Working recently with SUBTERRA, on behalf of BRL, on another big water project. The construction of a 360-metre-long HDD crossing near Narbonne will enable project owner BRL to further improve the irrigation network in the Hérault department of southern France.
The crossing, passing through clayey marl, was drilled diagonally under the River Orb and its wide riverbanks, down to 22 metres below the riverbed to carry a new DN 500 HDPE duct.
OPTIMUM engineers provided trenchless expertise prior to the drilling operations, verifying the HDD design and conducting hydrofracture modelling and analysis. Support continued throughout the drilling operations, both onsite and remotely, with OPTIMUM engineers providing the local knowledge and technical expertise necessary to successful complete this important project.
