The current situation of water resources has led over the past decade and will soon lead to great development of new irrigation techniques joined by the common aim of saving and optimizing the use of water. In this context the use of PVC-U piping for carrying water under pressure has undergone a great increase thanks to the construction of new sprinkler pipe systems for irrigation use and to the optimum quality/price ratio offered by this material. The Blu Tech Evolution pipes supplied with the prefitted Power Lock connection system in the range of diameters up to 630 mm provide an excellent solution today for designing both secondary distribution networks and for the main feed systems.
