After completing this module, participants will be able to:

• select suitable well types for different hydrogeological conditions, considering aquifer characteristics, depth, and expected yield
• distinguish between and apply different well constructions, including vertical filter wells, horizontal filter wells, and dug wells, based on technical and environmental requirements
• select an appropriate pumping technology (submersible pumps, centrifugal pumps, multistage pumps, or solar-powered systems) depending on hydraulic conditions and operational needs
• evaluate the yield and performance of a well using pumping tests and basic interpretation of drawdown behaviour
• understand the influence of drawdown cones on well spacing, interference effects, and long-term abstraction planning
• correctly interpret well completion designs, including screen placement and filter gravel selection, and identify common design errors
• implement effective well protection and drinking water protection measures to prevent contamination and maintain water quality over time
• consider energy efficiency, lifecycle costs, and operational reliability when designing and operating groundwater abstraction systems
• link technical design decisions with long-term sustainability and system resilience in drinking water supply planning
