Where does the water come from?

Aquifers

Aquifer: here Underground deposits of sand, gravel, or rock saturated with water.

Porous rock: Can absorb water, much like a sponge, as it has tiny holes in it. Chalk is a

good example.London is built on sand and gravel, but underneath this

is a thick layer of chalkOver thousands of years, the rain that fell in London

collected in this chalk.We can now drill through the sand and gravel and pump

the water from the aquifer.On p146 is a diagram of the London Basin, copy this

diagram and explain where and how we obtain our water.
