Irrigation using Rain gun sprinklers
Rain gun sprinklers deliver high water flow rates over large areas in short duration. In large farms, use of small impact sprinklers can affect pressure and uniformity of distribution. To enhance efficiency and pipework and pumping cost, high pressure rain gun sprinklers are recommended.

Limitations of Rain Gun Sprinklers

Another challenge is wind effect which often affects distribution uniformity.
What to Consider When Buying Rain Gun Sprinklers
- Farm size – the larger the farm, the bigger the rain gun sprinkler you need for fast coverage.
- Water availability – rain guns use a lot of water. Ensure you have reliable water access.
- Soil type – Rain guns would work best for less compact soil to prevent surface run offs.
- Crop requirements – not recommended for crops known to be susceptible to fungal rot.
- Flow rate – ensure that the discharge rate of the sprinkler meets your crop water needs.
- Pump requirements – you must have a pump that matches the pressure needs of the Rain gun sprinkler you want.
How to Size Pumps for Rain Guns
Pump sizing is critical for successful irrigation.
Start by determining the sprinkler’s required flow rate and operating pressure. Then, calculate Total Dynamic Head (TDH), which includes static lift, elevation and friction loss.
Rain Guns require a pump with a head of 30 – 35 m.
Rain Gun Sprinkler Setup and Installation
- Laying HDPE pipes for delivery of water from the source.
- Mounting a water pump near the source and connecting it to delivery mainline pipes.
- Connection of ball valves for irrigation control at the mainline.
- Installation of water filter on the mainline section near the water source.
- Use of tee connector to join the mainline pipe and connect the delivery pipe that will move water to the sprinkler head.
- Connection of the delivery PE pipe with the sprinkler head. It requires a male adapter fitting.
Ensure the rain gun sprinklers are spaced at an overlap to ensure no dry areas are left during irrigation.
