Water

Water

Naturally, TWE relies on water to grow our grapes and make our wine. We consider water to be a precious and fundamental resource, and we are committed to managing its use carefully. We recognise that water availability, use and conservation are ongoing challenges for the wine industry and other industries that use this precious resource in production. Actions taken to reduce water use and improve efficiency include:

Improvement to process

In our vineyards, TWE uses drip irrigation, drought-resistant rootstocks and grape varieties appropriate for the environment, recycled municipal water where available, and places compost and mulch under vines to retain soil moisture, as required. Across our winery network, we closely manage winery wastewater and reuse it for vineyard irrigation when quality permits.

Investment in innovation and technology

At selected vineyard sites TWE has the capacity to monitor soil moisture and visualise water stress. We are trialing the use of thermographic cameras, hyperspectral imaging and real-time evapotranspiration monitoring to enhance these processes. Across selected winery and packaging sites, sub-metering and real time monitoring technology has been deployed to identify and reduce water intensive activities or leaks. ‘Pigging’ technology, which pushes wine with inert gas instead of water, has been installed at frequently used packaging transfer lines.

Water trading

TWE owns water entitlements (separate to land title) in Australia and the US (where required). In Australia, water rights are traded to manage water security.

Repairs and maintenance

TWE has replaced sprinkler frost protection in several vineyards with automated frost fans to reduce the amount of water used when protecting our vines from frost events. In our winery and packaging network, there has been a focus on updating barrel washers to more water efficient models.

Awareness and education

Through development of management systems, such as Sustainable Future, and our online data repository and reporting tool, which measures water use and helps to engage our people on conservation techniques.

Research, development and extension

Collaboration with research institutes on projects in relation to water efficiency and climate change adaption.

Over time, water usage is largely trending downwards, with water efficiency having improved by 7.27% since F15.
