Instructions to Authors

The Journal of Water and Environment Technology (JWET) welcomes submissions from all authors, regardless of location or background. Articles can span local, regional or global scales, but must be placed into a context that ensures relevance and interest to our global audience. JWET is committed to an ethical, fair and rapid peer-review process.
The Journal of Water and Environment Technology is an Open Access, fully peer-reviewed international journal for all aspects of the science, technology and management of water and the environment. The journal’s articles are clearly placed in a broader context to be relevant and interesting to our global audience of researchers, engineers, water technologists, and policy makers.
JWET is the official journal of the Japan Society on Water Environment (JSWE) published in English, and welcomes submissions that take basic, applied or modeling approaches to the interesting issues facing the field. Topics can include, but are not limited to: water environment, soil and groundwater, drinking water, biological treatment, physicochemical treatment, sludge and solid waste, toxicity, public health and risk assessment, test and analytical methods, environmental education and other issues. JWET also welcomes seminal studies that help lay the foundations for future research in the field.
JWET is committed to an ethical, fair and rapid peer-review process. It is published six times per year. It has two article types: Original Articles and Review Articles.
Authors should carefully read the journal policies below as submission to the journal implies that all authors have read and approved them. Further details about the journal’s ethical processes are available in the document: ‘Ethical Provisions for the Journals of the Japan Society on Water Environment’, available at
Submission to the journal also implies that all authors have seen and approved of the manuscript, have agreed to its submission, have the right to publish the work and that it is not libellous or defamatory. All authors also undertake that the manuscript is an original work that has not been previously published in any language, nor is under consideration elsewhere. Authors must inform the editors if any related publications are under consideration or in press elsewhere.
Contributors to JWET should meet the following criteria for authorship. They must have:
  • -made a substantial contribution to the conception or design of the work, or the acquisition, analysis or interpretation of data for the work;
  • -drafted the manuscript or revised it critically for important intellectual content;
  • -approved the final version of the manuscript for publication; and
  • -agreed to be held accountable for all aspects of the work.
  • Submission to the journal implies that all authors have agreed to the author list and the order of it. Any amendments to the list (such as changing the order, or adding or removing authors) after submission must be approved by all authors and the editor.
    Unoriginal material
    Authors undertake that their submissions to the journal are original works. The journal uses the iThenticate software to screen material and authors agree to this process upon each submission. The journal reserves the right to return material that is found to contain and unacceptably amount of unoriginal material.
    Image integrity
    Community standards must be met in the presentation of images. While digital manipulation or processing of images is allowed, all figures must accurately reflect the underlying data. The editors reserve the right to request original data and images from the authors.
    Reproducing copyrighted material, including maps
    Manuscripts that contain figures, maps or other previously published material that is subject to copyright must obtain permission from the copyright holder and provide this evidence upon submission.
    Availability of data and materials
    The journal supports the use of Supplementary Material for data and relevant materials, or the use of relevant and accepted public repositories and databases. See the Supplementary Materials section for further details on the format and style for these materials.
    If data has been used from repositories or databases, relevant identifiers or details must be included in the submission.
    Animal/human experimentation
    In submissions dealing with human experimentation or materials derived from humans, the authors must demonstrate that the work was undertaken in accordance with the Declaration of Helsinki and its revisions, and any guidelines approved by the authors’ institutions. For experiments conducted using animals or materials derived from animals, the authors must demonstrate approval for the work under the authors’ institutional guidelines.
    A statement must be included in either the Materials and Methods section or a separated section after the Acknowledgements.
    Conflicts of interest
    The journal maintains strong policies for conflicts of interest among editors, reviewers, editorial board members and staff, and authors. Further, all authors must declare any conflicts of interest and this text must be explicitly included upon submission of their manuscript. In addition, authors should list all funding sources for their work in the Acknowledgments section, including grant numbers where possible.
    All manuscripts that are under consideration, or have been rejected, are kept in-confidence. Authors agree to keep all correspondence from editors and the editorial office about their submission confidential.
    The journal undertakes single-blind peer review and as such all reviewers’ identities are not disclosed, unless explicitly requested by the reviewer. As part of their agreement to review articles for the journal, reviewers agree to maintain the confidentiality of submitted manuscripts.
    Editorial and peer review process
    The Section Editors allocate submitted manuscripts to an Associate Editor, who oversees the peer review process. The Associate Editor invites at least two reviewers to provide an assessment of the submission; reviewers are selected based on their knowledge, reputation and experience as peer reviewers. When the reviews have been received, the Associate Editor assesses the manuscripts, review reports and makes a first decision.
    If a manuscript does not meet the journal’s requirements for acceptance, but has a high probability of acceptance after minor or major revision, the Associate Editor may ask the authors to revise it accordingly. Revised manuscripts must attend to the points raised by the reviewers and the Associate Editor and be re-submitted within one month for minor revision and within two months for major revision; otherwise they will be treated as new submissions. Revised manuscripts may be sent back to the original or new referees, as determined by the Associate Editor.
    After revision and re-assessment, if the manuscript satisfies the journal’s requirements and represents an original contribution to the published literature, the Associate Editor may accept the manuscript for publication in the journal.
    If a manuscript does not meet the journal’s requirements for acceptance, the Associate Editor may decide to return the manuscript to the authors.
    Other members of the Editorial Board act in advisory roles, act as reviewers and make suggestions to improve JWET. The co-Editors-in-Chief act as arbiters as required.
    Reviewer suggestions
    Authors can suggest potential reviewers who would be suitable to review their manuscript. Those suggested should be qualified and knowledgeable to provide valuable advice.
    Authors must declare any current or former relationships with those suggested. Potential reviewers that the authors wish to be excluded can also be nominated. The journal may consider these requests but is under no obligation to grant them; the Editors maintain complete discretion for the selection of reviewers.
    The journal will consider appeals that provide specific evidence of misunderstanding, mistake or error by a reviewer or editor. Appeals are considered by the co-Editors-in-Chief whose decision is final.
    Errata and retractions
    The journal supports the maintenance of a complete record of science and hence the correction of any significant errors in the journal. If authors discover a significant error or inaccuracy in their published article, they are obligated to promptly notify the co-Editors-in-Chief and cooperate with their instructions. The co-Editors-in-Chief will also assess any third-party advice received and, in both cases, determine whether an Erratum or a Retraction is appropriate.
    Errata describe errors that significantly affect the scientific integrity of a publication, or the reputation the journal or authors. Retractions are used when the results or conclusions are found to be invalid or misleading, or when there is sufficient evidence of research or publication ethics breaches. Minor errors that are the result of the authors’ actions will not be addressed.
    If co-authors do not agree to a correction being published, the journal reserves the right to proceed with publication of an Erratum or Retraction that lists the dissenting co-authors.
    JWET recently moved to a fully Open Access publication model. For more information on the journal’s Open Access policies, see the Open Access Frequently Asked Questions (FAQs) available at
    http://www.jswe.or.jp/eng/publications/instructions/OA_FAQs.html.(in preparation)

    English standard
    Manuscripts should be written in comprehensive, grammatically correct English. Authors are strongly encouraged to have their manuscript checked by a native English speaker or by an editing service prior to submission. A manuscript withpoor English quality may be rejected without undergoing peer review.
    Style and Format
    A template for submissions is available from http://www.jswe.or.jp/eng/publications/instructions/index.html. Microsoft Word is recommended to be used for preparing manuscripts although the journal can process most of the popular word-processing packages. To avoid compatibility and readability issues, authors should not change the style, add their own macros, include the revision history, or leave any comments in the final submitted file.
    Submissions should be single-spaced and include page numbers throughout. Please use Times New Roman 11pt, except for the title, which should be 14pt. Do not use the symbol font. Currency symbols such as $, €, ₤, and ¥ should be avoided: use USD, EUR, GBP, JPY etc. instead.
    The first page of each manuscript should contain: Title, Authors’ full names, Affiliations, Keywords, and the name, address, telephone number and e-mail address of the corresponding author.
    Define abbreviations upon first appearance in the main text (except in the Abstract). The use of abbreviations should be minimized, especially in the Abstract.
    The Title should be specific, descriptive, and intelligible to readers outside the specific field. Specialist abbreviations should not be included in the title. The title should be formatted in proper (i.e. sentence) case.
    Authors / Corresponding author
    Include the full names of all authors and format in proper (i.e. sentence) case. Note that the last name listed is most often used as the family name in most databases.
    The affiliation includes department, university, or organizational affiliation and the name of the city and country of location. When authors belong to different institutions, their respective addresses should be indicated by superscript alphabets.
    The Abstract is vital to attracting interest to your work and should present a compelling and cogent overview of your work that is accessible to a broader audience. In a maximum of 200 words, it should describe the main objective(s) of the study, a brief methodology and the most important results and their significance. Please do not cite references in the Abstract.
    A maximum of 5 keywords should be given so that information retrieval systems can better locate your article. Avoid including words already in the title.
    The Introduction should describe the context and background of the work to ensure that it is accessible, relevant and of interest to all the journal’s readers. It should also ensure that the significance of your work can be fully grasped. It should allow readers, both inside and outside the specific field, to understand the purpose and significance of the study.
    The problem(s) being addressed should be clearly defined and a brief review of the key literature may be included. It should conclude with a brief statement of overall aim(s) of the work.
    Materials and Methods
    The Materials and Methods section should include the design of the study, the type of materials involved, a clear description of all comparisons, and analyses used, to enable replication by skilled researchers. If materials, methods, and protocols are well established, authors may cite articles where those protocols are described in detail.
    The name of manufacturer should be accompanied with information of its location (city and country) unless it is commonly recognized by international readers. For field studies, the study site should be described so that readers who are not familiar with the site can fully understand issues relevant to the site.
    Results and Discussion
    The Results and Discussion section should adequately detail the results of the manuscript’s experiments and outline the outcomes of the relevant analyses.
    Interpretations drawn from the results should be provided and these used to support the conclusions of the paper. The Results and Discussion may be combined into one section or presented separately.
    The Conclusions section should describe briefly the significance and the implications of the work reported. An itemized style using bullet points is acceptable.
    The Acknowledgements section should include anyone who contributed substantially to the paper but does not meet the criteria for authorship. The funding sources (including grant numbers) should also be included.
    All work cited in the text should be included in the References section. References must always be given in enough detail for the reader to locate the work cited.
    The journal uses a modified Vancouver format for the references in the body of the manuscript and the References section. That is, each reference should be numbered in the order that they appear in the text as such: e.g. [1], [2], [3], ... . If the multiple sources are cited at the same time, the following style should be used e.g. [1, 4, 7–10]. Each numbered reference must then be listed in the References sections in order.
    If a reference was published in a non-English language such as in References [3], [5] and [6] below, the title should be translated into English and the original language should be provided in the manner shown below. If allowable under the relevant copyright provisions, we encourage the authors to provide the reference information in their original language(s) in Supplementary Materials to help readers identify the original reference.

    Unpublished data and personal communications
    Cite unpublished data only in the main text, in such a way as “The trend was confirmed by additional experiment (unpublished data)” Citation of unpublished data and personal communications should be avoided as far as possible.
    Tables should be provided on separate page(s) after the main text (see the template file for examples). Tables must be numbered with Arabic numerals, followed by a brief title and numbered as e.g. Table XX (where XX = 1, 2, ...), both in the table title and in the main text where the table is cited. We recommend using the ‘Tables’ feature in Microsoft Word to create tables. Do not paste tables as pictures. Footnotes should be placed directly after the table.
    Figures should be provided on separate page(s) after the Tables section (see the template file for more details). Figure should be numbered as e.g. Fig. XX (XX = 1, 2, ...) in the figure legends. In the main text or elsewhere, figures should be cited as Fig. XX, but if it appears in the head of a sentence, it should not be abbreviated (it should appear as Figure XX).
    Note that Figures should be clear and informative. Authors should have in mind that Figures may be re-sized to fit into the journal’s two-column format and may therefore be smaller than that submitted and intricate details can be lost.
    The relevant copyright provisions must be adhered to and permissions sought, provided and attributed, for any materials (especially maps) that is not fully owned by the authors. We encourage the use of maps where and when relevant, and we encourage authors to re-draw maps where possible.
    Supplementary materials
    Supplementary Materials should be provided as a single PDF or MS Word file. The figures and tables in Supplementary Materials should be numbered as e.g. Fig. S1, S2, ... and Table S1, S2, . Authors can include the reference information in the original language, if the reference has been published in the language other than English and copyright issues are addressed. Note that when accepted for publication, the authors will be requested to convert the file into a pdf file with its size less than 50MB.
    See the template files for the way how to mention Supplementary Materials in the main text (JWET_template) and the format of the contents of a Supplementary Materials file (JWET_template_SM) at http://www.jswe.or.jp/eng/publications/instructions/index.html.
    Nomenclature and units
    The terminology and notation used in manuscripts must be widely accepted and understood by the water science and technology research community. SI units are strongly recommended. When non-SI units are used, SI equivalents (or conversion factors) must also be given. The symbol for liter should be 'L', not 'l'. Specify the unit carefully so that ambiguity is avoided. For example, the use of 'kg-dry' or 'kg-wet' may be more suitable rather than 'kg' only. We accept both expression styles, mg/L and mg L–1 but the style should be consistent within a manuscript.
    MathType is the preferable software to prepare equations and related terms. Simple equations can be prepared using the built-in function of Microsoft Word. Tex format should be avoided.
    Equations should be numbered with Arabic numbers and the equation numbers should appear right after each equation as (XX) In the main text or elsewhere, equations should be cited as e.g. ‘equation (1)’.
    Authors must submit the final version of the manuscript as an editable word processor file via the submission system. Upon notification of the acceptance of your manuscript, the corresponding author must license JSWE to reproduce the work in JWET as mentioned in the OPEN ACCESS section in this document.
    Authors will receive galley proofs approximately two months after manuscript acceptance, and any suggested corrections should be returned within one week; note that major changes are not permissible at this stage of the production process. Authors who expect to be away at this time should notify the Editorial Office of their absence and the contact method to be used during this period. If the galley proofreading process is delayed, the publication of your article may be postponed.
