Solution

There are various different sources of water out there in the world, and below you will find in depth information on our main water sources.

1. Rivers and streams. : Rivers and streams are a source of fresh (i.e. not salty) water. Collecting water from rivers is still a widespread practice.

2. Lakes. : Lakes are still bodies of (usually fresh) water. They are replenished by the rain and often by rivers and streams, too. Some lakes are natural lakes, forming in valleys in hilly or mountainous regions. Others are man made.

3. The sea. : The sea’s water is salty. Our oceans and seas are, combined, very much the largest water source on earth. Home to many weird and wonderful creatures and ripe for exploration, the sea is essential for biodiversity on earth.

4. Rainwater. : Rainwater falls naturally over all of our planet, except in the very harshest and driest deserts. Rainwater in rural areas is usually safe to drink, though in the cities rainwater can be contaminated by the pollutants found in vehicle and factory fumes rendering it highly acidic.

5. Wells. : Water from wells tends to be very fresh and clean, and they have been a source of water for many centuries. Usually man made, wells are deep shafts dug into the earth until water is found.

6. Reservoirs. : Reservoirs are like artificial lakes created by humans to collect either rain water or river water. The water in a reservoir is typically treated in a water treatment plant until it is safe to drink and then piped off to people’s homes for them to use in the form of tap water.

7. Recycling water. : the water than you drink has been recycled, whether it comes in bottled form or out of the tap? Sewage and tap water than runs down the sink (for instance when you brush your teeth) can be cleaned and sterilized and made ready for people to drink it once more.
