Water Sprinkler Irrigation


Grekkon Limited is an irrigation equipment supplier in Kenya. We design, supply, and install all types of water sprinkler irrigation systems, for every acreage and crop.  Our irrigation sprinklers for sale in Kenya are of different types, for different crops, acreage and locations.  This is why our technical or agronomy team will visit a grower who needs to install one. It is to assess the land layout and size, topography, water location, water volume, existing water pump if any, and the crop. Through this survey, we recommend the most appropriate sprinkler irrigation kit for the grower based on their budget. For instance, a grower with 100 acres of orchard will have a different sprinkler from a 100 acres of a park covered with grass. Similarly, a farmer on an 1/8 acresof cabbage will have a different sprinkler irrigation kit than the one with 30 acres of cabbage


What are the different types of sprinklers?

We have these 5 water sprinklers for sale types shown below available.  For  most, there are both metallic and plastic versions.  Metallic sprinklers have a longer lifespan, but are costlier and heavier. Plastic sprinklers are lighter, cheaper, but have a shorter period of operation. The body material does not affect the pressure rating, inlet and outlet sizes or the water discharged.

  1. Rain gun sprinklers for medium-sized to large acreage. Available sprinkler sizes are; 1″, 1-1/4″, 1-1/2″, 2″, and 2.5″. We supply and install the double nozzle PY, Atom, and flange type rain guns. The latter are for broad acreage and require  very high water volume, and high operating pressure

3. Mega-net sprinklers for small to medium-sized areas. We have the 1/2″, 3/4″ and 1″ which have a spray angle of 180 degrees

4. Micro sprinklers for orchards and small areas with a spray angle of 360 degrees. They use the least amount of pressure, and have the lowest flow rate

How to choose your water sprinklers in Kenya

  • Land size. Rain guns for large acreage, and micro-sprinklers for small plots of land
  • Crop type. Pop-ups for lawn irrigation, all other sprinklers for field crops
  • Ground elevation. Gravity power from high elevations will swing micro and impact sprinklers. Rain guns, Meganets, and pop-ups work with water pumps
  • Grower’s budget. It determines the sprinkler type and number of units to install

Our sprinkler irrigation system design considers the above 4 factors during our site visits conducted before a sprinkler irrigation system is installed

Components of a water sprinkler irrigation system

  1. Mainline. This is PVC, HDPE, or GI to supply water from the source. It will be connected directly to the sprinkler riser pipe, or to the sub-main line
  2. Sub mainline. This one is connected directly to the sprinkler rise pipe, or to the sprinkler itself from the mainline. It is also PVC, HDPE, GI or a delivery/ layflat pipe
  3. Riser pipe. This receives water from the main line or sub-main line to the sprinkler It is also PVC, HDPE,  or a GI
  4. Tripod or pipe stand. It is the sprinkler’s support structure
  5. Gate valves. They allow or block water flow to the sub mainline

A. What are the pros and cons of water sprinkler irrigation?

I. Water sprinkler irrigation advantages

  • There is a wide choice to select from
  • It is easy to install
  • It is cheaper than drip irrigation
  • Easy to move from one point of the farm to another
  • There is a sprinkler type for any crop type

II. Disadvantages

  • It is water wasteful
  • During strong winds, water distribution is uneven
  • High running cost because a water pump is needed
  • It requires labour to move it from one location to another if  it’s a portable system

B. How does a water sprinkler irrigation system work?

  • Water is pumped under high pressure from the source; tank, reservoir, lake, river to the mainline
  • From the mainline, it is distributed to the sub-main lines
  • From the sub-mainlines, it enters the sprinklers under pressure. This pressure swings the sprinkler in a circular motion
  • The sprinkler breaks the water into fine droplets, which fall on the crop

C. How do I choose a water pump for my sprinkler system?

Consider the following when selecting a sprinkler water pump

i. Pressure rating of the sprinkler. The water pump’s pressure rating must exceed that of the sprinkler to compensate for pressure losses in the piping system. Grekkon Limited’s technical team advises growers on the best match. The larger the pipe diameter, the lower the pressure loss along the horizontal pumping distance. The longer the horizontal and vertical pumping distance, the greater the pressure loos. Pressure loss during  irrigation water reticulation is also as a result of leakages along the piping system

ii. Discharge rate of the sprinkler. Like the pressure rating above, this will be higher for the water pump to cater for any fluid losses

iii. Inlet diameter of the sprinkler. That of the pump has to match this

D. What type of sprinkler is best for watering lawns?

Grekkon Limited’s pop-up sprinkler kit is the best in lawn irrigation, but also the most expensive. Other options are; the butterfly sprinkler, the impact sprinklers or the mega-net sprinklers
