→‎Other considerations

* The top of the gallery should be ideally 1.5 metres minimum from the riverbed surface. This is so that:

#There is at least a minimum of infiltration that occurs from surface water during the wet season when the river is flooded.

#That there There is less chance that the well shaft and pipework will be washed away in a flood event. Sand becomes mobile to a certain depth which differs for different rivers but has been recorded to be normally between 0.66 and 2 metres in seasonal riverbeds.

* Graded gravel needs to be placed under and over the pipe to minimize clogging with sediments.
