Quick Answer
You may not need a pump for long-term water storage, but it depends on the storage method and your access to the water.
Choosing the Right Storage Method
When storing water long-term, it’s essential to consider the storage method. A tank with a built-in pump or a bladder tank with a submersible pump can be convenient, but they also increase the risk of mechanical failure. A gravity-fed tank or a bucket with a siphon hose is a simpler and more reliable option.
Accessing the Water
If you store water in a gravity-fed tank or a bucket, you may not need a pump to access it. However, if the storage container is elevated or inaccessible, a pump or a siphon hose can help. For example, a 55-gallon drum can be placed on a pallet and lifted with a forklift or a crane, eliminating the need for a pump.
Water Pressure and Flow Rate
When using a pump to access long-term water storage, consider the water pressure and flow rate. A submersible pump can provide a flow rate of up to 4 gallons per minute (gpm), while a diaphragm pump can provide up to 10 gpm. The size and type of pump you need will depend on your specific storage setup and usage requirements.
