Just one month later, several of the downlighters at the Rundsporthalle fail during the first competitive match for the women's basketball side. The technicians are unable to effect a repair during an eight-minute break. Despite the reduced lighting, the match is concluded.
Up to February 2009, the sports hall was officially named the Wilhelm-Dopatka-Halle after the longstanding Leverkusen mayor. It was later renamed the Smidt Arena after a new sponsor. Since the takeover of the furniture store by the Ostermann company, the hall has been called the Ostermann Arena since October 2016.

Following a thoroughly successful start with a 2–1 home win against VfL Wolfsburg, the Werkself are organising a team event.
