Buckle, James (2017) Identification of Infiltration within Albury Sewerage Infrastructure. [USQ Project]
Abstract
Inflow and Infiltration (I/I) into a sewerage network is defined as the ingress of storm water and ground water into a sewerage network. Albury City Council in recent years has seen the volumes of water moving through their Waste Water Treatment Plants increase, and this has led to a renewed effort to curb I/I within the Albury sewerage network.
A study was completed in 2016 ‘Sewer Infiltration – Analysis, Impacts & Mitigation for a Growing City’ completed by Rory Hutchinson and this quantified Albury’s issue by looking at individual catchments. The study determined the worst catchment in relation to size and volumes of I/I produced. With the problem quantified, there was a need to examine how Albury City was to identify the sources of the I/I occurring.
Within the literature review, case studies from around the world and different source detection methods were analysed. Four identification measures were chosen for testing including smoke testing, electronic scanning, CCTV inspections and visual inspections. These identification measures were implemented across sewerage catchments 16 and 49. Catchment 16 was chosen because it had the highest volume of I/I in relation to catchment size and 49 was chosen due to the pump station operating when no properties were connected.
The different source detection methods were evaluated based on the criteria of cost, effectiveness and suitability. The effectiveness of the testing is critical to its operation and producing a result along with it being financially viable on a large scale. The inspections also have to fit in with Albury City’s operational structure in regards to not requiring strict oversight, providing automated results with minimal processing.
From the tests performed and the following analyses it was determined that smoke testing along with CCTV inspections are the best method of identifying I/I within Albury City’s sewerage infrastructure on a large scale.
