8 Steps to Calculate How Much Water You Need in Storage to Achieve Water Security in a Drought

Calculating how much water you need in storage to achieve water security during a drought is a crucial step in disaster preparedness.

Water is an essential resource for life, and its scarcity during droughts can pose significant challenges to communities and individuals alike. To ensure water security in times of drought, having an adequate water storage system in place is crucial. But how much water do you actually need in storage to achieve this level of security? In this blog post, we will explore the various factors and calculations required to determine the right amount of water you should store to withstand a drought effectively.

Understanding Your Water Needs

Before delving into the calculations, it’s essential to understand your specific water needs during a drought. These needs can vary significantly depending on factors like the size of your household, climate, access to alternative water sources, and the duration of the drought. Here are some key considerations:

Household Size: The number of people in your household directly impacts your daily water consumption. Each person typically requires between 50 to 100 gallons of water per day for drinking, cooking, sanitation, and other basic needs.

Climate and Local Conditions: Different regions experience droughts of varying intensity and duration. Understanding your local climate and drought patterns will help you anticipate how long a drought may last.

Alternative Water Sources: Consider whether you have access to alternative water sources such as wells, rainwater harvesting systems, or nearby water bodies. These sources can supplement your stored water during a drought.

Duration of Drought: Assess how long droughts typically last in your area. While it’s impossible to predict precisely, historical data can provide some insights.

Calculating Your Water Storage Needs

Now, let’s get into the calculations to determine how much water you should store for water security during a drought.

Step 1: Determine Your Daily Water Needs

Start by calculating your daily water needs based on the number of people in your household. As mentioned earlier, each person generally requires between 50 to 100 gallons per day. Use a conservative estimate to ensure you have enough water.

Step 2: Assess the Duration of Drought

Estimate how long the drought might last based on historical data or local drought predictions. Be prepared for the worst-case scenario.

Step 3: Calculate Your Total Water Needs

Multiply your daily water needs by the estimated duration of the drought. This will give you the total amount of water required to sustain your household during the drought. Here’s the formula:

Total Water Needs = Daily Water Needs (per person) × Number of People × Duration of Drought (in days)

Step 4: Account for Additional Uses

Consider any additional water needs beyond basic consumption, such as watering gardens or livestock, which can be significant during droughts. Add this to your total water needs.

Step 5: Adjust for Alternative Water Sources

If you have access to alternative water sources like rainwater harvesting or a well, subtract the estimated water you can collect from these sources during the drought. This will reduce your reliance on stored water.

Step 6: Determine Storage Capacity

Now that you have your total water needs, you can calculate the storage capacity required. Most water storage containers come in gallons or liters. Convert your total water needs to the appropriate units if necessary.

Step 7: Select Suitable Storage Containers

Choose the right type and number of storage containers based on your storage capacity requirements. Keep in mind that it’s often more practical to have multiple smaller containers rather than one large tank for flexibility and accessibility.

Step 8: Plan for Water Treatment

Don’t forget to plan for water treatment and purification systems to ensure the stored water remains safe to drink throughout the drought.

Factors Affecting Water Storage

To make your water storage plan as effective as possible, consider the following factors:

Container Material: Select containers made of food-grade materials like polyethylene or stainless steel to ensure water quality.

Storage Location: Store water in a cool, dark place to prevent bacterial growth and evaporation.

Rotation: Regularly rotate your stored water to keep it fresh and prevent stagnation.

Water Treatment: Invest in water treatment methods such as filtration, chlorination, or UV sterilization to ensure the stored water remains potable.

Emergency Supplies: Besides water, stock up on emergency supplies like non-perishable food, first-aid kits, and flashlights to ensure your overall preparedness during a drought.

Conclusion

Calculating how much water you need in storage to achieve water security during a drought is a crucial step in disaster preparedness. By understanding your specific needs, considering local conditions, and performing the necessary calculations, you can ensure that you and your household have access to a reliable source of water even in the most challenging times. Remember that water storage is just one part of a comprehensive drought preparedness plan, so stay informed, stay ready, and stay safe.
