2.2 - Water supply and control in the UK
1 Supply and Demand
1.1 Most precipitation falls on the uplands (Western England + Scotland)
1.2 Heaviest demand lies in the heavily industrialised and urban regions of the low lands (Eastern England + SE England)
2 Shortage management
2.1 Water Authorities Act (1973) - set up larger regional water authorities
2.1.1 Authorities manage features such as industrial waste disposal, pollution and flood control along with inland fisheries and water recreation
2.1.2 Within these authorities a number of 'water supply only' companies have been formed serving local areas E.g. The Cambridge Water Company
2.2 1989 - New Water Act
2.2.1 Water services placed under 10 new privatised regional water companies
2.2.2 Rivers + groundwater regulatory and conservation functions taken on by National Rivers Authority (NRA) Makes surface and ground water supply
2.3 Water also pumped from upland reservoirs
3 4 major problems for water companies:
3.1 Water pollution
3.2 Concern for conservation
3.3 Growing demand for water
3.4 Stability and flood control
3.5 Causes and solutions to these issues
3.5.1 Water supplies Population increase puts strain on supplies A balanced approach required
3.5.2 Control of flooding Cause - combination of abnormal weather and increased human activity in areas at risk Engineering - limited due to capital - can only reduce flooding risks to an extent Better land management and planning controls Area near North Sea worse affected Low lying land is sinking Sea defences help Thames Barrier - built 1983 - cost £730 million Still liable to flooding every 50 yrs Est £3.5 billion damage without it!
4 How does human activity affect hydrological cycle?
4.1 Building dams - interrupts and modifies surface water flow
4.2 Using water for irrigation
4.2.1 Lowering the water table through over-abstraction of water
4.3 Domestic and industrial use
4.3.1 Pollution of water
4.4 Modifying vegetation affects run-off transpiration rates
