Customer Background
Kiambu County in central Kenya suffers from perennial drought. A local cooperative, Green Valley Water, undertook a government project for rural drinking water supply and agricultural irrigation. The project entailed drilling 50 wells—every 60 meters deep—with a requirement for completion and handover within 30 days. Previously, the client had primarily relied on large truck-mounted drilling rigs; however, these proved difficult to maneuver through narrow village paths and hilly terrain, and incurred high transportation and operational costs. Consequently, the client urgently needed equipment that balanced portability with efficiency. In the third quarter of 2024, the client contacted YG Company seeking a compact water well drilling rig solution suited to rural African operating conditions, explicitly prioritizing “rapid site-to-site mobility” and “low operating costs” as the key selection criteria.
Challenges and Requirements
The client faced four major pain points:
- Large drilling rigs were bulky and required disassembly to enter villages, with one-way transport taking over two days.
- Conventional equipment had high fuel consumption, resulting in per-well operating costs exceeding $800 and a long return-on-investment period.
- Drilling was slow due to complex geological conditions (weathered rock and gravel layers), making it difficult to meet the original project schedule.
- A lack of skilled local operators made training and after-sales support critical constraints.
The client’s specific requirements were: the equipment must be self-propelled (crawler-mounted) or easily disassembled, operable by a two-person team, capable of completing a well within 8 hours, and supported by operation manuals in both Chinese and English along with remote guidance. Based on these needs, the YG team selected the YG-240-30P portable drilling rig, simultaneously addressing the pain points regarding transport, energy consumption, and labor requirements.
Solution
YG recommends the YG-240-30P portable small-scale water well drilling rig, supplied with a comprehensive equipment package:
- Main Unit: Drilling depth of 200m, hole diameter of 150–300mm; dual power options (diesel engine or electric motor).
- Crawler Chassis: Self-propelled mobility; navigates easily across hilly terrain and muddy ground without the need for a trailer.
- Included Tools: BW-160 mud pump, 20 drill rods (φ50), and three sets each of alloy and PDC drill bits.
- Technical Support: Remote video training prior to arrival, bilingual manuals (Chinese/English), real-time Q&A via WhatsApp, and a spare parts kit for wear items.
This solution reduces the equipment investment per well to just 60% of that required for large-scale rigs. By eliminating the need for extra trailers and heavy lifting equipment, it removes major obstacles regarding transport and high costs, resulting in a highly competitive overall price for the water well drilling rig.
Implementation Process
After the equipment was shipped to the Port of Mombasa, YG engineers conducted remote video training for two local operators on equipment handling and maintenance, enabling the client to operate the machinery independently by the very next day. The project utilized a “crawler-based relocation + slurry wall stabilization” method:
- 1.5 to 2 wells were completed daily, with an average of 6–8 hours per well.
- PDC bits were used for gravel layers, while slurry density was increased in weathered rock strata to prevent borehole collapse.
- A four-step acceptance process—drilling, well cleaning, pumping tests, and handover—was followed, with all wells meeting turbidity standards.
By the 25th day, all 50 wells were completed and passed government inspection—finishing five days ahead of schedule. No major malfunctions occurred throughout the process, and only two items from the spare parts kit were utilized; the equipment’s stability earned the client’s approval.
Results and Data
The project delivered impressive results:
- Wells completed: 50 (100% target achievement);
- Total drilling depth: 3,000 meters;
- Time per well: 6–8 hours—approximately 50% faster than traditional drilling rigs;
- Overall cost: 40% lower than renting large-scale equipment; cost per well dropped from $800 to approximately $480;
- Manpower: Operated by just 2 people, saving 60% on operator labor costs;
- Return on investment: Clients recouped their investment within 3 months through irrigation and water supply operations.
The data speaks for itself: with a 50% increase in efficiency and a 40% reduction in costs, the YG-240-30P has been selected as the designated model for the client’s Phase II project.
Customer Testimonial
“The YG-240-30P truly exceeded our expectations! The equipment is lightweight and portable; the crawler tracks allow it to drive straight into the fields, and the operation requires only one or two people. We drilled 10 wells in just seven days, finally providing the villagers with access to clean water.” — James Mwangi, Project Manager at Green Valley Water
Customer Note: The availability of manuals in both Chinese and English, combined with remote guidance via WhatsApp, enabled the local team to get up to speed quickly. Fast after-sales support and a comprehensive stock of spare parts completely dispelled any concerns about the difficulty of maintaining imported equipment. The cooperative has since placed an additional order for two units and plans to introduce the YG small-scale water well drilling rig to drinking water projects in neighboring counties.
Case Summary
The Kenya case study demonstrates that the YG-240-30P small water well drilling rig is perfectly suited for rural drinking water and irrigation projects in Africa, combining portability, high efficiency, and low costs. Compared to traditional large-scale rigs, it reduces expenses across transportation, energy consumption, and labor—delivering a 40% reduction in cost per well and a 50% increase in efficiency—making it the ideal choice for well-drilling projects in developing countries.
