No installation challenge is too great for us to accept, whether a 760-meter pipeline across uneven terrain or a 1.6-kilometre leak-free water pipe.

760-meter irrigation pipeline across uneven terrain
We had to install a 760m irrigation pipe along an uneven terrain where digging a trench to bury it was impossible.
We used HDPE pipe for this project for several reasons:
- HDPE pipe is flexible. It has a bending radius of 20 times the outside diameter of the pipe, making it ideal for installations that are not level.
- It is very durable and has high tensile strength.
- It was a trenchless installation, leaving most of the pipe exposed. We had to ensure the pipe we used would endure sun exposure. HDPE pipes, with a lifespan of between 50 and 100 years, were ideal for this project.
- HDPE pipe is lightweight, requiring no heavy equipment to install or move it to the terrain where we had to work.
760-meter water pipeline
Our client needed to transfer water from one side of their estate to the other for irrigation purposes. They wanted a dependable, permanent solution that does not require much maintenance.
We used HDPE pipe
The pipe, covering a distance of 1,6km, had to be installed in a trench. We used 110mm HDPE pipe
Although we buried almost the entire length of the pipe in a trench, there were several reasons why we decided to go with HDPE pipe rather than PVC:
The HDPE pipe we used is available in 50 m lengths. It was ideal for installation across such a long distance as there would be a limited number of welds and no couplings. Furthermore, it is very flexible and durable, and unlike PVC, it won’t crack or break if a heavy load is applied.
Buttwelding
We buttwelded the pipe to ensure it remains leak-proof and reliable, even in pressurised conditions. The same can’t be said of glued PVC couplings.
