One acre rain hose kits

Grekkon Limited’s one acre rain hose kits in Kenya installations are done by the technical team across the country. The number of rain hose pipes installed per acre is determined by the following:  

• the available flow rate, and pumping pressure from the water pump or water source. Where the flow rate and pumping pressure is high, the diameter of reach is broad, so less rain hose pipes are needed
• the diameter of the pipes. Larger diameter rain hose pipes provide more water, over a larger area, so less of them are needed

Rain hose pipes work under high gravity pressure (from 6M or 0.6bar), and with high volume water pumps. The discharge rate of the water pump is from 40 cubic litres per hour. These water pumps are surface solar, electric, petrol or diesel powered

Installation

1. Trench where the poly vinyl chloride (PVC) main line will be laid. This is not necessary for the high density polyethylene (HDPE) which are surface pipes.  PVC pipes are sub-surface pipes because they have no UV-treatment, and will thus degrade easily under the sun. HDPE pipes have UV treatment and will be surface pipes
2. Connect the  PVC or  (HDPE) main line to the water pump or high tank. This pipe evacuates water from the source to the farm and is the largest in diameter. The larger the pipe diameter, the more the water it delivers. .
3. Join the HDPE or PVC sub-main line to the main line. The sub-main line is smaller in diameter, and so carries less water. It is joined to the main line through PVC or HDPE accessories such as; tees, elbows, saddle clamps, adaptors or valve sockets
4. Connect the rain pipe to the sub-main line or the main line where a sub-main line does not exist. This is done with a rain hose connector or a saddle clamp
5. Spread the rain hose along the length, and close the terminal end with an end cap
6. Connect one rain pipe to another with a connector

  A drilling tool is the only tool used when installing a rain hose kit. This is to create an opening on the main or sub-main line to insert the rain pipe ball valve

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

FAQs

a. What is the difference between a rain hose irrigation system and a sprinkler system?

• The technology. The rain pipe irrigation system is designed using nano technology
• The mode of spray. A sprinkler sprays its water in one direction, a rain hose pipe sprays in 3 directions (vertically, horizontally, and diagonally)
• Placement. A sprinkler is placed upright on the surface or sub-surface (for pop up sprinklers). A rain hose is laid on the ground

b.  What is the pressure in a rain pipe?

The minimum operating pressure is 30M head / 3 bars

c. What is the spacing for rain hose irrigation?

The distance from one rain pipe to another is from 1.5M depending on the operating pressure, and pipe diameter
