From the humble cup of tea to the pint of beer, the beverage industry has long played a central role in UK culture. Yet to produce these drinks, a substantial amount of water is required, leading to significant consumption rates. With the growing climate crisis and the need for sustainable practices, how is this industry adapting to reduce its water footprint? In this article, we will explore the best practices for water usage efficiency in the UK beverage manufacturing sector.
Water forms the backbone of the beverage industry. It is not only a primary ingredient in most drinks but it also plays a pivotal role in cleaning, cooling, and various production processes. Therefore, an effective water management system is crucial.

Many companies have turned to advanced water management systems, which monitor and control water usage meticulously. These systems can identify areas of overuse and waste, enabling companies to implement changes and enhance efficiency. For example, Heineken UK has implemented a state-of-the-art water recycling facility at their Tadcaster brewery, reducing their water consumption by 30%.
As well as implementing robust water management systems, beverage manufacturers are exploring innovative techniques to reduce water consumption further. These tactics go beyond merely fixing leaks or upgrading equipment – they involve rethinking entire processes.

Take the case of Diageo, the global drinks giant behind brands such as Guinness and Smirnoff. They've launched a pioneering program to significantly cut down their water usage by using air instead of water to transfer their grain during the brewing process. This not only reduces their water usage but also saves a significant amount of energy, demonstrating that water efficiency often goes hand in hand with other forms of environmental sustainability.
The water footprint of a beverage is not just about the water used in manufacturing; it also includes the water used in the supply chain. Therefore, working with suppliers who prioritize sustainable water practices is another way for beverage companies to improve their water efficiency.
Sustainable supply chains can encompass a wide range of practices, from sourcing ingredients from farms that use water-efficient irrigation methods to working with packaging suppliers who prioritize water efficiency in their processes. Coca-Cola, for example, has committed to sourcing 100% of their agricultural ingredients from sustainable sources by 2020, including suppliers who efficiently manage water.
The concept of a circular economy has gained considerable traction in recent years, and it's easy to see why. This model advocates for the maximum usage and recycling of resources, which is particularly relevant when it comes to water usage in the beverage industry.
Many companies are now seeking ways to reuse their wastewater, whether for cleaning purposes, onsite landscaping, or even returning it to the public water supply. Scottish brewery BrewDog, for example, is now capable of treating its wastewater to a standard clean enough to be released back into the environment, thus reducing their overall water consumption.
While these changes are driven by the need for environmental sustainability, they are also a response to changing consumer demands. More than ever, consumers are aware of the environmental impact of their consumption and are demanding that companies do their part to protect our planet.
This consumer-driven push for sustainability has led many beverage companies to invest in water efficiency measures, not just to meet regulatory requirements, but also to appeal to environmentally-conscious consumers. This trend is expected to continue, with companies that prioritize water conservation likely to gain a competitive advantage in the coming years.
In summary, water usage efficiency has become a pressing issue in the UK beverage industry. By investing in advanced water management systems, exploring innovative techniques, prioritizing sustainable supply chains, and embracing the circular economy, companies can significantly reduce their water footprint. More importantly, these measures are not only beneficial to our planet; they can also contribute to a company's bottom line by attracting sustainably-minded consumers and enhancing overall efficiency.
For the beverage industry, water stewardship goes beyond simply reducing water consumption. It involves taking a holistic approach to water management, focusing on both the quantity and quality of water used. This approach recognises the importance of maintaining clean water supplies for the wider community and future generations.
Water stewardship initiatives can include various strategies, such as sourcing water responsibly, improving water-use efficiency, treating wastewater before it's discharged, and returning clean water to the environment. These practices help to preserve water supplies, reduce pollution, and promote a healthier ecosystem.
For instance, Nestlé Waters UK has set an example by signing up to the Alliance for Water Stewardship (AWS) Standard – a globally-recognised framework for sustainable water use. By implementing the Standard’s principles, Nestlé has managed to reduce water waste and improve the quality of water returned to the environment.
One area where the beverage industry can make considerable water savings is by reducing food waste. Whether it’s wasted ingredients, unsold products, or by-products from the production process, food waste can significantly increase a company's water footprint.
In addition to representing a waste of water, wasted food also means wasted energy, labour, and other resources that have gone into producing it. Thus, reducing food waste can have a multiplier effect on resource conservation, including water saving.
Beverage manufacturers are developing various strategies to reduce food waste, from improving inventory management to finding innovative uses for by-products. For example, British brewer Toast Ale makes its beer using surplus bread that would otherwise be wasted, thereby reducing both food waste and water usage.
As we have seen, the UK beverage industry has a significant role to play in promoting water efficiency and tackling climate change. From installing advanced water management systems to adopting innovative techniques, companies are finding multiple ways to reduce their water consumption and enhance their water stewardship.
However, it's not just about what happens within the four walls of a brewery or factory. Embracing sustainable supply chains and committing to the principles of a circular economy can have far-reaching impacts, extending water savings beyond the manufacturing process.
Moreover, these measures are increasingly recognised by consumers. As awareness of environmental issues grows, so does demand for sustainably-produced beverages. With consumers willing to vote with their wallets, companies that prioritise water efficiency are likely to see not just environmental benefits, but economic ones too.
In conclusion, water usage efficiency is not a trend, but a necessity for the UK beverage industry. By continuing to invest in water-saving measures, the sector can contribute to a more sustainable future, satisfying not only the needs of the planet but also those of consumers and businesses.
