a) A dug well gives access to a groundwater aquifer and facilitates its abstraction. Dug wells can be entered for cleaning or deepening, and they will rarely be less than 0.8m in diameter. Against the background: i. Identify design parameters impacting the construction of a hand dug well as water source for a rural community. ii. What technology choice is appropriate for a protected well type, where water of adequate quality can be abstracted in sufficient quantity throughout the year from an aquifer within about 50 m from the surface, and where other water systems are less suitable? iii. Critically examine the potential problems associated with hand dug wells.
