Dubbo Sewerage Treatment Plant Major Upgrade

At $24 million, the major upgrade of Dubbo’s Sewerage Treatment Plant is the biggest single capital works project ever undertaken by Dubbo City Council. With the aim of coping with the sewerage infrastructure needs of a growing population, the project involves building an additional bioreactor and two clarifiers, with scope for a third clarifier in the future. On completion next year, the plant will be able to support a population of 55,000 people.

Barnson is providing survey services for earthmoving and pipe and services installation for A1 Earthworx in a sub-contracting role for the project. The team has provided compaction testing for earthworks, compiled ITP and survey reports and provided civil engineering design and earthwork quantities.

The biggest challenge has been coordinating and allocating time for the project, which ranges from needing staff attention for 40 hours per week down to two to three visits spread over 15 hours, generally at short notice. This is a job that has called on Barnson’s project management resources to ensure that regular phone contact, site visits and meetings are coordinated to keep everything running smoothly.
