With the emergence of climate change, the Australian water sector faces considerable challenges in maintaining a reliable supply of water for urban and rural users. A more variable climate will call for robust planning, efficient water markets, and prudent investment in infrastructure and water saving technologies.

Co-digesting organic waste at Wastewater Treatment Plants

While a cost for some business sectors, the rising cost of waste disposal and management is creating opportunities for wastewater utilities in terms of maximising the resource value that is recovered from wastewater and other organic waste products. Synergies conducted a comprehensive assessment of the financial and economic feasibility of two options for the implementation of co-digestion at Queensland Urban Utility’s Luggage Point Wastewater Treatment Plant. The analysis identified the option that would maximising both ...

The economics of responding to drought in Greater Sydney

Sydney Water engaged Synergies to develop an economic framework for quantifying the risks, costs and benefits of a drought management strategy for Greater Sydney. The framework examines the optimal sequence of new water supply projects as Sydney’s storage levels drop. The optimal strategy is one that avoids the risk of storages falling below critical levels (and triggering the need for very significant water restrictions), while minimising the cost of investing in capital projects that may ...

Peer Review of the Economic Analysis of the Nullinga Dam Preliminary Business Case

Synergies was engaged by Building Queensland to undertake a peer review of the economic analysis conducted as part of the Preliminary Business Case (PBC) for the proposed Nullinga Dam. The PBC identified an opportunity to expand irrigated agricultural production in the Atherton Tablelands through the supply of medium priority water entitlements from the proposed dam. The report presented to Building Queensland identified critical issues in relation to both the water demand assessment and economic analysis.

Assessing the Economic Value of Bulk Water Infrastructure in Regional Queensland

Synergies was engaged by Queensland Treasury Corporation (QTC), on behalf of the Department of Natural Resources, Mines and Energy (NRME), to develop a methodology to assess the economic value derived from the productive use of water from bulk water infrastructure in regional Queensland. The methodology was also applied to two water supply schemes – the Proserpine River and Nogoa Mackenzie Water Supply Schemes.

The economics of options for managing groundwater in Perth’s Gnangara area

The Gnangara Mound just north of Perth is an important source of groundwater for public water supply, agriculture, and other users. Groundwater levels have been falling over the last 20 years or due to declining rainfall, increased groundwater abstraction in line with population growth, and the impact of pine plantations in the area that use considerable volumes of water. Synergies was engaged by the Department of Water and Environmental Regulation (DWER) to quantify the economic ...

Case study

Economic evaluation of the Burnett River to Howard Water Supply Pipeline Project

Synergies was engaged by the Department of State Development, Manufacturing, Infrastructure and Planning (DSDMIP) to conduct the economic analysis of the Burnett River (Paradise Dam) to Howard Water Supply Pipeline Project (the Burnett River pipeline project) in accordance with the requirements for a Preliminary Evaluation as set out in the Queensland Government’s Project Assessment Framework.
