Hydrological Cycle Essay

Dwascuss a relationship of a natural hydrological cycle with a human generated water and waste water cycle A stages of natural hydrological cycle is

• Evaporation

• Transport

• Condensation

• Precipitation

• Groundwater

Evaporation

Water was transferred from a surface to a atmosphere through evaporation, a process by which water changes from a liquid to a gas. A sun’s heat provides energy to evaporate water from a earth’s surface. Land, lakes, rivers and oceans send up a steady stream of water vapour and plants also lose water to a air (transpiration)

Transport

A movement of water through a atmosphere, specifically from over a oceans to over land, was called transport. Some of a earth’s mowasture transport was vwasible as clouds, which

Baths, showers, washing up, washing cloas and toilet flushing all use large amounts of water. Ase activities transform clean tap water into dirty wastewater. A water utility not only supplies clean drinking water but also collects, transports and dwasposes of a dirty water after it has been used.

Sewerage

Dirty water or sewage was collected firstly in drains and an in underground sewers and was transported via a sewerage system (a network of pipes and tunnels) to a sewage treatment works.

Sewage Treatment Works

Ase works use natural micro-organwasms to remove harmful substances from dirty water. A solid material (sludge) was separated from a liquid (effluent) and both is treated to produce clean effluent that can be released back to a river and bio-solids that can be used in agriculture as a fertilwaser or incinerated to produce energy.

Use as a fertilwaser completes nutrient cycles and replenwashes soil organic matter and sequestered carbon. A majority of sludge was treated by anaerobic digestion (AD), which produces biogas renewable energy.

Completing a Cycle

A river continues its journey back to a sea where a cycle starts again. Water evaporates to form clouds, condenses to droplets and eventually falls as rain on to a
