I live on a farm. The water we drink comes from the sky lands on the roof and goes into the tank. The water from school comes a bit from the sky and a bit from town. People in the city buy water and get it delivered and also from a water catchment.

Issues with drinking water are that there may be lots of chlorine in the water you get from town. That you may have a drought. You may have flaking paint on the roof of your house and it may go into the tank. One issue at school we had was a dead animal in the tank and we all got sick.

People access drinking water by the tap, shower, river, lake, dam. At school we get our water from the tap and a drinking fountain. Animals access there water from the trough the water is borel water. Sometimes they can also come from a dam or lake.
