Wastewater Network Upgrades

As part of the Welsh Government’s A465 dualling, Velta was appointed to install new water supplies, including deep excavations, road crossings, and new rising mains.

In Phase 1, we successfully completed a 46m-long pipe crossing beneath the A465. A design change required a depth increase from 2m to 4m, and Velta quickly implemented temporary works and groundwater management solutions to maintain safety. The work was completed over a weekend road closure, with the carriageway fully reinstated 24+ hours early.

Phase 2 involved the installation of 200m of rising main along local roads, while Phase 3 involved a 60m-long pipe crossing below the A465 and through adjacent farmland. In both cases, Velta’s efficient use of pre-booked road closures ensured minimal disruption, with all work delivered safely and on budget.
