Declaration on accessibility
This accessibility statement applies to the website of Wirtschaftsbetrieb Mainz AöR published at www.wirtschaftsbetrieb.mainz.de.
Wirtschaftsbetrieb Mainz AöR uses a subpage (microsite) of the central online offering Mainz.de.
The state capital of Mainz has been working continuously since 2014 to make its online offerings accessible. This accessibility statement in accordance with EU Directive 2016/2102 applies exclusively to the central online offering Mainz.de and the microsites of Mainz.de; it does not apply to linked offerings or services or those embedded via iFrame or code.
Status of compatibility with the requirements
Wirtschaftsbetrieb Mainz AöR strives to fully comply with the current accessibility requirements in accordance with the Web Content Accessibility Guidelines (WCAG). Mainz.de and the website www.wirtschaftsbetrieb.mainz.de are largely compliant with the current accessibility guidelines (BITV 2.0, 2019/WCAG 2.1).
The HTML code is generated by the content management system used for Mainz.de in accordance with the rules for accessible web design (BITV 2.0). The front-end code (HTML and CSS) is validated according to W3C specifications. Special functions for changing the font size and a special contrast mode are not implemented, as these functions are already provided by browsers or individual assistive technologies.
A special feature of accessibility on Mainz.de and the www.wirtschaftsbetrieb.mainz.de website is the integration of a text-to-speech solution that enables all content on the central online offering, including microsites, to be read aloud without the need for individual assistive devices.
BIK BITV test in summer 2021
In the summer of 2021, the Digital Accessibility Competence Center at Stuttgart Media University was commissioned to conduct a BIK BITV test. The abbreviation BIK stands for Barrierefreie Information und Kommunikation (Barrier-Free Information and Communication). The BIK BITV test is a procedure for comprehensively and reliably testing the accessibility of websites and web applications based on BITV 2.0 / EN 301 549. The BIK BITV test checks 32 additional test steps of EN 301 549. Ten
pages were tested. The specific selection of pages to be tested was made independently by the testing agency. Result: The BIK BITV criteria, which go beyond the WCAG 2.1 standard, are largely met on the tested pages. Among other things, the test revealed a need for further work in terms of contrasts, icon sizes, the avoidance of font graphics, the adaptability of text spacing, alternative texts for control elements, the use of HTML structural elements, and the structuring of content.
The test results, which have been documented in detail and explained in discussions, will now be used as a basis for further work on the accessibility of mainz.de as part of the relaunch planned for 2025.
Accessibility in the editorial processes
Wirtschaftsbetrieb Mainz AöR wants www.wirtschaftsbetrieb.mainz.de to be accessible to everyone.
We therefore strive to ensure accessibility in our daily editorial processes. This includes, for example: generally understandable language, clear text structures, the appropriate use of tables, the conscientious use of CMS functions for the correct marking of links and abbreviations with corresponding HTML tags, the technically mandatory marking of images and graphics with alternative text, descriptive file names, and much more.
Our employees keep their knowledge of accessibility up to date and adapt it as necessary.
Specialist applications
www.wirtschaftsbetrieb.mainz.de provides GIS-based online planning information that enables citizens and companies to automatically access sewer inventory plans. This is a specialist application that does not currently provide any accessibility aids. At wirtschaftsbetrieb.planauskunftstadt.mainzde, the employees of the municipal utility company are available to provide personalised support.
The "responsive design" and "WCAG 2.1" standards are taken into account when introducing new specialist applications.
Non-accessible content
The content listed below is not fully accessible in accordance with the exemption due to disproportionate burden under Article 5 of Directive (EU) 2016/2102:
- PDF documents (mostly) and media with other file formats (e.g., Word)
- Videos
- Audio files
- Content in easy language and sign language is still being expanded
Wirtschaftsbetrieb Mainz AöR is working on further expanding its accessible offerings.
Preparation of this accessibility statement
This statement was created on April 24, 2025.
