Afriq Water Quick Coupling Irrigation System

Sprinkler Irrigation with Quick Coupling Fittings

irrigating for a greener tomorrow

Afriq Water's Quick Coupling irrigation system is a reliable, durable and cost effective irrigation system that offers a cots effective alternative to the old fashioned steel pipe systems.

The system can be utilised to compliment and support other irrigation systems e.g. dragline systems and drip line systems as lateral lines; or alternatively to be used on its own as a sprinkler system or as main lines for water transportation

The smooth interior ensures low frication loss, thus increasing the efficiency of the system. The system consists of pipes, normally 6m (but various pipe lengths available) which are joined by ingenious quick coupling latch fittings.

The fittings have gaskets that allows for leak-free joints that can be used in all topographical conditions. The couplings are orange, which assists with visibility in fields. Because the system is manufactured of HDPE it is light weight and can easily be moved and assembled by one person.

The system has been used for the past 40 years in all climate conditions, from harsh frozen winters to extremely hot summers. It is UV protected and is very durable; the Southern African weather and direct sunlight poses no challenge for this unique product.

Design a Sprinkler System

When designing a system layout for the irrigation of a field or area there are some necessary steps that needs to be taken into account during the process.
Here are some important points to consider:

  • Calculate the available water to ensure that you use what is available. Do not overdesign the system. Typically using a centre feed layout is more efficient than using a side feed design, the biggest advantage being the shorter laterals ensuring reduced friction losses that could cause uneven water distribution.
  • Determine the maximum amount of sprinklers that could be fed with the available water. Divide the available water with the flow rate of the sprinklers as supplied by the sprinkler manufacturer. For example: water available is 4750 l/hr, the flow rate of the sprinkler is 1400 l/hr, 4750/1400 = 3.39. The max amount of sprinklers that could be supplied is 3. If need be to increase or decrease the flow the nozzle size could be adjusted.
  • Measure the lateral length of the area to be irrigated. Divide the length of the area by the radius of the sprinkler. Area = 100m, radius of the sprinkler is 15m, 100/15 = 6.66, this is increased to the next full number being 7 in this case. To determine the amount of sprinklers needed, deduct 1 from this number being 6. If a centre feed system are used two sides of 3 sprinklers will be sufficient. Using a centre feed system shortens the laterals. A side feed system would also have required 6 sprinklers from the main line but the longer laterals would cause more friction loss, maybe requiring thicker laterals and main line.
  • If the water supply is not enough to supply the 6 sprinklers needed the line could be split into two sections at the cross where the laterals join the main line by means of a cross valve. The line will be split into two 3 sprinkler lines. Another option is to decrease or increase the nozzle sizes to optimize the available water; the number of sprinklers needed to fit the lateral length needed could be increased or decreased. Reducing or increasing the pressure could adjust the radius of the sprinkler affecting the spacing.
  • The laterals are spaced at the same distance than the radius of the sprinkler along the main line. The laterals and the layout of the laterals are kept uniformly parallel along the main line. More than one row of laterals could be used together if the water supply is sufficient, this could shorten the irrigation time schedule.
