Working towards a project legacy, signage was designed and installed at each Project Ô demosite. A total of 5 signs (size A0) were designed: one for the project and one for each demosite. It was envisioned that these would promote the work at individual demosites and give an overview of Project Ô, including goals, the technology modules, and the other demosites. A first draft of each signage was produced using the updated content of the website and brochures. These drafts were sent to each of the demosites for review and approval in February 2022. During March 2022, a series of meetings were held with colleagues from SOCAMEX and Acquedotto Pugliese to clarify and refine some of the infographics. By the end of the month, all signages were approved and the printed version of the files were sent to the partners.
