“Imagine the drip of it, the small splash, echo in a tin mug, the voice of a kindly god”
onomatopoeia engaged senses of the water splashing - how valuable it is - encourages reader to emphasise
monosyllabes emphasise severe dehydration
sibilance of “small splash” elongates the monosyllables - long wait for water
metaphor of “voice of a kindly god” - very little water compared to this - emphasises scarcity of water - seen as sacred and not taken for granted
