Poor well water quality? It might be due to overlooking this point during drilling rig selection.

Okay, poor well water quality is often caused by neglecting this point when selecting a drilling rig: the compatibility of the drilling technology with the geological formation.

The key is that your drilling rig must be able to complete the core process of "running the filter pipe and filling gravel" to form a natural filter.

Drilling in sandy soil:

Incorrect selection: Using a auger rig. This will agitate the well walls, causing permanent sand inflow and turbidity.

Correct selection: Using a rotary drill rig. It can drill a regular hole, smoothly run the filter pipe and fill gravel, effectively blocking fine sand and ensuring clear water.

Drilling in hard rock formations:

Incorrect selection: Using an inefficient percussion drill.

Correct selection: Using a down-the-hole hammer drill rig. It can efficiently break rock and blow away rock cuttings, allowing for smoother water flow and fewer impurities.

Conclusion: Before drilling a well, it is essential to confirm the type of drilling rig the drilling team plans to use and whether it includes "water filter pipe and gravel packing" processes. This is crucial for ensuring clear water quality and a long well lifespan.
