Hydrogeological & Geophysical Investigations

Accurate subsurface characterization is the cornerstone of sustainable groundwater development. At Biyosahan HydroTech Solutions, we combine advanced surface geophysics with rigorous hydrogeological analysis to identify high-yield aquifer zones, evaluate aquifer geometry, and minimize the risk of dry holes. Our integrated approach bridges regional hydrogeological data with precise site-specific investigations, ensuring optimal placement and long-term viability for water supply, agricultural, and industrial borehole projects.

  • Advanced Electrical Resistivity Tomography (ERT) & Vertical Electrical Sounding (VES): High-resolution subsurface profiling to determine lithological variations, depth to water table, and aquifer boundaries.
  • Structural & Geological Mapping: Identification of regional fault lines, fracture zones, and permeable formations that govern groundwater movement.
  • Aquifer Hydraulic Property Estimation: Assessment of expected yields, transmissivity, and storage coefficients based on geophysical and geological correlations
  • Borehole Site Selection & Risk Mitigation Reports: Comprehensive pre-drilling technical reports providing exact GPS coordinates, expected drilling depths, and geological succession logs to eliminate exploratory guesswork.
  • Pumping Test Supervision & Evaluation Guidance: Technical advisory on post-investigation testing to determine safe yield and sustainable extraction rates.

State-of-the-art mud rotary, air rotary, and air percussion drilling techniques capable of reaching deep aquifers (up to 350m+) with optimal casing and gravel packing. Built to withstand arid and semi-arid conditions across the Federal Member States, our drilling operations adhere to rigorous engineering and environmental standards. We ensure structural integrity, high yields, and long-term borehole operational resilience for community water supplies, agricultural irrigation, and commercial projects.

  • Deep Aquifer Rotary Drilling: Advanced mud and air rotary drilling methodologies tailored to penetrate complex consolidated and unconsolidated lithological formations.
  • Casing & Screen Installation: Installation of high-strength PVC or steel casings coupled with precision-slotted screens to maximize water inflow while preventing sand pumping.

  • Sanitary Well Sealing & Headworks: Construction of sanitary concrete surface seals and secure wellheads to prevent surface contamination and protect groundwater quality.
  • Initial Yield Testing & Disinfection: Pre-commissioning test pumping and chlorination to ensure water safety and verify immediate borehole performance.
Borehole Rehabilitation & Upgrading10
Water Risk & Resilience

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.

  • 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.
