Irrigation dos and don'ts for farms in Kenya

Do these things before buying

• Measure the field and map crop rows, beds and elevations
• Confirm dependable water availability and source quality
• Check required flow and pressure for the irrigation devices
• Plan filtration, flushing and maintenance access
• Compare complete system scope—not only the pump or dripline price
• Ask for a written equipment list, assumptions and installation scope

Avoid these common mistakes

• Do not select a pump from horsepower or acreage alone
• Do not assume every crop or soil needs the same emitter spacing or watering schedule
• Do not operate all zones together unless the design and supply support it
• Do not ignore filters, pressure regulation, flushing points or gauges
• Do not mix pipe, fittings and components without checking size, pressure rating and compatibility
• Do not leave leaks, clogged filters or damaged lines unattended
• Do not fertilise through irrigation equipment without compatible products, correct setup and safe handling guidance

During installation and operation

Flush pipes and laterals before normal operation, test each zone and inspect for leaks or pressure differences. Keep records of operating times, maintenance and recurring faults.

Monitor soil moisture and crop response rather than relying only on a fixed timer. Irrigation frequency and duration vary with crop stage, soil, weather, system performance and water availability.

A simple pre-start checklist

• Water source has adequate supply
• Filters are clean and correctly installed
• Valves and zones are labelled
• Pressure and flow are within equipment specifications
• End lines and flushing points are accessible
• Leaks and damaged fittings are repaired
• Operators know how to stop the pump and isolate the system
