BEFORE YOU BEGIN
Ethics in publishing
You will be required to accept the IWA Publishing Ethics Statement for Authors when you submit your paper to the journal. The statement covers authorship, originality and conflicts of interest. Please read this statement to ensure your submission complies.
Note that conference proceedings are a form of publication.
To verify originality, your article may be checked by the originality detection service CrossCheck.
Changes to authorship
If you wish to add, delete or rearrange the authors of your accepted paper:
Before online publication: The corresponding author should contact the Journals Manager, and provide (a) the reason for the change, and (b) the written consent of all co-authors, including the authors being added or removed. Please note that your paper will not be published until the changes have been agreed.
After online publication: Any requests to add, delete, or rearrange author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.
If your paper is selected for publication you will be expected to sign our copyright assignment form. Where necessary you must obtain permission to publish material protected by copyright. Provision is made on the form for work performed for the United States Government (for which Copyright cannot be assigned) and other extenuating circumstances.
For open access articles: Upon acceptance of an article, authors will be asked to complete an 'Exclusive Licence Agreement' (for more information see our Rights and Permissions page). Permitted third party reuse of open access articles is determined by the author's choice of user licence. More information is available on our Open Access page.
For the rights of the author to reuse your work, please refer to the Rights and Permissions page.
Role of the funding source
You are requested to identify who provided financial support for the conduct of the research and/or preparation of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the article for publication. If the funding source(s) had no such involvement then this should be stated.
If your paper is accepted for publication, you will be able to choose from two publication options.
Open Access papers are freely available on http://www.iwaponline.com. Usage of papers published open access by third parties is defined by the type of Creative Commons user licence selected by the author (see all options on our Open Access page).
A fee is payable for the IWA Publishing Open (open access) option.
Papers which are not published “open access” are available to the journal subscribers, as well as developing countries through Research4Life programmes.
No fee is payable by the authors.
Readers without a subscription can pay a one-off fee to download the paper.
Papers must be in good, grammatically correct English. If your paper cannot be understood, it will be rejected. If English is not your native language, you should seek the assistance of a colleague or professional translator. IWA Publishing has partnered with Peerwith, who offer a language editing service: https://iwap.peerwith.com/
In addition, you should always have your manuscript read by at least two other people to avoid typing errors before submitting to a journal.
Articles should be provided in electronic form (uploaded to our online submission site http://www.editorialmanager.com/wpol/) and comply with the instructions below.
This journal has no page charges.
You are required to submit, with the manuscript, the names and addresses of at least 3 potential referees that can give an independent review.
Major corrections cannot be undertaken by either the editor or the publishers; if your paper is not prepared in accordance with these instructions it may not be considered further. Where requested to do so in the course of the peer review process, authors must revise their papers within one month of the request; otherwise the contribution will be considered withdrawn.
Use of word processing software
The preferred format for electronic versions is Microsoft Word, though we can accept most other word-processing packages in PC or Macintosh formats; however, please do not supply your typescript as a PDF. Authors should not add their own macros. Please supply only the final version of your file (with no hidden text), to avoid any risk of old versions of the text being used in error.
The source files of figures will be required whether or not you embed the figures in the main text (see below).
Do not number or letter section headings.
Use line numbering throughout your paper.
Papers should be well structured; they must comprise:
- Short title of no more than 80 characters
- Author name(s), full postal addresses for each author. Include the e-mail address for the corresponding author only.
- Abstract: no more than 200 words briefly specifying the aims of the work, the main results obtained, and the conclusions drawn. Citations must not be included in the Abstract.
- Keywords: up to 10 keywords (in alphabetical order) which will enable subsequent abstracting or information retrieval systems to locate the paper.
Main text: for clarity this should be subdivided into:
- Introduction: describing the background of the work and its aims.
- Methods: a brief description of the methods/techniques used (the principles of these methods should not be described if readers can be directed to easily accessible references or standard texts).
- Results and Discussion: a clear presentation of experimental results obtained, highlighting any trends or points of interest.
- Conclusions: a brief explanation of the significance and implications of the work reported.
- References: these should be to accessible sources. Please ensure that all work cited in the text is included in the reference list, and that the dates and authors given in the text match those in the reference list. References must always be given in sufficient detail for the reader to locate the work cited (see below for formats). Note that your paper is at risk of rejection if there are too few (<10) or too many (>25) references, or if a disproportionate share of the references cited are your own.
Supplementary Material: Appendices and other Supplementary Material are permitted, and will be published online only.
For Review Papers the organisation of the paper can be different. It is however important that a review is more than a summary of the literature; an in-depth critical discussion is essential for acceptance of a review paper.
Nomenclature and Units
Please take care that all terminology and notation used will be widely understood. Abbreviations and acronyms should be spelled out in full at their first occurrence in the text. In describing wastewater treatment processes authors should consult Corominas et al. (2010). New framework for standardized notation in wastewater treatment modelling. Water Science & Technology, 61(4), 841-857.
SI units are strongly recommended. If non-SI units must be used, SI equivalents (or conversion factors) must also be given. Please use the spellings 'litre' and 'metre' (a 'meter' is a measuring instrument).
Please use a decimal point rather than a comma in numbers (i.e. 3.142 not 3,142).
The unit ‘billion’ (109 in America, 1012 in Europe) is ambiguous and must not be used.
Write equations in dimensionless form or in metric units. Please use italic letters to denote variables (in text or in displayed equations).
All figures should be embedded correctly positioned within your Word files, and should also be supplied as separate graphics files in their original formats. EPS, TIFF or PSD formats are preferred. Use a minimum of 300dpi.
The journal is printed in black and white, with colour graphics in the online version. Authors can have figures printed in colour at a cost of £350 per figure.
Figures should appear in numerical order, be described in the body of the text and be positioned close to where they are first cited. Each figure should have a caption which describes the illustration, and that can be understood independently of the main text. The caption should be given in the text, and not on the figure itself.
Make sure all figures and tables will fit inside the text area.
Because figures may be resized in the course of production please use scale bars and not magnification factors.
Please submit tables as editable text and not as images. Number tables consecutively in accordance with their appearance in the text and place any table notes below the table body. Be sparing in the use of tables and ensure that the data presented in them do not duplicate results described elsewhere in the article. Please avoid using vertical rules.
Citations in text
Use surname of author and year of publication: Jones (2002) or (Jones, 2002).
Insert initials only if there are two different authors with the same surname and same year of publication.
Two or more years in parentheses following an author's name are cited in ascending order of year, and two or more references published in the same year by the same author are differentiated by letters a, b, c, etc. For example: Brown (1999, 2002, 2003a, b).
Different references cited together should be in date order, for example: (Smith, 1959; Thomson & Jones, 2008; Green, 2015).
If a paper has been accepted for publication but has not been published the term "(in press)" should be used instead of a date.
If a paper has been submitted but not definitely accepted the term "(submitted)" should be used. If the paper is still being prepared the term "(in preparation)" should be used.
The abbreviation "et al." should be used in the text when there are more than two co-authors of a cited paper.
Please double-check: every citation in the text must match up to an entry in the reference list and vice-versa.
We use digital object identifiers (DOIs) to link references to the source material. This can only be done if the data provided in the references are correct. Please be very careful, especially when copying references, to ensure that surnames, journal/book titles, publication year and pagination are all correct. Please include DOIs where available.
List of References
References should be listed alphabetically at the end of the paper. Although "et al." is preferable in the text, in the list of references all authors should be given.
Journal reference style:
Kalbermatten, J. K. (1991). Water and sanitation for all, will it become a reality or remain a dream? Water International, 16(3), 121-126.
Note that to unambiguously identify articles published in Water Science and Technology before 2008 the issue number as well as the volume number is needed.
