Quick Answer
A 2-3 gallon per minute (GPM) well production rate is commonly sufficient for a small off-grid property, but this can vary depending on the number of users, water needs, and the well's depth and yield.
Determining Well Production Needs
When it comes to well production, the key is to determine the minimum amount of water needed for your off-grid property. A general rule of thumb is to calculate 50-100 gallons per day for a single person. For a family of four, you’ll need at least 200-400 gallons per day. Based on these estimates, a well producing 2-3 GPM can supply a small household with enough water.
Well Depth and Yield Considerations
The depth and yield of your well will also impact its production rate. Shallow wells (less than 100 feet deep) tend to produce more water than deeper wells. However, deeper wells can still be productive if the aquifer is extensive and the well is drilled correctly. A well with a high yield (more than 5 GPM) may be overkill for a small off-grid property, but it can be beneficial if you anticipate future growth or high water demands.
Choosing the Right Pump
Once you’ve determined your well’s production rate, you can select a suitable pump. Submersible pumps are often the best choice for shallow wells, as they are efficient and easy to maintain. For deeper wells, a jet pump or turbine pump may be more suitable. When selecting a pump, consider factors such as flow rate, head pressure, and power consumption to ensure it meets your well’s needs and your budget.
