 Comes
from pipes?
 Water comes from a reservoir or water
tower
 Water has been treated and purified
 If the water originated from a river it is
called SURFACE WATER
 If the water has originated from a well
you are using GROUND WATER (well)
Rural Water
– (a water-bearing layer of rock,
sand or gravel)
 Where else can water come from in rural
areas?
