Drinking water

• Drinking water or potable water is water safe enough to be consumed by humans or used with low risk of immediate or long term harm. In most developed countries, the water supplied to households, commerce and industry meets drinking water standards, even though only a very small proportion is actually consumed or used in food preparation. Typical uses (for other than potable purposes) include toilet flushing, washing, and landscape irrigation.

Freshwaters

• Freshwaters represent only about 3% of all water resources on Earth, and their size is estimated to be approx. 35 million m³. The second largest source is groundwater, which accumulate approx. 29.6% of the resources, and the river, sweet lakes and shallow groundwater accounts for only 0.4% of the total volume of freshwater.

Glaciers

• Interestingly, the largest cluster in the form of glaciers and snow cover on Antarctica. Scientists estimate that there are close to 61% of all the freshwater on the planet, and the remaining glaciers and snows in the world gather 9% water.

Groundwater

• The second largest source is groundwater, which accumulate approx. 29.6% of the resources, and the river, sweet lakes and shallow groundwater accounts for only 0.4% of the total volume of freshwater.

Water shortage

• Most countries in the world suffer from water shortage, only a few have known. surplus. This is an example. Norway, which is due to the relatively small population and the climate is cool temperate waters in abundance.

Water in Africa

• The worst situation is in Africa and some Asian countries. Poland on the background does not come out well - is one of the poorest countries in Europe in the water, and its use is growing. On average, in Europe on one man's fall 5100 m³ per year of life-giving fluid, while in Poland only 1,700 cubic meters.

What to do to save water?
