Quick Answer
A shallow well should be installed at a depth of 50-100 feet, depending on the soil type and water table depth. This depth allows for efficient pumping and reduces the risk of collapse. A well installed at this depth typically yields 5-10 gallons per minute.
Water Table and Depth Considerations
When installing a shallow well, it’s essential to consider the local water table and soil conditions. A well installed too shallow may not yield sufficient water, while one that’s too deep may be more expensive to drill and pump. In general, a well installed at a depth of 50-100 feet is suitable for most residential applications. This depth allows for efficient pumping and reduces the risk of collapse.
Soil Type and Well Depth
The type of soil and rock formations in your area will also impact the optimal well depth. For example, in areas with dense rock or hardpan, a shallower well may be necessary to avoid drilling through unproductive strata. In contrast, areas with loose or sandy soils may allow for deeper wells. It’s essential to consult with a professional driller to determine the best well depth for your specific site.
Pump Selection and Yield
Once the well is installed, selecting the right pump is crucial to maximize water yield and efficiency. A submersible pump is often the best choice for shallow wells, as it can be installed directly in the well and provides high flow rates. For example, a 2-inch submersible pump can yield up to 15 gallons per minute, while a 1.5-inch pump may yield around 10 gallons per minute. By selecting the right pump for your well and site conditions, you can ensure efficient and reliable water supply.
