Uses of water

There are four main uses of water from rivers and reservoirs.
Drinking. Water is taken from rivers and reservoirs and pumped to a Water Supply Workswhere it is treated and cleaned so that it is suitable for drinking. The water is then pumped into peoples homes by pipes and can be used for drinking.
Domestic. Water is used for cooking, washing clothes, in baths, for showers, for washing cars, in hose pipes, in dishwashers, for central heating and other activities in the home. The water is taken from taps and, when it has been used, goes down drains. The waste water finds its way to a Waste Water Treatment Works where it is treated before being discharged back into the river.
Car Washing
Industrial. Factories take water directly from rivers and reservoirs. The water is used for many different things such as cooling, driving machinery and to generate electricity in ahydro-electric power station. The used water is sent to the Waste Water Treatment Works.
