Water Well Drilling Services
With two decades of specialized expertise, BushProof is the leading provider of water well drilling services across Madagascar. We leverage state-of-the-art equipment combined with deep knowledge of the landscape and environments to construct high-quality, sustainable water wells.
Our drilling services span a range of techniques that enable us to build water access solutions across many remote areas and difficult terrains using the best-fit approach:
BushProof is operating different compact hydraulic drilling rigs for both DTH-Hammer and rotary drilling. The rigs are usually set up with a centrifugal mud pump (>1,000 litres/min at 6 to 8 bar) or air compressors (350-650 cfm / 12-20 bar). Our rigs enables drilling in all soft and hard rock formations; air / mud rotary drilling (4″-12″); DTH-Hammer (4″-6″1/2), maximum depth 200 m. Allows to build water wells of 75 to 200 mm diameter.
BushProof is also using a semi-manual operated, lightweight and portable rig. Specs: mud rotary drilling in alluvium to soft rock formations; borehole diameter 4″-10″ (100-200 mm), maximum depth 60 m. Allows to build water wells of 75 to 140 mm diameter.
The Madrill technique (MAnual DRILLing) has been developed and tested by BushProof in Madagascar. It integrates the best parts of the EMAS and rota sludge techniques. The material is lightweight, inexpensive, and easy to transport to remote locations. Specs: suitable to drill in all types of soils excluding hard rock formations; 150 mm diameter borehole; 75-125 mm PVC casing and screen; maximum depth of 30 m; suitable to build water well for hand pump abstraction.
Well jetting is a simple, low-cost and very rapid method for well construction in sandy shallow aquifers. BushProof has years of experience in implementing jetting campaigns and has conducted research proving the viability of this method. Specs: suitable to build water wells in sandy aquifers with shallow water table; 63 mm PVC casing and screen; geotextile liner; maximum depth of 10 m; suitable for hand pump abstraction.
