Trenchless technology is not only respectful of people and the environment, it is the logical and economical solution in the current framework. It includes several methods for the rehabilitation and new installation of pipes that avoid, as far as possible, ditches on public roads and shorten execution times.

A project with a worldwide impact

Alzira, a small town near Valencia, was the beneficiary of a unique horizontal directional drilling (HDD) project using DN 900 PHD-type ductile iron pipe with a 25 bar design pressure.

Horizontal directional drilling: 456 m of buried pipeline with large-diameter pipe

Part of the route of the new pipeline, with a nominal diameter of 900mm for the supply of drinking water to the Ribera region, involved crossing the River Júcar, the Valencia – Alicante railway line and an industrial building.
