Internship – Water and wastewater Performance

"What happens behind the scenes to ensure every drop of water is used responsibly? During this internship, you will explore this topic firsthand and contribute to HEINEKEN's sustainability strategy."

Water is critical for HEINEKEN's beverage production. It is used in our products and our processes. At the same time, environmental standards and our Brew a Better World Strategy require continuous improvement of how water is treated and reused within HEINEKEN.

Across our global brewery network, HEINEKEN operates Water Treatment Plants (WTPs), Wastewater Treatment Plants (WWTPs) and Water Reclamation Plants (WRPs). These facilities play a crucial role in reducing environmental impact, ensuring compliance, and supporting our Brew a Better World Strategy.

During this internship, you will support a variety of projects related to water and wastewater management across HEINEKEN. You will investigate operational challenges, engage with international stakeholders and contribute to improvement initiatives with global impact.

This is a unique opportunity to combine sustainability, innovation and technical problem-solving while contributing to challenges that have a real impact on breweries worldwide.

Interested in making a difference? Join us to help improve our water treatment processes.

In this internship, you will have the opportunity to:

• Explore how water and wastewater treatment systems perform across HEINEKEN's global brewery network
• Work with colleagues from different countries to understand challenges, share best practices, and identify opportunities for improvement
• Analyse data and turn insights into practical recommendations that can create real value for our operations
• Help develop tools, guidance, and visualisations that support decision-making and performance improvement
• Gain hands-on experience at the intersection of engineering, operations, sustainability, and innovation.

During your internship, you will get the opportunity to get to know HEINEKEN as a company, also outside your department. We give you trust and freedom, so you can work like a real entrepreneur. We like to bring the outside world inside, and therefore we embrace new, fresh ideas with enthusiasm. Of course, always with the guidance that is right for you.

The Sustainable Production department (part of Global Production, Supply Chain) consists of a multidisciplinary team working on different subjects of sustainability in our operations, including water and energy usage, decarbonisation, wastewater management and reporting. The team is made up of professionals from different countries, with diverse expertise and academic backgrounds. We are all united by one goal: to make our operations more sustainable.

Your mornings will start with a delicious coffee with colleagues before diving into the day. One day you might be investigating why a water or wastewater treatment plant is not performing as expected and another day, you could be comparing water performance across breweries around the world and reaching out to local teams to understand the story behind the numbers. You will also support technical Water reuse challenges and help find practical solutions based on what the data and local teams are telling you. And of course, it's not all about work! There are plenty of intern gatherings and networking events where you can meet other interns, get to know people from across the company and have some fun along the way.
