Case Study – Good for Environment, Good for Business
Set in Woodside on the outskirts of the stunning Adelaide Hills is the state-of-the-art Petaluma winery, the newest edition to the Petaluma vineyards and cellar door.
The winery opened prior to the 2015 vintage after more than a decade of planning and adds to existing vineyards in the Piccadilly Valley, Clare Valley and Coonawarra.
Now part of Accolade Wines, the winery has a maximum grape crush capacity of 2000 tonnes per annum. The winery crushes and process grapes sourced from the site and the other regions to produce white, red and sparkling wines. An in-situ bottling line allows wine stored in tanks and barrels to be bottled and labelled on site, then packaged and stored prior to distribution.
EPA’s Peter Dolan Director Regulation said the facility incorporates cleaner production strategies with best practice waste management methods in its design.
"The purpose built facility minimises the quantity of wastewater generated. The wastewater management system has been designed to produce high quality reclaimed water primarily for the purpose of irrigation re-use on vineyards and other plantings established on the 31 hectare winery site, where they are now reclaiming up to four mega litres of water per year,” Mr Dolan said.
“Petaluma in Woodside is a very well-managed facility with many processes in place to ensure environmental impact is minimised.
“The considered planning to reduce harm on its surrounds while also supporting sustainable practices is demonstrated in its operations,” he said.
Petaluma winemaker Mike Mudge said working from a greenfield site has allowed Petaluma’s wastewater system to be designed with operational simplicity whilst being able to meet all wastewater variations.
“In doing so this has ensured all regulatory requirements and environmental expectations are met,” he said.
“The company also seeks to invest in the natural environment to ensure a sustainable future for winemaking in the three key regions. This includes planting native vegetation off set areas, with an initial budget of $5,000, then an annual maintenance of $2,000 per year,” Mr Mudge said.
Petaluma was for many years a driver in the rehabilitation of Cox Creek which ran past its old winery, and also the previous cellar door at the Bridgewater Mill.
