Borehole Dredging & Cleaning

Access to clean, reliable water is a lifeline for Kenyan homes, farms, businesses, and communities. Boreholes, a primary water source amid erratic rainfall and urban water shortages, often suffer from sediment buildup, bacterial growth, and mineral scaling that slash yields by up to 70% over time. Teko Engineering Ltd pioneers Borehole Dredging & Cleaning services in Kenya, deploying cutting-edge techniques to restore full capacity, boost water quality, and extend borehole life by 15-20 years. With over 2,500 projects nationwide since 2018, our owned rigs, in-house hydrogeologists, and NEMA-compliant methods deliver 30-50% cost savings versus competitors.

Why Boreholes Need Dredging and Cleaning

Sediment like sand, silt, and clay accumulates at borehole bases, choking pumps and screens. Biological contaminants—algae, bacteria, and biofilms—thrive in stagnant zones, risking health hazards such as E. coli outbreaks common in 40% of untreated Kenyan boreholes. Mineral scaling from calcium, iron, and manganese further narrows flow paths, dropping yields from 10,000 liters/day to under 2,000. Without intervention, pumps fail prematurely, repair costs soar (KES 50,000-200,000 annually), and water turns turbid or odorous. Regular dredging removes debris via high-pressure airlifting and jetting, while cleaning neutralizes bio-growth with safe chemicals. Teko's protocol revives 92% of boreholes to peak performance on first service.

Teko Engineering's Specialized Process

Our service begins with a hydrogeological site assessment using downhole cameras and yield tests to map depth, sediment layers, and contamination. We issue transparent quotes (starting KES 45,000 for shallow bores) with no hidden fees, scheduling within 48 hours to minimize downtime. Dredging employs submersible pumps and air compressors for surging—dislodging 90% of solids without structural damage—followed by gravel pack restoration in sandy aquifers. Cleaning integrates chemical brushing (eco-friendly acids for scaling) and UV disinfection for pathogens, tailored to Kenya's geology from Rift Valley volcanics to coastal salinity.

Post-treatment, 24-hour test pumping verifies sustained yield (e.g., 5-50 cubic meters/hour), backed by WRMA-approved water quality reports. We restore sites fully, leaving zero environmental footprint per NEMA standards. Nationwide, from Nairobi to ASALs like Turkana, our 4x4 fleets ensure access.

Advanced Equipment and Eco-Safe Methods

Teko invests in owned fleets: DTH rotary rigs for precision dredging, high-pressure jetters (up to 5,000 PSI), and compressor lifts extracting 10 tons of debris per job. Unlike rented gear prone to breakdowns, our calibrated tools handle depths to 300m efficiently. Eco-safe reagents—biodegradable descalers and non-toxic biocides—dissolve iron oxide without harming aquifers, complying with Water Resources Authority (WRA) guidelines. For rehabilitation, we rehab casings with epoxy coatings if corroded, preventing collapse in 15% of aged bores. This tech-driven approach yields 96% client satisfaction, per 1,500+ reviews.

Proven Benefits and Cost Savings

Restored boreholes cut water trucking costs (KES 5,000-20,000/month) and slash pump energy by 40%. Farms regain irrigation capacity, boosting harvests 25-50%; hotels ensure guest safety with pathogen-free supply. A KES 80,000 Teko service pays back in 6-12 months via higher yields. We offer Malipo Pole Pole financing—pay 30% upfront, balance over 6 months at 0% interest for verified clients. Maintenance contracts (KES 15,000/year) include bi-annual checks, extending life beyond competitors' 5-7 years.​

Real Kenyan Success Stories

In Kiambu, farmer Jane Muthoni's 120m borehole yield plummeted to 1,000 liters/day from silt. Teko's dredging restored 15,000 liters, saving KES 120,000/year in trucking—now irrigating 5 acres profitably. Nairobi hotelier David Kim noted scaling halved his supply; our chemical clean-up and UV treatment passed health audits, averting closure. In Machakos, a school borehole clogged with biofilms risked cholera; post-service, safe water serves 800 pupils daily. These cases mirror our 2,500+ drills, with zero disputes and 4.9/5 Google ratings.​

Maintenance Tips for Longevity

• Test water quality annually (KES 5,000 via Teko labs).

• Install filters/screens to block sand ingress.

• Pump regularly to prevent stagnation.

• Schedule dredging every 2-5 years based on usage.

• Monitor yield drops >20% as red flags.

Teko's 24/7 support fixes issues same-day.

Regulatory Compliance and Safety

Kenya mandates WRA abstraction permits for yields >10m³/day; we handle applications seamlessly. NEMA enforces no-discharge policies—our closed-loop systems recycle 95% water. Trained teams wear PPE, using non-hazardous materials safe for groundwater. Post-2025 regulations emphasize pathogen testing; Teko exceeds with quarterly certifications.
