Description
Ensuring sustainable use of natural resources under changing climate is our planet’s biggest challenge. Water resources management plays a critical role in guaranteeing food security and is closely linked to land use changes, nutrient flows, and biodiversity conservation. Further, climate change is expected to bring more extreme droughts and floods – both to which societies need to adapt.
Creating functional and sustainable water supply networks is among the most vital tasks in our society. The goal is not only to guarantee clean water supply and to protect the environment from the load of wastewater at all times, but also to reduce the environmental impact through a circular economy recovering nutrients and energy.
In the Water and Environmental Engineering (WAT) Master’s Programme, the focus is on water and water engineering solutions. Students learn the knowledge and skills to provide solutions to modern water-related challenges. The programme has a unique international focus and it combines a strong technical basis with a sound understanding of broader societal contexts.
Upon graduation, you are able to:
- Recognise and analyse the main components of sustainable water-related planning, implementation, and management processes.
- Understand the principles of the hydrological cycle and movements of water in natural and built environments.
- Apply key computational methods as well as relevant experimental methods and data analysis approaches related to water and environmental engineering.
- Design and develop urban water and wastewater systems to support sustainability and circular economy.
- Identify the societal context relevant to water and the environment, and comprehend the different scales and key drivers applicable to water and environmental engineering.
Language of instruction
In this master’s programme, the language of instruction is English.

Structure of studies
Water and Environmental Engineering Master’s Programme consists of 120 credits (ECTS):
- Major studies (60 ECTS)
- Elective studies (30 ECTS)
- Master’s thesis (30 ECTS)
Students are able to complete their common and advanced studies during the first year. This leaves your second year for elective courses and the Master's thesis. You can choose practically any combination of elective courses – from Aalto as well as other universities in Finland and abroad – that supports your studies and suits your interests, including courses focusing specifically on environmental engineering. This study structure also makes it easy for you to go on a student exchange during the second year.
Our teaching combines theory with practice, including hands-on modelling work, case studies, group works, and projects. Many of our courses also collaborate with the industry and other stakeholders in the form of project works, mentoring and guest lectures.
More information about the programme content and curriculum can be found in the Student guide.

Specialisations
In this programme, students can tailor their studies to best suit their interests and aspirations. There are three study paths that complement each other through their own thematic and methodological focuses. The study paths enable you to build your own expert profile, and you will take courses from at least two different study paths: this also helps you to gain a broad understanding of our field. The study paths are:
1. Water Resources Management and Environmental Hydraulics
In this path, the focus is on varying topics related to water resources management, hydrology and environmental hydraulics:
- Surface water, groundwater, and runoff management
- Urban water and stromwater management
- Sustainable use of water in cities, agriculture, and forests
- Ecohydraulics, computational hydrology, and hydraulics applications
- Measurement of changes in water and the water environment caused by anthropogenic activities
2. Water and Wastewater Engineering
This study path deals with the water services that are crucial for society – these services need to function every day and under all circumstances. Sustainable water services protect human health and the environment. They are the premise for development. The main topics include:
- Clean water production and sanitation
- Environmental protection through wastewater treatment processes
- Circular economy as well as resource recovery from wastewater and sludge
- Climate impact mitigation in water services
- Modelling and optimization of water treatment processes and water service systems
3. Water and Development
Water is at the core of sustainable development at both local and global scale. This study path considers the diverse linkages between water and development across scales, and students learn about, among other things:
- Global water challenges with a multidisciplinary problem-solving approach
- The impact of climate change on water
- Use of water and other key natural resources in food production
- Water governance and water resources management, including transboundary water cooperation
- Sustainability and sustainable global technologies
Internationalisation
Many of the courses in this programme have an international focus. One of them (SGT Studio) offers you a possibility to carry out an international student project in different parts of the world as a part of multidisciplinary student team. Recent SGT project locations have included, e.g., Mexico, Uganda, Kenya, Tanzania, and Nepal.
The WAT Master’s Programme collaborates with various international universities, and students have the chance to complete part of their degrees abroad as exchange students. The programme also cooperates with Aalto Global Impact that facilitates global sustainability projects in collaboration with research teams and Master’s programmes. Many of the research topics at the Department of Built Environment are global.
Overall, Aalto University is known for its international study and research environment. Every year, Aalto welcomes thousands of degree and exchange students from abroad. Additionally, many of our professors and researchers have international backgrounds and experience, bringing their networks close to students.
Further study opportunities
The WAT Master’s Programme is considered a great foundation for doctoral studies. At Aalto, doctoral education is actively being developed by the Water and Environmental Engineering research group through experiences gained from the Majakka project. The research group provides doctoral students with an inspiring research environment to carry out their studies.

Career opportunities
Water and environmental engineering provides you with diverse career opportunities. There is a consistent demand for experts in this field with good advancement opportunities during their careers. While most of our graduates work in Finland, our Master's programme prepares you also for an international career for example within the United Nation system.
Our graduates typically work in the fields of water resources management and water engineering as planners, technical experts, and managers. They have varying tasks related to, for instance, water supply planning as well as environmental and flood risk management. The typical employers include consulting firms, regional environmental centers, cities and municipalities, research institutes such as Finnish Environment Institute Syke, equipment and process suppliers as well as water utilities. Part of our graduates continue to our doctoral studies.

Research focus
The main research themes of the Water and Environmental Engineering Research Group are the same as the study paths of WAT Master’s Programme: Water Resources Management and Environmental Hydraulics, Water and Wastewater Engineering as well as Water and Development. You can find more information about these research topics here.
Co-operation with other parties
Water and Environmental Engineering Master's Programme collaborates closely with the industry, engaging both public and private sector actors in education. This means guest lectures and joint projects that provide you with a view on and connections to the working life. In addition, the programme cooperates with other programmes at Aalto.
