How Much Water Do I Need For My Trip?

How much water do I need to bring on my overlanding trip? This question applies to many other situations as well such as hiking, camping, and emergency preparedness. So, in order to answer this question accurately, we need to seek a reputable resource on the topic.

Resources on How Much Water Do I Need

The first place I checked was the Mayo Clinic. The website stated the following, “The Institute of Medicine determined that an adequate intake (AI) for men is roughly about 13 cups (3 liters) of total beverages a day. The AI for women is about 9 cups (2.2 liters) of total beverages a day.”

Age Old Advice

What does that mean for the old saying, “drink eight ounces of water eight times a day…” So, from what I have read recently, it was really just an easy to remember rule. There really isn’t any significant evidence to back up the advice.

Where To Next?

My next stop was the CDC or Centers for Disease Control and Prevention website. I navigated to the Emergency Preparedness section for emergency water supplies. Here, I found great advice for how much water do I need for emergency situations.  The website stated the following, “You need at least 1 gallon of water per person per day…A normally active person needs to drink at least one half gallon of water each day. You will also need water to clean yourself and to cook.”

I wanted to make things very simple for people so I created a very simple calculator. You will see the Overland Trip Water Supply Calculator below, just enter your numbers and the calculator will run automatically.

Other Considerations

Here are some other items to consider when determining how much water is needed for your trip. If you have pets, children, pregnant women, people who are sick or you’re in a hot climate, you will want to consider having additional water available.

If you are limited in your carrying capacity, consider purchasing water filtration devices. These devices allow you to plan stopping points along your trip and replenish the water supply by filtering out the impurities. I have the Katadyn Hiker Pro  which is a fantastic filter!
