irrigating for a greener tomorrow
Since early 2020 Afriq Water has shared with you that they are in process to import a top of the class dripline manufacturing machine. The benefits of manufacturing on site as opposed to imports, are plenty, most importantly there will be a cost saving.
Secondly there will be certainty of stock availability. What is not on the floor, will be manufactured within a week or two, addressing the irrigation needs of the farmer or retailer quickly and effectively.
Why Drip Irrigation?
Southern Africa, and in fact most of Africa is a water scares region. Large numbers of people struggle to have access to clean drinkable water. It is the responsibility of each user of water to use water as wisely as possible. In terms of irrigation, the most effective way is drip irrigation. Drip irrigation is the most efficient water delivery system for irrigation. It delivers water directly to the plant's root-zone, in the right amounts, at the right time. This ensures that each plant gets the exact amount of water, at the right time for optimal growth.
Drip irrigation is not only the most effective way of delivering water, but also the best possible way to deliver water soluble fertiliser and other plant requirements. Farmers can achieve optimum yields while saving water, fertiliser, and labour costs.
Selection of dripline
The farmer selects the emitter spacing and wall thickness of the dripline according to his needs. The emitter spacing is determined by the requirements of the crop, plant spacing, and the soil's physical traits.
The dripper is selected with a specific flow rate suited to the crop and conditions. Each emitter discharges the exact amount of water and fertilisers (if applied), resulting in the consistent application of water and nutrients directly to each plant's root-zone, across an entire field.

For Afriq Water the wait is finally over, and since October 2020 Afriq Irripipe has started to manufacture on-site in Gauteng.
Afriq Drip driplines are manufactured to cover a broad range of irrigation needs:
- Emmitter spacing: from 20cm – 1,2m (30, 45 and 60cm will be carried as normal stock items)
- Drippers: 1 l/h, 2 l/h, and 4 l/h
- Wall thickness:
Light - 0.15mm – 0.20mm
Medium - 0.30mm – 0.60mm
Heavy - 0.90mm – 1.1mm
The Benefits of Dripline
- Lower water consumption.
- High crop yields and quality.
- Easy installation and dismantling.
- Irrigates uniformly on any topography and soil type, with precise water distribution and less puddling.
- Energy savings: drip irrigation works on low pressure.
- Efficient use of fertilizer, fungicide, and insecticide with no seeping.
- Reduced weed growth.
- Less dependency on weather conditions which leads to greater stability and lower risk.
Benefits to the Plants
With sprinkler and flood irrigation plants often get an "overdose" of water once every few days, as opposed to a steady and constant application of water. As a result, the plant/crops suffer bouts of drought, which is not ideal for plant development and growth. Dripline can apply water and nutrients frequently and in small doses, ensuring the best growing conditions that helps produce the highest yields possible.
Plants benefit from dripline because the consistent availability of water and nutrients, with tailored doses of water and nutrients for the plant's development needs. All types of crops are suitable for this method of irrigation. From field crops such as maize, soya bean or sugarcane, to vegetables and tree crops.
The initial layout of dripline can be more costly than other irrigation methods, but farmers should calculate return on investment over a longer period of time, taking into consideration increases in crop yields while saving on inputs (water, fertiliser, energy and labour). Dripline can pay for itself in a relatively short period of time and ensure higher profit. With 95 - 100% water-use efficiency, this method of irrigation is known to be one of the most efficient irrigation methods. This is compared to sprinkler irrigation that offer 80 - 85% wateruse efficiency or flood and furrow irrigation that offer 60 - 70% water-use efficiency.
- Do not exceed the limitations as indicated on the information sheet, eg max lateral length and max operating pressure.
- Roll off in the direction as indicated on packaging.
- The dripper outlet must be on top of the dripline.
- Avoid damage to the dripline during installation and do not twist, pull, cut, or perforate it.
- Dripline can be installed on the surface, under mulch or subsurface below ground.
- Use appropriate fittings to prevent leaking and joining of pipes.
- Dripline should be under acceptable tension to allow for expansion and contraction because of temperature variations.
- Main and secondary lines should be flushed before connecting the dripline.
- The dripline should be put under pressure within 24 hours after installation.
- Ensure depth is sufficient to prevent damage during working the ground with farming equipment but also to ensure that the water reaches the roots of the crop.
- Utilize air relief valves to prevent a vacuum inside the dripline.
- Prevent root intrusion by using a suitable herbicide.
- Regularly check flow at end of dripline to confirm water flow to the end, endcap can be replaced by a mini flush valve.
- It is advisable to regularly flush the dripline and filtration system.
- Water must be clean - install a proper filter, either screen, disc or sand.
- Rodents, roots and insects can damage the dripline, install proper preventative measures.
- Use only water-soluble fertilizers and flush the system before shut-down.
- When removing dripline from the field ensure to use a spool. Do not bundle the pipe.
For drip systems, filters are an absolute necessity
