where dose water come from

the five keys

Water is collected from rivers, dams or underground, and pumped through pipes to where it is needed

Raw water from rivers is stored here to allow solid particles to settle to the bottom

Special chemicals (called alum) are added to help impurities sink to the bottom and be removed

This process makes impurities settle to the bottom so that they can be removed

The water is filtered through different filters (eg: sand filter) to clean the water
