Performance & Hydrogeological Review of Waikerie & Woolpunda Salt Interception Schemes
Client:
SA Water
SA Water engaged Fifteen50 to perform a technical review of the efficiency and effectiveness of salt interception scheme infrastructure in Waikerie and Woolpunda over the review period of 1 July 2013 to 30 June 2021, including hydrogeological conditions and applied management practices.
This required the collation, analysis and reporting of key datasets, using an evidence-based methodology to assess performance indicators and develop recommendations that may result in improvements against scheme management objectives.
Fifteen50, with the assistance of CDM Smith, conducted a site visit, and also provided detailed analysis on the operating environment (hydrogeological context), scheme management and scheme performance. Key deliverables included a presentation of key findings to SA Water and the Murray Darling Basin Authority and the submission of final reports for each of the scheme.

Run of River Survey Analysis and Report
Client:
SA Water
Fifteen50 was engaged by SA Water to process the survey data, analyse results and report the finding of the 2021 Run of River salinity survey which encompassed Lock 1 to upstream of Lock 6 of the Murray River.
This involved undertaking a literature review of previous reports and research papers to consider the mathematical, numerical and computational tools pertinent to each methodology and their advantages and disadvantages prior to adopting a methodology that is most appropriate for a more improved definition of salt inflow.
GIS computations of the river bathymetry, bank elevation and detailed knowledge of calibration and mathematical equations were required to undertake the analysis. Fifteen50 provided detail for all steps of data analysis undertaken along with assumptions and calibration methods in the final report.
The final report will be used by SA Water and the Department for Water and Environment to assess salinity trends in the river and review operational targets in salt interception schemes and groundwater management schemes to achieve environmental objectives.

Hydrogeological Pump Test
Client:
Andrew Peace Wines
Andrew Peace Wines (APW) engaged Fifteen50 to undertake the project management and data collection required to complete a Groundwater Impact Assessment (GIA) in the Swan Hill region of northern Victoria.
Fifteen50 worked closely with Groundwater Enterprises and Hydro Terra Pty Ltd to scope and undertake the 14– day pump test ensuring all sensitive environmental receivers were identified, understood and monitored during the pump test period.
Analysis of the pump test data and assessment of potential impacts on all surrounding bores, rivers and streams supported a license application to the Regulator for a deep lead bore in the area.
Fifteen50 was engaged due to our understanding of groundwater licensing and our fundamental understanding of the importance of accessing sustainable water sources for enhancing production of viticulture and other primary production.

Project
Nimmie-Caira Site Supervision and Contract Management
Client:
Department of Industry (NSW)
The Nimmie-Caira Project, a $180 million water saving project in the lower reaches of the Murrumbidgee River, between Maude and Balranald. The property spans over 84,000 ha of the Lowbidgee floodplain, incorporating high value wetlands.
The project aims to balance environmental and Aboriginal cultural heritage protection with commercial use. After purchase of the property and water by the NSW Government, and development of environmental and land management plans, the final stage of the project was to reconfigure existing infrastructure. This reconfiguration aimed to enhance delivery and use of environmental water and to provide an efficient delivery network for stock and domestic water supplies.
Fifteen50 provided full-time construction contract management and site supervision for the construction of the Nimmie-Caira Water Infrastructure and Stock and Domestic Pipeline works.

Salt Interception Scheme Pipeline Replacement GIS Risk Prioritisation Tool
Client:
SA Water
SA Water engaged Fifteen50 to create a GIS-enabled risk prioritisation tool for pipeline replacement associated with salt interception schemes operated and managed by SA Water.
This involved developing a methodology to identify priorities for pipe replacement of salt interception scheme pipelines, informed by asset risk management principles from SA Water and industry standards. For a more robust likelihood of failure assessment, Fifteen50 interrogated the information that is used to quantify estimated remaining life by reviewing existing database information against as-constructed drawings across all schemes, as well as obtaining information on history of failures.
SA Water’s risk and opportunity impact criteria matrix informed the selection of impact of failure parameters which were then adapted to a Salinity Operations context. Combinations of scoring and weighting assumptions were sensitivity tested to finalise parameter selection and scores. The end result was a fit-for-purpose risk rating of pipeline segments in a complete database that is updateable and can be used for long-term expenditure forecasting.

River Murray Operations SCADA Automation Business Case
Client:
SA Water
SA Water engaged Fifteen50 to perform a detailed options analysis on different SCADA modernisation approaches to form a business case for suitable assets in the River Murray Operations arm.
This involved reviewing the telemetry options analysis report and capital costings by telecommunications engineering consultants, as well as liaising with SA Water’s River Murray Operations, IT and SCADA teams to understand their existing operations and capability.
This culminated in budget cost estimates which captured the opportunities and impacts to SA Water operations and maintenance in the long-term based on varying levels of telemetry control and responsiveness. The business case was accepted by the Murray Darling Basin Authority and the modernisation upgrades have been incorporated into SA Water’s renewal and replacement works program.
