need drinking water from underwater river

everywhere is water

but not all water clean enough for drinking

and waste

all waste mix with soil for planting Minsta

but not all waste can collect successfuly

even walking can make mixture of soil

water around village cannot use for drinking

drinking water come from head of underwater river not so far from village

and transfer by waterway made from Minsta

use terbine of transfer water from river to waterway

waterway past most house and still constract for everyone

if need for drinking water

get glass to nearby waterway

move 1 section of waterway out and wait for water

don't forgot to return section for keep waterway flow to lasted house
