In this drip irrigation lines and pipes piece, we will answer commonly asked questions in relation to drip irrigation
1.What is drip irrigation tape?
This is a flat thin walled LLDPE material tube with sequential emitters for irrigation
2. How long do you water with drip tape?
This depends on the crop water need at the time of irrigation. It ranges from 25 minutes to 1.5 hours. It is recommended to irrigate daily over a short duration with the same amount of water to keep the crop happy
3. Can you re-use drip tape?
Yeas you will over several growing seasons. The thicker the wall size, the longer the re-use period
4. What is the maximum length of a drip irrigation line?
1,000M
5. How much water does drip tape put out?
This depends on the emitter specifications. We supply 1.5L/ hour, 2L/hour, and 3L/hour emitters in our drip tapes
6. How much do drip lines cost?
Grekkon Limited’s double emitter drip irrigation lines and pipes for sale in Kenya tapes are categorised by thickness; 0.3mm, and 0.4mm. Both are 16mm in diameter, 1,000M long and with a choice of emitter spacing as 15cm, 20cm, and 30cm
Cost of drip irrigation tapes
| Thickness | 0.3mm | 0.4mm |
| Price | KES 7,500 | KES 8,500 |
The choice of drip line thickness depends on
- is it for out door or greenhouse installation? 0.3mm is fine in the greenhouse because it is no directly exposed to sunlight
- radiation level. where the sun’s radiation is high, 0.4mm is better
7. How much does it cost drip irrigation for 1 acre?
This depends on the crop type. Different crops have different drip irrigation piping requirements

10. What pipes size should I use for drip irrigation?
There are 3 lines in an irrigation set-up
- main line. This one delivers water to the farm from the source; tank, water pan, lake or river. It is the largest
- sub-main line. It is connected to the main line to supply water to the drip irrigation tubes. It is lesser in diameter than the main line
- drip irrigation tape. it supplies water directly to the crop
The pipe size is a factor of acreage. The main line diameter size on 10 acres is larger than the main line diameter size on half an acre of drip irrigation. These pipes are either HDPE or PVC types
