Aalto University Water and Environmental Engineering Master’s Thesis Guide: 30 ECTS ENG Process, Research Proposal and Evaluation

Aalto University’s Master’s Programme in Water and Environmental Engineering (WAT) is a 120 ECTS Master of Science (Technology) programme organised by the School of Engineering. Under the current 2026–2028 curriculum, the degree consists of 60 ECTS major studies + 30 ECTS master’s thesis + 30 ECTS elective studies.

The current major code is ENG29. The thesis itself is BE.thes, 30 ECTS, and the separate ENG.matr maturity test is 0 ECTS. Aalto recommends devoting the spring semester of the second study year to the thesis while beginning topic planning earlier.

For WAT students, the subject can vary widely, but the administrative route is one common School of Engineering process. The current programme describes three complementary study paths around water resources and environmental hydraulics, water and wastewater engineering, and water and development. Those paths shape the question, evidence and methods of a thesis. They do not create three different thesis procedures.

The controlling rules are straightforward:

• the assessed written thesis is individual;
• 30 ECTS corresponds to a School of Engineering planning baseline of roughly six months of full-time work / about 800 hours;
• the thesis has an eligible Aalto supervisor and may have one or two advisors;
• topic and supervision information are formalised in MyStudies;
• the ENG process includes a research proposal;
• the finished thesis must be presented before approval;
• the thesis abstract serves as the maturity essay;
• the final examined thesis is submitted as PDF/A through MyStudies;
• evaluation uses the 0–5 scale; and
• the Degree Programme Committee makes the formal approval and grading decision.

Aalto also maintains detailed operational instructions in an authenticated ENG Master’s Thesis Guide in MyCourses. This article uses current public programme and School of Engineering sources and does not reconstruct hidden forms or internal model schedules.

Where the thesis fits in the current WAT degree

The 2026–2028 WAT structure gives students a broad technical foundation before the thesis. The 60 ECTS major contains 12 ECTS of compulsory studies and 48 ECTS chosen from the programme’s current advanced course offering. The compulsory WAT-E1001 Water and Environment Engineering course is 12 ECTS.

The advanced course list lets students build different expert profiles. Depending on the study plan, a student may deepen work in hydrology, groundwater, surface-water resources, environmental hydraulics, water governance, sustainable built environments, physical and chemical treatment, wastewater networks, biological treatment, process modelling, circularity or related topics.

The applicant-facing programme describes three broad study paths. They are useful for thinking about thesis direction, but they are not separate majors with separate thesis approval systems. One student may study flood risk or hydrological modelling, another may work on water-treatment performance, and another may investigate governance, infrastructure, water security or development questions. All still use the same BE.thes / ENG thesis framework.

That distinction matters because the research design should follow the actual question, while the administrative process remains common.

Start topic planning before the second-year spring

Aalto recommends the spring term of the second year for the thesis. At the same time, the curriculum and recommended timetable encourage students to start topic planning earlier.

This is sensible for WAT because many projects depend on evidence that cannot be arranged instantly. Field measurements may be seasonal. Laboratory work may require equipment bookings and sample preparation. Utility or municipal datasets may require access agreements. A modelling project may depend on calibration data. Interviews or stakeholder research may require ethics, recruitment and scheduling work.

There are two normal routes into a topic. Programme professors may offer topics linked to current research, and students may also propose their own topic to a potential supervisor. In either case, the topic should be connected to the programme’s advanced studies and fit the expertise of the intended supervisor.

Before formalising a topic, test four things:

1. Researchability: can the practical water or environmental problem be turned into a clear academic question?
2. Evidence: are the required measurements, datasets, samples, documents or participants realistically available?
3. Method fit: can the proposed method actually answer the question?
4. Scope: can the work be completed at a 30 ECTS scale within the agreed schedule?

Early narrowing is often more valuable than making a broad topic sound ambitious.

The three study paths do not create separate thesis rules

WAT’s breadth can make students wonder whether different specialisations have different administrative thesis requirements. Current public sources do not support that interpretation.

The current curriculum has one ENG29 major, one 30 ECTS BE.thes, and one 0 ECTS ENG.matr maturity test. There is no separate compulsory thesis-seminar ECTS course listed in addition to the thesis.

The study paths should instead be used as intellectual orientation. For example:

• a water-resources or environmental-hydraulics project may rely on field data, hydrological models, flow analysis or spatial/temporal datasets;
• a water and wastewater engineering project may use laboratory experiments, treatment-process modelling, network analysis, process data or design calculations;
• a water-and-development or governance-oriented project may combine quantitative evidence with policy analysis, interviews, institutional analysis or mixed methods.

These are examples, not mandatory templates. Do not copy an SPT thesis seminar, a Real Estate Economics video-presentation format or another programme’s course code simply because all of them belong to the School of Engineering.

Choose the supervisor and advisor structure correctly

Under current School of Engineering policy, thesis supervision can be provided by professors and certain other authorised academic staff, including adjunct professors, professors of practice, senior university lecturers and principal university lecturers.

The thesis may have one or two advisors. An advisor must hold at least a master’s degree. The advisor may be an Aalto researcher, doctoral researcher, university teacher, company specialist, consultant, municipal expert, utility professional or another person with relevant expertise.

The roles are different. The supervisor carries the university’s academic responsibility for the thesis and must ensure that the work meets School of Engineering expectations. An advisor may provide more frequent technical, empirical, organisational or domain-specific guidance.

For a thesis connected to an external organisation, a practical arrangement is often an authorised Aalto supervisor plus an external advisor who knows the data, system or project context. External involvement does not replace the academic supervisor.

The written thesis must be individual

School of Engineering policy states that master’s theses cannot be written as pair or group written theses. The assessed written thesis is individual work.

This does not prevent students from working in the same research group, using related datasets or contributing to a broader municipal, utility, laboratory or company project. It means each student needs an independently defensible research problem, contribution, analysis and written report.

In WAT this boundary is especially relevant in team-based research environments. Two students may work around the same water system or treatment process, but each thesis must make clear what that student investigated, which evidence was analysed, which conclusions are justified, and how the work remains independently assessable.

Formalise the topic and supervision in MyStudies

The formal School of Engineering thesis process uses MyStudies. Before completing the topic step, the student should already have agreed the topic with the intended supervisor and advisor or advisors.

The MyStudies thesis record contains the core thesis information, including topic, supervisor, advisor arrangements and thesis language. The record then connects to later submission, evaluation and archiving.

The ENG guideline also expects the student’s degree structure and study plan to be in order at the thesis stage. WAT is designed so that major studies are largely completed during the first year, and this is one reason the second-year thesis can be approached with the necessary subject knowledge.

Do not leave formal topic and supervision details until the final month. An accurate MyStudies record is part of the thesis process, not merely an upload box at the end.

Build the research proposal before full execution

The School of Engineering thesis workflow includes a research proposal. This is where a broad interest becomes a manageable research project.

The proposal should define, as relevant:

• the background and theoretical or technical framework;
• the research problem and research questions;
• the main objective and possible intermediate objectives;
• the evidence or empirical material;
• the research or design methods;
• the timetable; and
• important practical constraints, including budget where relevant.

For WAT, feasibility questions can be concrete. If field measurements are essential, what is the measurement window? If a treatment experiment is planned, what equipment and samples are needed? If the thesis uses utility data, who controls access and in what format? If a model is used, what calibration and validation evidence is available? If interviews are planned, who are the participants and how will they be recruited?

A strong proposal makes these dependencies visible before the project becomes difficult to change.

Treat six months and about 800 hours as a scope constraint

The School of Engineering treats a 30 ECTS thesis as approximately six months of full-time study. Its thesis guidance also uses roughly 800 hours as the overall workload planning baseline.

These numbers are not a stopwatch. They are a scope-control tool. A thesis should be demanding enough to demonstrate master’s-level competence without becoming an open-ended research programme.

For WAT, scope creep can happen in several ways: collecting too many field variables, expanding a model to several catchments, trying to test too many treatment conditions, adding several stakeholder groups, or turning one research question into a consultancy project with many deliverables.

The student, supervisor and advisor should agree a realistic schedule and adjust the research design if access or data problems appear. ENG evaluation guidance also allows schedule performance to be considered in assessment, while delays outside the student’s control are treated as extenuating circumstances.

The practical lesson is to define a credible stopping point before the project starts.

Match the method to the water or environmental question

WAT does not prescribe one universal thesis method. Method choice should be driven by the question and available evidence.

A hydrology project might use time-series analysis, watershed modelling, remote sensing or field measurements. Environmental hydraulics may rely on laboratory or numerical flow analysis. Water-treatment research may use bench-scale experiments, process measurements, chemical or biological analysis, or process modelling. Network research may use hydraulic modelling and system data. Governance or water-and-development research may use policy analysis, interviews, surveys, institutional data or mixed methods.

The important issue is alignment:

• the question determines the evidence needed;
• the evidence must be suitable for the method;
• the method must generate results capable of answering the question; and
• conclusions must stay within what the evidence supports.

A method used successfully in an earlier Aalto thesis is not automatically appropriate for a new project. Use previous theses as orientation, not as a substitute for research design.

Company, utility and commissioned theses remain academic and public

WAT research has direct connections to consulting, utilities, municipalities, public agencies, research organisations and industry. A commissioned thesis can therefore be a strong route into a relevant problem.

An external partner may provide data, samples, sites, technical systems, expert knowledge or a practical challenge. The thesis still remains an Aalto academic work and must satisfy ENG evaluation criteria.

The evaluated master’s thesis is also a public document. Confidential partner information, security-sensitive infrastructure information, personal data or commercial secrets cannot simply be placed into the evaluated thesis and then made non-public by agreement.

Set the confidentiality boundary before data collection. Sensitive supporting material may have to remain outside the assessed thesis, while the public document contains the research problem, permissible evidence, method, analysis and conclusions.

Choosing not to make the full text immediately downloadable in Aaltodoc does not make the approved thesis confidential.

Use literature, Turnitin and AI responsibly

A WAT thesis should be built on relevant scientific and professional literature. Depending on the topic, this may include peer-reviewed water research, engineering standards, modelling literature, technical reports, policy documents or other defensible sources.

Turnitin can support source-use and originality checking. A similarity percentage is not itself a plagiarism verdict. Correct quotations, references and common technical language can contribute to similarity, so the report must be interpreted in context.

The student remains responsible for citation, paraphrasing, data integrity, calculations, model choices and final accuracy.

AI use must follow current Aalto and thesis-specific rules. Do not place confidential research data, personal information or restricted project material into unapproved public AI services. Most importantly, language models are not permitted in the maturity test under current Aalto guidance.

Complete the thesis presentation before approval

The current WAT curriculum and thesis page state that the 30 ECTS thesis entity includes a presentation. The School of Engineering guideline describes this as presentation of the finished thesis at a time agreed with the supervisor.

The presentation, or equivalent programme event used to showcase the finished thesis, must occur no later than the final day on which the student applies for thesis approval.

The public WAT pages do not currently publish a fixed programme-wide presentation calendar, mandatory slide count or universal presentation duration. Do not import the 5–10 minute video rule used in Real Estate Economics or the 15+15 minute SPT seminar format.

Agree the current presentation arrangement with the supervisor and check the authenticated ENG MyCourses guidance when planning the final weeks.

The abstract serves as the maturity essay

At the School of Engineering, the thesis abstract serves as the maturity essay. The supervisor checks whether the abstract demonstrates knowledge of the thesis topic and field.

Depending on the student’s earlier education and whether Finnish or Swedish proficiency has already been demonstrated, a language check may also be required. The ENG guideline advises reserving roughly 14 days for a required Language Centre check.

The maturity essay is assessed separately on a pass/fail basis. Because the thesis abstract is the assessed maturity component, the current Aalto restriction on language-model use applies directly to that component.

Students should therefore finalise the abstract as an academic requirement, not treat it as an afterthought generated at submission time.

Submit the final thesis through MyStudies as PDF/A

The final School of Engineering thesis is submitted electronically through MyStudies. The current ENG guideline requires the examined thesis file to be PDF/A.

Before final submission, the thesis should already be in its examined form. Topic and supervision should be approved, the presentation should be complete, the maturity abstract should be ready, and the supervisor should have had enough time to review the manuscript.

Approved theses are transferred to Aaltodoc for archiving. Full-text online publication consent is separate from the legal and academic status of the approved thesis as a public document.

Validate the PDF/A file before the deadline rather than discovering format problems during the final upload.

Understand how the thesis is graded

School of Engineering master’s theses use the 0–5 scale:

• 0 = fail;
• 1 = passable;
• 2 = satisfactory;
• 3 = good;
• 4 = very good; and
• 5 = excellent.

The supervisor submits a written evaluation statement and proposed grade. The Degree Programme Committee makes the formal approval and grading decision.

Evaluation is broader than whether the technical result appears useful. Current ENG criteria consider the research problem, scope and goals, command of relevant theory and sources, appropriateness of methods and empirical material, analysis and conclusions, structure and presentation, and the student’s independent project performance.

For proposed grades 1, 5 or fail, the ENG guideline requires an additional independent academic consultation or second-examiner step. A thesis submitted for evaluation is normally expected to be evaluated within four weeks.

Allow time for supervisor review before the administrative deadline

The final deadline should not be the date on which the supervisor first sees a complete manuscript.

Work backwards from the intended evaluation deadline and reserve time for:

1. a complete manuscript;
2. supervisor and advisor feedback;
3. corrections;
4. presentation of the finished thesis;
5. maturity-abstract completion and any language check;
6. PDF/A validation; and
7. the MyStudies evaluation application.

Experimental and field-based WAT projects need an extra buffer because the analysis stage may expose missing measurements, failed experiments or model problems. The earlier the student and supervisor identify these issues, the easier it is to protect the submission plan.

Current programme-specific thesis deadlines

As verified on 30 August 2026, the remaining WAT thesis-evaluation deadlines publicly listed for 2026 are:

• 28 September 2026 -> Degree Programme Committee 19 October 2026;
• 23 November 2026 -> committee 14 December 2026; and
• 31 December 2026 -> committee January 2027.

The WAT graduation page also contains graduation-only dates where there is no committee meeting. For such a date, the thesis and maturity test must already have been approved and registered.

The current WAT programme pages do not yet publish a complete programme-specific 2027 thesis-evaluation calendar. This guide therefore does not borrow 2027 dates from another School of Engineering programme or from a general calendar and label them as WAT committee deadlines.

If you are planning a 2027 thesis approval, recheck the live WAT Thesis and Graduation pages and the authenticated ENG Master’s Thesis Guide before fixing the submission date.

A practical WAT thesis workflow

A defensible sequence is:

1. Review the HOPS and first-year progress. Make sure the major foundation is strong enough for the intended topic.
2. Explore the WAT study paths and research groups. Use them to identify a problem area, not to invent separate thesis rules.
3. Start topic discussions early. Consider Aalto research topics and external water-sector projects before second-year spring.
4. Agree an eligible supervisor and advisor structure. Clarify who has academic responsibility and who provides day-to-day expertise.
5. Formalise topic and supervision in MyStudies. Keep the thesis record accurate.
6. Prepare the research proposal. Lock the question, evidence, method, scope and schedule.
7. Execute a six-month-scale project. Protect the 30 ECTS boundary and document material changes.
8. Use supervision actively. Raise data, laboratory, modelling or access problems early.
9. Deliver a complete manuscript with review time left. Do not wait for the administrative deadline.
10. Complete the finished-thesis presentation. Use the current WAT/ENG arrangement agreed with the supervisor.
11. Finalise the maturity abstract. Respect language requirements and the language-model prohibition.
12. Validate PDF/A and submit through MyStudies. Recheck the live deadline.
13. Allow for Degree Programme Committee approval. Submission and formal approval are separate stages.
14. Request graduation in Sisu when degree requirements are ready. Keep the study plan approved and attendance status valid.

Final checklist

Before final submission, confirm that:

• your thesis is the current 30 ECTS BE.thes project under ENG29;
• ENG.matr is the separate 0 ECTS maturity requirement;
• you have not added an invented WAT thesis-seminar credit value;
• the written thesis is individual;
• the supervisor is eligible under current ENG rules;
• any advisor has at least a master’s degree;
• topic and supervision information are approved in MyStudies;
• the research proposal defines a feasible question, evidence base, method and schedule;
• the project remains realistic around the six-month / ~800-hour ENG baseline;
• the chosen method fits the actual water or environmental question;
• confidential partner or personal information is outside the evaluated public thesis where required;
• citations, Turnitin and academic-integrity issues have been resolved;
• the finished-thesis presentation is complete;
• the abstract satisfies the maturity requirement and no prohibited language-model assistance was used;
• the final examined file is valid PDF/A;
• the current WAT thesis/graduation deadline has been rechecked; and
• no presentation rule or 2027 deadline has been imported from another programme.

The most reliable planning principle is simple: treat Water and Environmental Engineering as a broad research context inside one common School of Engineering thesis process. The thesis question may involve hydrology, hydraulics, treatment, networks, governance, sustainability or development, but successful completion still depends on a researchable problem, feasible evidence, an agreed schedule, active supervision and disciplined completion of the ENG approval steps.
