The Water Treatment Plant (idk how to do this lol)

basically say the next stage
Item Next
water comes into the system that filters out large solids (plastic bottles, litter, plants, fish etc)...
water is pumped into a large holding tank where a chemical is added to make small solids clump together and settle to the bottomwater is passed through a special membrane filter to take out any tiny solids
water is passed through a special membrane filter to take out any tiny solidschlorine is added to skill any microorganisms that have not been removed by filtering alone
chlorine is added to skill any microorganisms that have not been removed by filtering alonethe drinkable water is pumped out to storage sites such as water towers and underground reservoirs
the drinkable water is pumped out to storage sites such as water towers and underground reservoirslast
