Nyanza Region's Leading Borehole Drilling Service Provider

By Teko Engineering Ltd

Access to clean, reliable water is the cornerstone of healthy communities, productive farms, and thriving businesses. Across the Nyanza region — spanning Kisumu, Siaya, Homa Bay, Migori, Kisii, and Nyamira counties — Teko Engineering Ltd has established itself as the most trusted name in borehole drilling, water engineering, and groundwater development. With a deep understanding of the region's unique hydrogeology and an unwavering commitment to quality, Teko Engineering delivers water solutions that stand the test of time.

Why Nyanza Needs Reliable Borehole Drilling Services

The Nyanza region is home to over six million people, many of whom depend on surface water sources such as Lake Victoria, rivers, and seasonal streams. While the region receives relatively good rainfall compared to Kenya's arid zones, water access remains inconsistent due to pollution of surface sources, seasonal fluctuations, and the growing demands of an expanding population. Municipal water supply systems in towns like Kisumu, Kisii, and Migori are frequently unable to meet demand, leaving households, schools, health facilities, and agribusinesses underserved for weeks at a time.

Groundwater offers a dependable, year-round alternative. The Nyanza region sits atop productive aquifer systems — including weathered basement rock aquifers and alluvial formations along river corridors — that can yield thousands of litres per hour when properly identified and drilled. Teko Engineering Ltd has the expertise, equipment, and field experience to unlock this resource safely, legally, and affordably.

"In Nyanza, groundwater depths typically range between 30 and 120 metres, making the region one of Kenya's most accessible zones for cost-effective borehole drilling. With the right survey and drilling approach, most sites can achieve yields of 1,500 to 5,000 litres per hour."

About Teko Engineering Ltd

Teko Engineering Ltd was founded with a singular mission: to bring world-class water engineering services to the people of Nyanza and the wider Lake Region. Based in Kisumu, the company operates a fleet of modern down-the-hole (DTH) drilling rigs capable of reaching depths of up to 250 metres, making them equipped to handle the full range of geological conditions found across the region — from the soft sedimentary formations near the lake basin to the hard crystalline basement rocks of Kisii and Nyamira highlands.

Over the years, Teko Engineering has successfully completed hundreds of borehole projects for residential clients, county governments, non-governmental organisations, tea factories, fish processing plants, schools, hospitals, and irrigation schemes. Every project is handled by a team of qualified hydrogeologists, drilling engineers, and pump technicians who bring technical precision and local knowledge to every site.

Our Borehole Drilling Process

Teko Engineering follows a rigorous, step-by-step process designed to maximise water yield, ensure structural integrity, and deliver full regulatory compliance.

Hydrogeological Survey and Siting: Every borehole project begins with a thorough geophysical survey using resistivity meters and Vertical Electrical Sounding (VES) techniques. This survey maps subsurface water-bearing formations and identifies the optimal drilling location — dramatically reducing the risk of a low-yield or dry borehole. Teko Engineering never recommends skipping this critical step.

Drilling and Casing: Once the site is confirmed, our rigs are mobilised and drilling commences. We use both rotary and DTH hammer drilling methods, selected based on the specific geology of the site. High-quality uPVC and steel casing is installed to prevent borehole collapse and protect the aquifer from surface contamination. Gravel packing and cement grouting are applied to complete a structurally sound and hygienically safe borehole.

Pump Testing and Yield Analysis: After drilling, every borehole undergoes a comprehensive pump test — including step drawdown and constant rate tests — to determine the safe sustainable yield. This data guides pump selection and ensures the borehole is not over-abstracted, protecting the long-term productivity of the aquifer.

Pump Supply and Installation: Teko Engineering supplies and installs submersible pumps from globally trusted manufacturers, precisely matched to the borehole's depth, yield, and the client's water demand. We also offer solar-powered pumping systems that eliminate dependence on the electricity grid — ideal for rural farms, off-grid schools, and community water points across Nyanza's vast rural landscape.

Water Quality Testing: Before any borehole is commissioned for drinking water use, Teko Engineering conducts full water quality analysis covering physical, chemical, and microbiological parameters, benchmarked against Kenya Bureau of Standards and WHO guidelines. Where treatment is required, we design and install appropriate systems including UV sterilisation, iron removal filters, and chlorination units.

"Solar-powered borehole systems have transformed rural water access in Nyanza. A well-sized solar pump can deliver over 10,000 litres per day with zero fuel costs — making clean water genuinely affordable for even the most remote communities."

Serving All Six Nyanza Counties

Teko Engineering Ltd provides borehole drilling and water engineering services across the entire Nyanza region. In Kisumu County, we serve urban estates, industrial facilities along the Kisumu–Nairobi highway, and lakeside communities. In Siaya County, our teams have drilled for schools, rural homes, and county government water projects in areas with limited municipal coverage. Across Homa Bay and Migori counties, we support smallholder farmers, beach management units, and health centres with reliable groundwater access. In the highland counties of Kisii and Nyamira, where tea farming and densely populated hillside communities create high water demand, our deeper drilling capabilities and knowledge of the basement rock geology ensure successful outcomes.

Regulatory Compliance and WRA Registration

Teko Engineering Ltd is fully registered with the Water Resources Authority (WRA) as a licensed borehole driller under the Water Act 2016. We manage all permit applications, drilling notifications, borehole registration, and abstraction licencing on behalf of our clients — ensuring every project is fully compliant with Kenyan water law from day one. Clients receive a complete documentation package upon project completion, including the driller's log, pump test report, water quality certificate, WRA registration, and GPS coordinates.

"Drilling a borehole without a WRA permit is illegal under Kenya's Water Act 2016 and can result in fines, forced closure, and loss of your investment. Always insist on working with a licensed, WRA-registered driller."
