Bargo and Buxton residents’ new pressure sewerage system will collect wastewater via small tanks installed on each property.
UEA has been contracted to perform the Horizontal Directional Drilling (HDD) works associated with the transfer pipeline and is using a combination of drilling and trenching techniques to transfer wastewater via a 14km transfer main, to the existing system in Tahmoor.
UEA’s contracted requirement includes installation of 18 underbores. To deliver the works program to schedule, a minimum of three HDD rigs will be mobilised as well as a fleet of support equipment.
For the six minor HDD jobs, ranging in length from 106 to 151 metres, a DitchWitch AT3020 will be used. The remaining 12 major HDDs, of 454 to 1006 metres, will be completed using Vermeer D100x120s and D300x500s.
Construction of the transfer pipeline commenced in February 2014 and completion of drilling and trenching is expected by September 2014.
