# A swimming pool as an emergency source of water, why not

In an emergency situation where the water supply is closed or interrupted or the water is contaminated, the swimming pool can serve as a source of water for the community. If there is enough water in the pool and its quality is good enough, the water in the pool can be used for drinking, washing or other purposes.

It is important to ensure a controlled release of water so that all supplies are not consumed at once and some people are not left without water. It can be useful to create a system where each member of the community can collect the water in the pool only at certain time intervals.

A possible hygienic risk must also be considered when distributing water. It is important to use clean containers and observe hygiene when carrying and storing water. It should also be ensured that the water has been treated in some way, such as filtered or boiled, before drinking.

It is also important to ensure that the water supply to the pool is shut off to prevent further contamination.

Last but not least, it should be kept in mind that while a swimming pool can be a useful source of water in an emergency, you should not become overly dependent on it. It is important to try to secure enough water from other sources and pay attention to its quality.

If the pool has a capacity of 600,000 liters of water and 5,000 people need 3 liters of water per day, the water in the pool is enough for a certain period of time. The length of this time can be calculated using the following formula:

T = V / (S * d)

where: T is the time for which the water in the pool is sufficient V is the content of the pool in liters S is the number of people who need water d is the daily water consumption per person in liters

**In our case, the time for which the water in the pool is enough is: T = 600,000 l / (5000 * 3 l/day) = 40 days**

If a swimming pool is 25 meters long and 12 meters wide, its content in liters can be calculated using the following formula:

where: V is the volume of the pool in liters d is the length of the pool in meters š is the width of the pool in meters h is the depth of the pool in meters

In our case, the content of the pool is: V = 25 m * 12 m * h

The depth of the pool must be known in order to calculate the contents. If the pool is 2 meters deep, its volume is: V = 25 m * 12 m * 2 m = 600 m^3

1 cubic meter is equal to 1,000 liters, so the volume of the pool is: V = 600 m^3 * 1,000 l/m^3 = 600,000 liters of water.

This pool therefore contains 600,000 liters of water.
