Water Management

Water Availability
Geology - Infiltration of water through permeable rock builds up important groundwater supplies. Much of London's water comes from the chalk underlying the city.
Climate - Regions with high rainfall usually have surplus water. Those with drier climates have less water available.
Over-abstraction - Pumping water out of the ground faster than it can be replaced by rainfall. This can cause wells to dry up, sinking water tables and higher pumping costs. Lower water tables mean that rivers are not fed by springs in the dry season.
Pollution - Increasing amounts of waste and growing use of chemicals in farming have led to higher levels of pollution. In some LIC's and NEE's water sources are often used as open sewers leading to waterborne diseases.
Limited Infrastructure - Poorer countries may lack the infrastructure for transporting water to areas of need.
