Project Overview
The Nkywanga project, funded by ADRA Uganda, was initiated to support two farmer groups in cultivating crops during the dry season. Although the original plan in 2024 envisioned irrigating 10 acres, budgetary limitations scaled the system to 5 acres shared between the two groups.
Greyam Irrigation Technologies was brought in to design and install a solar-powered irrigation solution capable of overcoming the steep elevation between the valley water source and the elevated farm plots.
System Components
- 1500-watt solar-powered pump with a 203m head capacity.
- 550 solar panels for reliable off-grid power generation.
- “Drag hose” manual irrigation system, where hoses are connected to hydrants for flexible distribution.
- 16 hydrants (1-inch each) strategically placed across the two plots.
- 4 fire hoses (1-inch) provided for group irrigation needs.
- Fenced powerhouse with chain-link for security.
- Pump culverts for equipment safety and durability.
Farmer Testimonial
“With the solar system, we can now grow crops even in the dry season. Our groups are working together and the system is secure, reliable, and easy to use.”

Results & Impact
- 5 acres brought under solar-powered irrigation, shared by two farmer groups.
- Reliable off-grid water delivery, overcoming steep terrain challenges.
- Affordable and sustainable energy source, reducing long-term operational costs.
- Enhanced community cooperation, with shared access to hydrants and hoses.
- Secure and durable infrastructure, with fenced powerhouse and sealed pumps.
Key Takeaway
The Nkywanga project demonstrates the practical potential of solar-powered irrigation in rural Uganda, especially for community-based farming groups. Despite financial and logistical challenges, the project delivered a sustainable and collaborative solution for dry-season farming.
