UEA has recently completed a sewer pipe bursting upsizing project in Orange NSW, 250 kilometres west of Sydney, with a population of approximately 40,000 residents. Orange City Council required an upgrade of the existing Earthenware vitrified clay (VC) sewer gravity main across Margaret Stevenson Park in order to enable a larger flow of sewer due to population growth and development in the region.
Pipe bursting is a trenchless technology method of replacing underground pipelines without use of a conventional construction trench.
Not all trenchless techniques and technology are created equal. Each has its own set of benefits and drawbacks and selecting the right method for the job is an important part of the planning process for trenchless contractors.
UEA Trenchless has recently completed a pipe bursting contract for Dubbo City Council for the renewal of 357 metres of 100mm water main with PN16 125mm polyethylene pipe.
UEA Trenchless has recently purchased two new pipe bursting machines – a Grundoburst 800G and a Vermeer/Hammerhead 50T Hydraulic burster with power pack. Pipe bursting is an eco friendly trenchless technology that replaces the existing host pipe by displacing its fragments into surrounding soil while simultaneously pulling in the new product pipe of the same or larger diameter into the void created.
UEA Trenchless has recently been awarded a design and construct pipe bursting contract in South East Queensland. UEA will renew 1100m of 150mm AC/PVC sewer rising main with 250mm PE PN16 using pipe bursting methods. The contract also includes the construction of a discharge manhole at the end of the line.
