Drilling a borehole in Ghana is the most reliable way to secure an independent water supply. Done correctly — with a proper site survey and a licensed contractor — a well-sited borehole produces clean water for 20+ years. Done without a survey, it's one of the most expensive mistakes you can make. This guide covers everything before you spend a cedi.

Quick figures: A complete domestic borehole costs GH₵12,000–GH₵28,000 depending on depth and location. A professional site assessment costs from GH₵1,000 and prevents failed holes. AquaProbe's 94% first-drill success rate comes from always surveying first.

How Borehole Drilling Works

A licensed drilling rig advances a drill bit through soil and rock until it reaches a productive aquifer. The borehole is lined with PVC casing, developed (flushed), yield-tested and fitted with a submersible pump. The whole process — from rig arrival to water-on-tap — typically takes 2–5 days on site.

Ghana's Geology and Borehole Depth

🌊 Coastal Sedimentary

Greater Accra, parts of Central Region. Depth: 30–50m. Saline intrusion risk near coast.

⛏️ Birimian Province

Ashanti, Eastern, Western. Depth: 40–65m. 91% success when correctly sited.

🏜️ Voltaian Basin

Northern, Bono East, Oti. Depth: 25–45m. Fluoride risk in some areas.

🪨 Basement Complex

Upper East, Upper West. Depth: 15–40m. Yield varies 0.3–36.4 m³/h — siting is critical.

Types of Borehole in Ghana

  • Domestic — for homes and compounds. 40–60m, submersible pump.
  • Commercial — high-yield for hotels, offices and factories.
  • Agricultural/Irrigation — sized for irrigation demand, often solar-powered.
  • Solar — off-grid system. Zero electricity bills. See solar borehole guide.
  • Community/NGO — hand pump or motorised for schools and clinics.

WRC Licensing — Why It Matters

Under Act 522 (1996) and L.I. 1827 (2006), groundwater in Ghana is vested in the state. Drilling without a WRC Drilling Licence is illegal. Verify any contractor on the WRC Drilling Licence Register before paying a deposit. AquaProbe is fully licensed and provides a completion certificate with every borehole.
