At Radha Krishna Borewells, we utilize a systematic approach to repair collapsed borewells and restore optimal water flow. Here’s an elaboration of each step in the process:

1. Initial Assessment

Objective: To thoroughly inspect the borewell and understand the cause and extent of the collapse.
Process:
Our expert team conducts an in-depth inspection of the collapsed borewell, using advanced tools such as borewell cameras, sensors, and other diagnostic equipment. This step is crucial to determine the nature of the collapse, whether it is caused by shifting soil, casing failure, debris accumulation, or groundwater depletion. The assessment helps identify the exact location and severity of the problem, allowing us to design the most suitable repair strategy.
Outcome: A clear understanding of the underlying issues affecting the borewell, enabling precise planning for cleaning, repairs, and reinforcement.

2. Cleaning and Flushing

Objective: To remove all blockages and clear the borewell shaft of debris, silt, and sand.
Process:
Once the assessment is complete, we proceed with the cleaning and flushing of the borewell. Using high-pressure water jets, we flush out accumulated silt, sand, soil, and any other debris that may have entered the borewell as a result of the collapse. In some cases, air compression or mechanical cleaning tools may also be used to ensure the borehole is entirely clear of blockages.
Why It’s Important: This step is critical because the buildup of debris or sand not only blocks water flow but can also further destabilize the borewell walls. Flushing ensures a clean borewell shaft, providing better conditions for structural repair and improving water flow.

3. Casing Repair or Replacement

Objective: To restore the structural integrity of the borewell by addressing damaged or failed casing.
Process:
During the inspection, we check the condition of the borewell casing—the pipe that lines the inside of the borehole and prevents it from caving in. If the casing is found to be cracked, corroded, or collapsed, it must be repaired or replaced. We use high-quality casing materials such as PVC or steel, depending on the specific requirements of the borewell. The new or repaired casing is carefully installed to ensure that it covers the entire vulnerable section of the borewell, providing robust support and preventing further collapses.
Why It’s Critical: The casing serves as the main support structure for the borewell walls. A weak or damaged casing is a primary cause of borewell collapse, so ensuring that it is properly repaired is essential to long-term stability.

4. Reinforcement of Borehole

Objective: To strengthen the borewell structure and prevent future collapses.
Process:
After cleaning and casing repair, we take steps to reinforce the borehole itself. This may involve using grouting techniques where a cement-based mixture or other advanced materials are injected around the casing to fill any voids and strengthen the surrounding soil. In some cases, reinforcement rings or liners may be used to provide additional support to weakened areas of the borehole.
Why It’s Effective: By reinforcing the borehole walls, we ensure that the well is more resistant to future collapses caused by shifting soil or groundwater level fluctuations. This helps extend the life of the borewell, ensuring reliable and stable operation over time.

5. Final Water Flow Test

Objective: To confirm that the borewell is fully operational and capable of delivering an adequate water supply.
Process:
After completing all repairs, we conduct a final water flow test. This involves using pumps to measure the yield and flow rate of water extracted from the borewell under different pressures. The test ensures that the borewell is functioning optimally and that the water flow has been restored to its previous levels or improved.
Outcome: If the water flow and yield meet the required standards, we can confidently conclude that the borewell has been fully restored to efficient working condition. Any discrepancies found during the test will be addressed through further adjustments or cleaning if needed.

Summary:

At Radha Krishna Borewells, we follow this systematic approach to ensure collapsed borewells are not only repaired but also reinforced for long-term stability and performance. By addressing the root causes of collapse and restoring structural integrity, we ensure that the borewell continues to deliver a consistent water supply for years to come.
