Publication of papers in IWA magazines

Publication of papers in IWA magazines
Selected papers will be peer reviewed for publication in IWA Publishing’s journals Water Science and Technology, Water Science and Technology: Water Supply, or Water, Sanitation and Hygiene for Development.  Specifications for the formatting of papers are available on the IWAP website at

Instructions for Authors
These notes are to help authors prepare papers that may be selected following peer review for publication in Water Science and Technology. It is your responsibility as author to follow the instructions below.

1. Authors’ responsibilities
1.1. Papers must be in good, grammatically correct English, and if your paper cannot be understood it will be rejected. If English is not your native language you should seek the help of a colleague or professional translator.
1.2. Have your typescript read by at least two other persons to avoid typing errors.
1.3. 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authors must revise their papers within one month of the request; otherwise the contribution will be considered withdrawn.
1.4. Proofs will be sent by e-mail to the listed corresponding author. Any corrections must be returned within one week of receipt and should only cover typesetting errors.
1.5 If your paper is selected for publication you will be expected to sign our copyright transfer form. Where necessary you must obtain permission to publish material and for using any other 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.

2. Preparation of electronic versions
Articles should be provided in electronic form (uploaded to our online submission site and comply with the following basic instructions.
2.1. File formats. 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) so as to avoid any risk of old versions of the text being used in error.
2.2 Graphics. All figures should be embedded correctly positioned within your Word files; however it is most helpful if you can also supply them as separate graphics files in their original formats. EPS, TIFF or PSD formats are preferred. 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.

3. Types of submission
3.1 Research Papers: the maximum acceptable length of a Research Paper is 5000 words (less 350 words for each normal-sized figure or table you include): please do not exceed this limit or your paper may be rejected.
3.2 Review Papers: these are critical and comprehensive reviews that provide new insights or interpretation of a subject through thorough and systematic evaluation of available evidence. They should not normally exceed 8000 words. Manuscripts exceeding 10,000 words will not be accepted for review.

4. Preparation of the typescript
4.1 Text should be typed single-spaced on one side of the paper only. Do not exceed the dimensions given above. Please use a 12pt Times justified typeface. The main body text should be typed flush left with no indents. Insert one line space between paragraphs, and two line spaces between paper title, authors’ names, and addresses on the first page.
4.2 The title of the paper, author’s name(s), affiliation(s), author’s full postal address(es) and e-mail, abstract and keywords should be clearly set out on the first page of the article.
4.3 If any figures or tables are not already fixed in their correct position in the text, insert a brief note specifying which figure should be placed there.

5. Content
Papers should be well structured: i.e. they must comprise:
(1) Title, author name(s), full postal addresses for each author. Include the e-mail address for the corresponding author only.
(2) Abstract: no more than 200 words briefly specifying the aims of the work, the main results obtained, and the conclusions drawn.
(3) Keywords: 3-6 keywords (in alphabetical order) which will enable subsequent abstracting or information retrieval systems to locate the paper.
(4) Main text: for clarity this should be subdivided into:
(i) Introduction – describing the background of the work and its aims.
(ii) 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).
(iii) Results and Discussion – a clear presentation of experimental results obtained, highlighting any trends or points of interest.
Do not number or letter section headings.
(5) Conclusions: a brief explanation of the significance and implications of the work reported.
(6) 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.
(7) Supplementary Material: Appendices and other Supplementary Material are permitted, and will be published online only, hosted on

6. Nomenclature and Units
6.1 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 “Notation for use in the description of wastewater treatment processes”. Water Research 21, 135-139 (1987).
6.2 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).
6.3 Please use a decimal point rather than a comma in numbers (i.e. 3.142 not 3,142).
6.4 Write equations in dimensionless form or in metric units. Please use italic letters to denote variables (in text or in displayed equations).

7. Figures and Tables
7.1 Figures and tables should appear in numerical order, be described in the body of the text and be positioned close to where they are first cited.
7.2 Make sure all figures and tables will fit inside the text area.
7.3 Because figures may be resized in the course of production please use scale bars and not magnification factors.

8. References: citations in text
8.1 Use surname of author and year of publication: Jones (2002) or (Jones 2002).
8.2 Insert initials only if there are two different authors with the same surname and same year of publication.
8.3 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).
8.4 Different references cited together should be in date order, for example: (Smith, 1959; Thomson and Jones, 1992; Green, 1999).
8.5 If a paper has been accepted for publication but has not been published the term “(in press)” should be used instead of a date.
8.6 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.
8.7 The abbreviation “et al.” should be used in the text when there are more than two co-authors of a cited paper.
8.8 Please double-check: every citation in the text must match up to an entry in the reference list and vice-versa.

9. List of references
9.1 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.
9.2 Journal reference style:

10. Recommendation of new IWA Notation system for wastewater modelling
Water Science & Technology is encouraging its authors to use the new IWA Notation System for wastewater modeling by Corominas et al. (2010). To further the widespread use of this notation, IWA Publishing has decided to make this paper open access.
The notation was developed by a group of distinguished modelers out of a WWTmod2008 workshop and is supported by the IWA Task Groups on Good Modelling Practice (GMP), Benchmarking of Control Strategies (BSM), and the Water Environment Federation (WEF) Modeling Expert Group of the Americas (MEGA). It has also received a wide endorsement within the modeling community.
The new notation will help the community to assist in model communication, allow for direct model comparisons, and facilitate understanding of newly developed models. The paper by Corominas et al. (2010) aims at standardizing naming rules and provides examples for already published models.
We understand that changing notation is difficult when one has become used to represent concepts in a certain way, but the old notation methods had several shortcomings as a result of the much larger body of knowledge that is now available in comparison to the situation when the original notation was developed (Grau et al., 1987).
The Good Modelling Practice (GMP) Task Group will take on the task to provide assistance with any question that you may have. Please contact the journal office.
