If a survivor where to find themselves in a situation where water was scarce they would obviously become dehydrated and the rate of urination would drop, for arguments sake to 500ml<. This leaves a rough figure of 1 Litre or 32 ounces to keep the average human alive whilst resting in a temperate environment.
But there are some basic guidelines: For men, the Institute of Medicine (IOM) recommends a total of 13 cups (about 3 liters) of fluid each day. For women, they suggest 9 cups (a little over 2 liters) of fluid each day. Pregnant women should drink about 10 cups of water daily.
If you lose 1 liter of water per day and drink 1 liter each day, 2 gallons (7.5 liters) of water would keep you well hydrated for 7.5 days. After that you will continue to lose 1 liter of water per day, you'll become progressively dehydrated, but you could survive for the additional 8 days, so 15.5 days in total.
A normally active person needs to drink at least two quarts (half gallon) of water each day. People in hot environments, children, nursing mothers, and ill people will require even more. You will also need water for food preparation and hygiene. Store at least one gallon per person, per day.
Women should have about 2 litres (8 cups) of fluids a day, and men about 2.6 litres (10 cups). Women who are pregnant or breastfeeding need more fluid each day than other women. Dehydration can happen when the body's fluids are low. It can be life threatening, especially to babies, children and the elderly.

As a general rule of thumb, a person can survive without water for about 3 days. However, some factors, such as how much water an individual body needs, and how it uses water, can affect this.
Health authorities typically recommend a person drinks 64 ounces (or half a gallon) of water a day, and therefore a person should drink around 15 gallons per month. This can prove to be a challenge, especially when water is often replaced with soda or other beverages.

Your kidneys can process a maximum of 0.7 to 1 liter of water per hour. If you drink too much, your kidneys can't handle that huge amount of water. This also happens if, for example, you drink 4 liters of water in a short time (without exercising intensively in the meantime).
The fastest time to drink 1 litre of water (hand stand) is 29 seconds, and was achieved by Rishishwar Pariyar (Nepal) in Tulsipur, Nepal, on 13 September 2022. Rishishwar was confident he could achieve this record.

After three to five days of not drinking water, your organs begin to shut down, especially the brain, which could have lethal consequences including fainting, strokes and in extreme cases, even death.
