Water: a renewable resource
Water is a basic natural resource needed to maintain human and animal life and to grow food
It is a renewable resource
1. Evaporation – Water transferring from the ground into water vapour in the air.
2. Condensation – Water vapour in the air turning back into a liquid.
3. Cloud – Water droplets are held in the air in the form of clouds.
4. Precipitation – Water that falls to the ground in the form of Hail, Rain, Sleet, or Snow.
5. Run – off – Water running over the ground back to the sea.
Water Cycle song
In groups discuss the various ways in which we use water?
Is water important to us?
Water is a renewable resource but sometimes people abuse this resource.
Can you think of any way in which humans abuse our water.
Businesses can be charged water rates. Some can be metered which means the more water they use the more they pay.
Some toilets, dishwashers and washing machines have been fitted with devices to use water more efficiently.
Some industries recycle water
TV and radio campaignshave urged consumers to conserve water.
Before the water is used it goes through many processes
The water is collected
It is stored in reservoirs
The water is treated to make it safe
The local authorities e.g county councils or city cooperations
Co-operative water schemes – groups of households coming together to provide their own water.
Some houses have a well on their property
Three reservoirs – Leixlip, Vartry reservoir and Poulaphouca reservoir.
Mountaneous region and recieves high
levels of rainfall.
Impermeable rock – does not allow water to pass through
This is ideal for the collection of rainwater.
The river liffey also provides water.
Water treatment plant is in Ballymore Eustace, Co. Kildare.
The treated water is piped to reservoirs and then piped to houses and business.

Irrigation is the artificial watering of the land.
There are 3 main ways of irrigating the land
Sprinklers and canals
Flooding whole areas
Boring wells to use ground water.
Mediterranean Climate – hot dry summers with almost no rain in June, July and August. Temps 30°C
Winters are mild and wet (8°C)
California suffers from drought – long period of time with no rain.
Agricultural land is in the south end of California in the San Joachin Valley. There is a little supply of water.
In the north there is the Sacramento River, where there is a large supply of water.
Plan was to move water from the wetter northern end of the Central Valley Project to the dry southern end.
Dams and reservoirs were built across the Sacramento River.
Canals were built to transfer this water southwards to the San Joachin Valley.
Water is stored during the winter months and used in the summer.
During hot, dry summers water is used to irrigate land.
Generates hydroelectric power which is used to pump water through the canals to the San Joachin Valley
The cities and towns receive a regular supply of water.
The reservoirs behind the dams are used for tourist and leisure activities.
Dam construction and running dams is very expensive
High temps in California which results in high rates of evaporation. The water that is left has a high salt content which can poision crops.
Some farmland was flooded to create the dams. Farmers and their families had to move away.
