• drinking water (1.5 liters pd)
• water in food (0.9 liters pd)
• water produced during
the metabolism of food (0.6 liters pd)

Water disposal:

• respiration (0.5 liters per day)
• sweating and transpiration: 0.9 liters pd (more in hot weather)
• urine (1.5 litres pd)
• feces (0.1 litres pd)

Water use:

• Saliva: about one liter pd
• Gastric juice: between 2 and 2.5 liters pd
• Bile: 0.5 liters pd
• Pancreatic juice: 0.7 liters pd
• Intestinal secretion: about three liters pd
• Blood contains between three and four litres of water.

 Water Tips 

• Instead of running the tap to get cold water, keep a bottle of drinking water in the refrigerator. It saves time and water.

• While brushing your teeth, fill a glass to rinse your mouth. Don't leave the tap running.

• Baths use less water than a typical shower. Soaking in a partially filled tub will use less water than a short shower.

• Showers use 11 to 20 litres per minute.

• Water makes up about 75% of the brain and 83% of blood; the total amount of water in the body of an average adult is
37 litres.

• Almost 80% of the earth's surface is covered in water. Of this, 97% is salt water, 2% is glacial ice. That leaves less than 1% as fresh water for us to use.

• An average adult drinks about 1.5 litres of water each day. This includes water used in hot and cold drinks.

• In most cities and towns, drinking water coming from the tap is treated, so as not to spread sickness and disease, such as cholera and typhoid, caused by bacteria, viruses or parasites found naturally in the water.

• Don't use water from the hot water tap for drinking or cooking.

or river.
