Water Sources

Water is a precious resource used in our grape growing and winemaking. TWE’s vineyard, winery and packaging centre water is generally sourced through a mixture of:
  • Recycled water (incoming and onsite)
  • Irrigation channel or pipe
  • Municipal mains
  • Surface water (rivers, creeks and dams)
  • Stormwater
  • Groundwater, bore or well
  • Trucked in or bought water

People

TWE focuses on engaging its people through its Sustainable Future program. This has led to both process and behavioural changes that have had a significant contribution to TWE’s daily water conservation. Examples include:
  • collection and re-use of  grey water for secondary purposes;
  • sweeping rather than hosing down winery floors during cleaning;
  • water efficient barrel washing methods;
  • night cooling of wine tanks resulting in water usage efficiencies; and
  • improved reporting of leaks and maintenance issues.

Infrastructure and technology

TWE invests in various infrastructure upgrades designed to replace less efficient equipment. Upgrades include installing both scrubbers and high efficiency barrel washers, improved refrigeration equipment and control technology as well as rainwater capture and storage installments, such as tanks and vineyard drain tiles.

TWE also deploys drone technology to complement existing aerial imagery at selected vineyards to easily and accurately locate zones of water stress, leaks, and soil variation. This allows our people to more rapidly respond to and manage water related incidents.

Across TWE’s winery and packaging network, the Company continued to install technologies that enable major water savings. These include ‘pigging’, which is a process that uses gas instead of water to push wine through pipework, and pulse cooling, which conserves water at the refrigeration process.

Beringer Winery Grapes 

Beringer captures rainwater

TWE is committed to reducing its environmental impact over time and continually looks for ways to utilise natural resources more efficiently.

 

To reduce the amount of groundwater being pumped from wells at our Beringer winery (United States), the site repurposed two wine tanks and dedicated these to capture and store rainwater. During the wet season over 1,700 kilolitres (kL) or 450,000 gallons (gal) of rainwater was able to be captured and stored for use in the facility’s condensers.

 

Not only does this reduce the amount of groundwater being extracted, but it significantly reduces the chemical treatment needed to soften and descale the water before use.
