Borehole Rehabilitation & Upgrading
Restoring dysfunctional or silted boreholes, flushing, casing repairs, and upgrading traditional hand-dug wells to secure long-term community access.
Borehole Rehabilitation & Upgrading
Many existing water sources across rural and urban settings suffer from declining yields, mechanical failures, siltation, or casing corrosion. At Biyosahan HydroTech Solutions, we specialize in the comprehensive diagnosis, cleaning, and technical rehabilitation of underperforming or abandoned water supply systems.
By breathing new life into dysfunctional boreholes and upgrading traditional hand-dug wells with modern sanitary protections and pumping systems, we restore reliable, safe water access while significantly reducing capital costs compared to drilling new wells.
Scope of services
- Downhole Video Inspection: High-resolution optical camera logging to visually inspect casing damage, screen clogging, and structural integrity before intervention.
- Mechanical & Chemical Well Flushing: High-pressure air-lifting, surging, and chemical treatments to remove encrustation, bio-fouling, and accumulated silt from well screens.
- Casing Repair & Liner Insertion: Remediation of damaged or collapsed borehole sections to prevent sand entry and structural failure.
- Traditional Well Upgrading: Transforming open, unprotected hand-dug wells into sealed systems equipped with sanitary aprons, proper drainage, and modern extraction mechanisms.
- Pumping System Optimization: Upgrading or replacing outdated pumps with appropriately sized solar or motorized pumping systems matched to the rehabilitated well's safe yield.
