Quick Answer
To effectively harvest water from ice, you'll need about 10-15 pounds (4.5-6.8 kilograms) of ice per person per day, which translates to a 3-4 inch (7.5-10 centimeter) thick ice block covering an area of around 10-15 square feet (0.9-1.4 square meters).
Selecting the Right Ice
When selecting ice for water harvesting, look for clear, transparent ice that’s free from contaminants and impurities. Avoid using ice that’s been contaminated with salt, chemicals, or other substances that can affect the taste and quality of the harvested water. You can also use ice that’s been made from clean, filtered water.
Harvesting Water from Ice
To harvest water from ice, you’ll need to create a hole in the center of the ice block using a sharp tool or a drill. The hole should be large enough to collect the water flowing from the ice. As the ice melts, collect the water in a container or a bag to store it for later use. You can also use a simple filtration system to remove any impurities from the water.
Tips for Effective Water Harvesting
To maximize the amount of water you can harvest from ice, it’s essential to use the right type of ice and to harvest it at the right time. Typically, the best time to harvest water from ice is when the temperature is around freezing, as this will help to slow down the melting process. Additionally, you can use a technique called “ice fishing” to harvest water from ice by creating a series of small holes in the ice and collecting the water that flows through them. This method can be more efficient than harvesting water from a single large hole.
