Ghana's farming sector loses billions every dry season to failed crops and stunted yields — not because the land isn't good, but because there's no reliable water. A properly drilled and sited borehole gives you independence from rainfall, rivers, and GWCL supply. It's the single best investment a serious Ghanaian farmer can make.
Why Ghanaian Farmers Need Boreholes
Rain independence
Grow year-round regardless of rainfall. Two or three harvests instead of one.
Reliable water supply
Groundwater doesn't stop during drought. Your crops keep growing when neighbours' fail.
Higher crop value
Dry season vegetables command premium prices. A borehole makes you a year-round supplier.
Solar powered option
Solar borehole pumps run on sunshine — zero electricity cost for irrigation water.
Types of Borehole Irrigation Systems in Ghana
Drip irrigation from borehole
The most water-efficient system — delivers water directly to plant roots through a network of pipes and emitters. A single borehole yielding 500 litres/hour can irrigate 1–2 hectares of vegetables using drip irrigation. Highly recommended for Ghanaian conditions where borehole yield may be limited.
Overhead / sprinkler irrigation from borehole
Sprinkler heads distribute water across the crop canopy. Requires a higher-yield borehole (typically 1,000+ litres/hour) and more energy to pump. Suitable for turf, large vegetable plots, and some field crops.
Gravity-fed irrigation from borehole
Water is pumped from the borehole into an elevated storage tank during the day and gravity-fed to crops. Reduces pump running time and allows solar pumping to supply overnight irrigation needs.
Flood / furrow irrigation from borehole
The simplest but most water-intensive method. Suitable only for very high-yield boreholes. Not recommended where borehole yield is limited.
Borehole Yield — What You Need for Irrigation in Ghana
Before investing in an irrigation system, you must know your borehole's sustainable yield. This is measured in litres per hour (L/hr) and determines what size irrigation system you can run:
- 200–500 L/hr — drip irrigation for 0.5–1.5 hectares of vegetables
- 500–1,000 L/hr — drip or small sprinkler system for 1–3 hectares
- 1,000–3,000 L/hr — medium sprinkler or overhead system for 3–8 hectares
- 3,000+ L/hr — large-scale irrigation, rice paddies, or commercial farming
AquaProbe conducts a pump test after every borehole we drill to measure actual yield before you invest in an irrigation system.
Solar Borehole Pumps for Irrigation in Ghana
Solar-powered borehole pumps are ideal for irrigation in Ghana — they produce maximum output during daylight hours, which aligns naturally with irrigation demand. Key advantages for farmers:
- Zero electricity cost — runs purely on solar energy
- Works in areas without grid power
- Low maintenance compared to diesel alternatives
- Scales with your farm — add more panels as you expand
- Combines with overhead storage tank for flexible irrigation scheduling
Borehole Water Quality for Farming in Ghana
Borehole water quality matters for both crops and irrigation equipment. Key parameters to check before using borehole water for irrigation in Ghana:
- Salinity / EC — high salt content stunts growth and destroys drip emitters
- Iron content — high iron clogs drip irrigation emitters rapidly
- pH — should be 6.5–7.5 for most crops; outside this range affects nutrient uptake
- Bacteria — important for food safety on crops eaten raw
AquaProbe includes a water quality risk assessment with every borehole site survey — so you know before you drill whether your water will be suitable for your crops and irrigation system.
How to Plan a Borehole Irrigation System in Ghana
- Site assessment first — know your expected borehole yield and water quality before any other planning
- Calculate crop water demand — litres per day per crop type and area
- Choose irrigation method — drip, sprinkler, or gravity-fed based on yield and crop
- Size your pump and solar system — based on yield, depth, and daily water demand
- Design storage — overhead tank or reservoir to buffer peak demand
- Drill and install — AquaProbe drills, installs pump and system, and hands you a working water supply

How much water does a borehole produce for irrigation in Ghana?
Borehole yield varies enormously across Ghana depending on geology. Coastal and alluvial areas may yield 500–3,000 L/hr. Hard rock basement areas may yield 100–500 L/hr. A site assessment and pump test give you the actual figure for your location.
Can I use borehole water directly for drip irrigation?
Yes, but have the water tested first — particularly for iron content and salinity, which can clog drip emitters and harm crops. AquaProbe's water quality test identifies any issues before you invest in irrigation equipment.
What is the best pump for irrigation from a borehole in Ghana?
For solar irrigation, the Lorentz PS2 and Grundfos SQFlex series are highly reliable and widely supported in Ghana. For grid-powered irrigation, Pedrollo and Grundfos submersible pumps are the most common. Pump selection depends on borehole depth, yield, and required flow rate.
How many hectares can one borehole irrigate in Ghana?
Using efficient drip irrigation, a borehole yielding 500 L/hr can irrigate approximately 1–2 hectares of vegetables. Using less efficient sprinkler systems, the same yield may only support 0.5–1 hectare. Maximise your yield with the right irrigation method.
