Background
Omondi Farm, located in western Kenya, depends on boreholes and seasonal rivers for crop irrigation. The farm cultivates 6 acres of vegetables (tomatoes, sukuma wiki, onions) and requires a reliable water source during the dry season.
Flowatt Solution: 1000W 4-inch Solar Submersible Pump
The farm adopted the 4SSH3.6/100-D90/1000, installed with the following configuration:

Why This Pump Was Selected
- Wide voltage tolerance provides stable flow under varying sunlight
- 100m head capability matches the farm’s 70–100m dynamic borehole
- 304 stainless-steel construction suitable for mineral-rich borehole water
- Helical rotor design ensures strong pressure and smooth flow at deep heads

Benefit |
Description |
|
Stable Irrigation Output |
Supplies 12,000–16,000 L/day, enough for 6 acres of drip irrigation. |
|
Zero Fuel Cost |
Eliminates diesel expenses (previously 7,000–9,000 KES/month). |
|
Reliable Deep-Well Performance |
Strong performance at 85–90m TDH, ideal for 70–100m boreholes. |
|
Improved Crop Yield |
Consistent water supply boosts crop uniformity and reduces dry-season losses. |
|
Low Maintenance |
BLDC motor + 304 stainless-steel design ensure long service life with minimal servicing. |
Customer Feedback
“The Flowatt 4-inch pump has transformed our irrigation. Our borehole is 95 meters deep, but the pump fills the 5,000-liter tank before noon. We switched off the diesel engine for good. The crops now receive consistent water, and our costs have dropped significantly.”
