In the United Kingdom, where do we get our Water From?

-Surface Water: Lakes, Rivers and Reservoirs really. They will run Low in the Summer Months -Groundwater: Aquifers are Rocks that Trap Water Underground. They are Dominant in the South East [70% of Water is from Aquifers] -Wastewater: Simply treating Water that has been Affected by Human Process - Showering - can be used for a Water Source. Essentially - Recycling Water in a Nutshell which is Important as the UK may Run out of Water to keep Everyone Hydrated.
