Rain hose Irrigation

Share

Grekkon Limited is the commercial pioneer of rain hose irrigation kits in east Africa, and is the largest supplier and installer of rain hose systems in the region. This is done through the company’s 7 branches countrywide in Nairobi, Mombasa, Kisumu, Eldore, Nyeri, Meru, and Nyahururu. Before installing  a rain pipe irigation system in a farm, we conduct a site visit to assess:

  • the water volume available 
  • crop acreage
  • crop type
  • land dimension
  • farm topography and lay out

This is the information that guides us on the design of the irrigation system to set up. If the water volume for instance is low, we recommend a more water efficient method such as drip irrigation. Alternatively, we’ll advice on a water harvesting technique to increase the water volume

 

Rain hose pipe

What is a rain hose irrigation system?

Rain hose systems are a new overhead way of watering crops intensely under moderate pressure. Each kit has a 100M long pipe as the main accessory. The pipe is sequentially perforated at determined intervals using Nanotechnology to create tiny holes from which crops are irrigated.

What are the other components of a rain hose kit?

1. End-caps. They close the end of the pipe to prevent further water flow
2. Starter off-takes. They connect the rain pipe to the PVC or HDPE main line that supplies water to the rain hose from a water pump or highly elevated water tank
3. Pipe connectors. To connect one rain hose pipe to another
4. Mini valves. To control water flow to the rain hose pipe


The diameter of the pipe ranges from 32mm to 50mm. A grower chooses the preferred size based on crop water needs and area of irrigation. For instance, a farmer with 1 acre of the crop will comfortably water with the volume delivered through a 32mm rain hose pipe. Another grower with 5 acres will better irrigate with a 50mm rain hose pipe. An acre of crop uses 800 meters of 32mm rain hose pipes, 600M of 40mm pipes, and 400M of 50mm pipes

 

 

What is the price of a rain hose irrigation kit?

 
Diameter size
Flow rate per 100M Price in KES
32mm or 1″  13 cubic litres per hour KES 4,500
40mm or 1-1/4” 16 cubic litres per hour KES 5,500
50mm to 1-1/2″ 22 cubic litres per hour KES 6,500

 

Rain hose irrigation system requirements

  • The system requires a pressure head of 30M, and above
  • When using a water pump to power the rain hose irrigation kit, the discharge rate should be from 45 cubic litres per hour 
  • The rate of water discharge is determined by the diameter size, and number of pores on the rain pipe. For instance, a rain pipe with 5 holes per cluster discharges less water than the one with 7 holes in a cluster
  • It irrigates in opposite directions at a radius of 3M for the 32mm pipe, 5M for the 40mm pipe, and 7M for the 50mm pipe
  • The vertical height of this water jet is 1M

 

Irrigating a newly transplanted crop with a rain hose pipe

How to assemble a rain hose irrigation system kit

1. Lay the mainline

This is the pipe delivering irrigation water to the farm from the pump. Your mainline will be larger in size than the rain hose pipe. So if your rain hose pipe is 1” for instance, use a 1.5” or 2″ main or sub mainline

2. Connect to the mainline

Make a 1” insertion on the mainline and attach the off-take connector. The size of the insertion is as per the size of your off-take

3. Hose connection

Attach the rain hose pipe to the off-take connector

4. Hose to hose connection

Use the connector to attach one rain hose to another

5. Endcap

Insert the end cap at the end of the hose

This irrigation system is used in the following areas and on these crops

  1. Crop nurseries; vegetables, fruit trees, forestry
  2. Short vegetable crops (knee-high and below); cabbage, lettuce, broccoli, kales, spinach, collards, broad beans, carrot, strawberry, and others
  3. Pasture; grass and legumes

When choosing the crop to irrigate using this method, consider its susceptibility to foliage fungal infections predisposed by leaf surface wetness. Tomato, potato, peppers, peas, green beans, and chili easily succumb to foliage fungal infections when overhead or a rain hose system is used for a long time

Rain Hose Versus Drip Irrigation

  1. Rain pipes irrigate in an overhead fashion, drip lines irrigate to the root zone
  2. Drip tapes are water efficient, rain hose kits require large water volume 
  3. Rain pipes have a higher pressure requirement than drip pipes
  4. Drip lines have emitters, while rain hose kits have pores done with nano technology
  5. The discharge rate for drip lines is 1.2 to 4 litres per hour per emitter, while the rain hose pore’s is from 7 litres per hour per emitter
  6. The cost of a drip kit installation per acre is from Kes 100,000, while the rain hose is from Kes 55,000
  7. The rain hose pipe’s minimum diameter is 25mm/ 3/4″, while drip tape’s is 8mm
