To check the static water level in an existing well, you will need a measuring tape or a water level meter. The static water level is the distance from the ground surface to the water in the well when the pump is not operating. This measurement is crucial for understanding the well's capacity and ensuring it meets your water needs.
Why Measure the Static Water Level?
Knowing the static water level helps determine the health and sustainability of your well. It can indicate changes in the aquifer, help in diagnosing well problems, and assist in planning for future water needs. Regularly measuring the static water level can also alert you to potential issues before they become serious.
Tools Needed
- Measuring Tape: A simple, long measuring tape can be used if it is weighted at the end to ensure it reaches the water level.
- Water Level Meter: This device is specifically designed for measuring water levels and provides more accuracy. It uses a probe and a reel with a marked tape.
- Chalk or Marker: To mark the point on the tape where it touches the water.
Steps to Measure the Static Water Level
1. Prepare the Well
Ensure the well is not in operation for at least an hour before measuring to allow the water level to stabilize. Remove the well cap carefully to access the inside of the well casing.
2. Use the Measuring Tape
Lower the weighted measuring tape into the well until you hear or feel it touch the water. If using a water level meter, lower the probe until the device signals contact with water. Mark the tape at the top of the well casing where it meets the ground surface.
3. Record the Measurement
Carefully retrieve the tape or probe, and measure the length from the marked point to the end of the tape or probe. This distance is your static water level. Record this measurement for future reference and comparison.
Interpreting the Results
A stable static water level over time indicates a healthy well. However, significant changes might suggest issues such as over-pumping, seasonal variations, or aquifer depletion. If you notice drastic changes, consider consulting a well professional for advice.
When to Measure
It's advisable to measure the static water level at least once a year, or more frequently if you notice changes in water quality or quantity. After periods of drought or heavy rain, additional measurements can provide valuable data on your well's performance.
Additional Considerations
Before purchasing rural property or if you're new to well ownership, researching the well's history and previous static water levels can provide insights into its reliability. Understanding the well's yield and depth, in conjunction with static water levels, gives a comprehensive view of water availability.
