  • Village water supplies
  • Fire mains
  • Desalination pipelines
  • Turkeys nest
  • Dewatering
  • Tailings dams
  • Evaporation ponds
  • Wash down bays
  • HDPE lining

UON has a dedicated Fabrication unit able to create manifolds and an assortment of fittings including lobster back elbows and T intersections.

These standard and bespoke fittings ensure the intricacies of every project is catered for, with reduced lead-times, shorter project durations and safer operations.

UON constructs and installs intricate HDPE pipeworks of all sizes and pressure ratings, ranging from Dn63mm to Dn1200mm.

UON has invested in equipment to support the safe and efficent delivering of projects, with trenching machiery that can dig 1500mm wide and up to 4500mm deep, through all ground conditions.

Designed for extreme soil and rock conditions, the trencher produces fines to a sand texture.
With a low environmental footprint, the high volume trenching generally produces a solid foundation, resulting in labour, time and cost savings.


UON’s capability for earthworks covers all aspects of mine water infrastructure, enabling project delivery to be managed in-house.

The delivery of large and detailed works packages include:

  • Tailings dams
  • Settlement ponds
  • Transfer stations
  • Evaporation ponds
  • Turkey nests
  • Pump pads
  • Road crossings
  • Rail lines

UON offers a range of HDPE Lining and Geomembrane Lining Systems.

Lining materials and geomembrane are sourced as part of the project management process, ensuring quality management and shorter lead time.
