1. What is borehole rehabilitation?
Borehole rehabilitation involves the process of restoring a borehole that has reduced water yield or has stopped functioning efficiently. It includes cleaning, repairing, or upgrading the borehole infrastructure to improve water flow and quality.
2. Why is my borehole producing less water than before?
Several factors can cause a borehole to produce less water over time, such as:
- Siltation or clogging of the screen and pipes.
- Aquifer depletion or water table lowering.
- Mechanical failure of pumps or other equipment.
- Corrosion or scaling within the borehole.
3. How do I know if my borehole needs rehabilitation?
Common signs that a borehole requires rehabilitation include:
- Reduced water yield.
- Murky or contaminated water.
- Air coming from the taps instead of water.
- Frequent pump failure.
- Increased power consumption of the pump.
4. What are the common borehole rehabilitation techniques?
- Cleaning: Removing silt, sand, or debris from the borehole using mechanical or chemical methods.
- Repairing or replacing damaged components: Such as pumps, pipes, or screens.
- Rescreening or relining: To prevent collapse or enhance water filtration.
- Redevelopment: Techniques like surging or air-lifting to improve water flow.
- Chemical treatment: For scaling or corrosion inside the borehole.
5. How long does borehole rehabilitation take?
The time taken for rehabilitation depends on the condition of the borehole and the techniques used. It may range from a few days to several weeks for complex cases.
6. How much does borehole rehabilitation cost in Kenya?
The cost varies depending on the scope of work, the depth of the borehole, and the extent of damage. Rehabilitation can be more cost-effective than drilling a new borehole, but it’s advisable to get a detailed assessment and quote from professionals like HydroConnect.
7. Can all boreholes be rehabilitated?
Not all boreholes can be successfully rehabilitated. If the aquifer has dried up or the borehole is too old and structurally compromised, drilling a new borehole may be the only solution.
8. What happens during a borehole inspection?
A borehole camera inspection is typically conducted to assess the condition of the borehole, check for damage, and identify blockages or contamination. This helps determine the necessary rehabilitation steps.
9. What are the benefits of borehole rehabilitation?
- Restores water yield and quality.
- Extends the life of the borehole.
- Avoids the cost of drilling a new borehole.
- Improves efficiency and reduces maintenance costs.
10. How often should a borehole be inspected?
It is recommended to have a borehole inspection every 2 years or sooner if issues arise, such as reduced water flow or changes in water quality.
