WELLS

We dig holes to pump upunderground water.

WATER TREATMENT

Making water safe for us to drink.

STEP 1: WATER SITS STILL IN A TANK

Heavy things in the water fall to the bottom of the tank.

STEP 2: WATER IS MOVED TO LAYERS OF GRAVEL & SAND

These layers catch the mud and other tiny things.

STEP 3: CHEMICALS ARE ADDED

To kill any harmful things in the water

Chlorine is added to kill the germs and bacteria.
