Generate Your Own Water Supply: Methods and Techniques

Generate Your Own Water Supply


When it comes to preparing for emergencies or surviving in the wild, having access to clean water is absolutely essential. Our bodies can survive for weeks without food, but only a few days without water. That’s why it’s crucial to have a reliable and sustainable water source. One way to achieve this is by generating your own water supply. In this article, we will explore various methods and techniques to help you generate clean water when you need it the most.

Catch Rainwater

One of the simplest and most effective ways to generate your own water supply is by collecting rainwater. All you need is a collection system and a storage container. Here’s how you can set it up:

1. Install a rain barrel or a collection tank underneath your downspout.
2. Make sure your collection system is clean and free from debris.
3. Use a filter or mesh screen to prevent leaves and insects from entering the barrel.
4. Regularly check and clean your collection system to maintain its effectiveness.

Rainwater is generally safe to drink, but it’s always a good idea to purify it before consumption. You can use a water purification tablet or boil the water to kill any potential bacteria or parasites.

Harvest Dew

In arid or desert environments where rainwater may be scarce, harvesting dew can be a lifesaver. Dew forms when the temperature cools down during the night, causing moisture in the air to condense on surfaces. Here’s how you can collect dew:

1. Place a clean and flat surface, such as a plastic sheet or a large piece of fabric, on the ground or on vegetation.
2. Make sure the surface is angled so that the dew can flow into a collection container.
3. Leave it overnight to allow the dew to accumulate.
4. In the morning, carefully collect the dew from the container and transfer it to a clean storage vessel.

Although dew is relatively clean, it’s still recommended to purify it before drinking. Boiling or using water purification tablets will help ensure its safety.

Utilize Natural Springs

Natural springs are excellent sources of clean and fresh water. They occur when groundwater seeps to the surface, providing a continuous flow of water. If you find yourself near a natural spring, here are some tips to make the most of it:

1. Locate the source of the spring and observe how the water flows.
2. Use a clean container to collect the water directly from the source.
3. If the spring has multiple outlets, choose the cleanest-looking one.
4. Ensure that the water is clear and free from any signs of contamination.

While natural springs are generally safe to drink from, it’s still a good idea to purify the water to remove any potential pathogens. Boiling is the most reliable method, but you can also use a water filter or purification tablets.


If you find yourself stranded on a deserted island or in a coastal area without access to freshwater, desalination can be a game-changer. Desalination is the process of removing salt and minerals from saltwater to make it suitable for drinking. Here are a couple of methods you can use for desalination:

1. Solar Desalination: This method utilizes the sun’s heat to evaporate the saltwater, leaving the salt and impurities behind. The water vapor then condenses and can be collected. To set up a solar desalination system, you will need a container with a lid, a tube, and a collection container.
2. Distillation: Distillation involves heating the saltwater, capturing the steam, and condensing it back into liquid form. This process separates the salt and pollutants from the water. You can use a pot and a heat source to create a makeshift distillation system.

Desalination requires time and energy, and it’s not the most efficient method for generating water. However, in extreme situations where no other freshwater sources are available, it can be a lifesaving technique.

My 2 Cents

Having a reliable and sustainable water supply is crucial for survival in any emergency situation. By generating your own water supply, you can ensure that you have access to clean water when it’s needed the most. Whether it’s collecting rainwater, harvesting dew, utilizing natural springs, or even desalinating saltwater, there are various methods to generate your own water supply. Remember to always purify the water before drinking to eliminate any potential contaminants. Stay prepared and stay hydrated!
