Population growth and tourism have placed pressure on the Lower Great Southern Towns Water Supply Scheme (the scheme). Additional water supplies are needed to provide long-term water security for more than 40,000 people throughout:
The Mitchell River Water Supply System in East Gippsland has faced ongoing water security issues. The region has experienced severe climate events in the past and needs a more resilient water supply.
The business case will investigate constructing a new storage basin to the north of 2 existing storages in East Gippsland. It is anticipated that a new storage basin would:
Wangaratta’s water supply is unreliable and regularly subject to drought, flood, and the effects of bushfires. There are currently around 30,000 residents who rely on the water supply network in the town and nearby areas. This lack of water security can result in limited population growth, reduced liveability and an increased threat of water restrictions.
Tasmania’s current North West Water Supply Scheme has insufficient infrastructure to meet growing demand. The Isandula Dam is at risk of dam failure, posing a threat to the region’s water supply. The Scheme currently supplies water to more than 55,000 residents in North West Tasmania, including the townships of:
The detailed business case will investigate options to determine the preferred solution. The proposed project is expected to:
The rural village of Tabulam, in the far north-east of New South Wales, has never had a town drinking water supply, with residents entirely reliant on rainwater tanks for household supply. The absence of a safe and reliable drinking water supply has left the community in a state of low water security and with poor water quality, including exposure to pathogens and potentially toxic blue green algae.
Population growth, tourism, mining and agribusiness are all expected to increase pressure on Orange’s water supply. The business case will explore the potential of purified recycled water to address long-term water security issues in Orange.
The project will explore the feasibility and benefits of:
Population growth has put pressure on town water supply systems in the Far North Coast region of New South Wales. Due to climate change, extreme dry periods are likely to increase and place further pressure on the region’s water supplies.
The preliminary business case will investigate the feasibility of several water supply options to improve the region’s climate-resilience. Options for consideration include:
The Bermagui town water supply system has been identified as having the greatest unaddressed water security risk in the South Coast region of NSW. The preliminary business case will explore infrastructure and non-infrastructure options to address water security and shortage issues.
Bermagui draws its town water supply directly from the Brogo River, with releases supplied by the regulated Brogo Dam. The preliminary business case will investigate:
The current rainfall-runoff-recharge relationships for parts of South Australia were established in the late 1990s. This relationship was only calculated for the Mount Lofty Ranges’ surface water catchments even though, with some adjustments, it was applied to similar catchments in other parts of the state.
This project aims to develop new state-wide rainfall-runoff-recharge relationships that incorporate the impacts of climate change (particularly since the onset of Millennium drought) on this relationship across the state.
The town of Elliston, located on the Eyre Peninsula, completely depends on the Bramfield groundwater resource for its water supply. This resource is diminishing in size due to the impacts of climate change.
This project will research and investigate the long-term viability of the Bramfield groundwater resource. It will determine the longevity of the groundwater resource in a drying climate and the need for a climate-resilient water supply. This will help inform the type of infrastructure required, which may include:
