The stickers, which feature the words "Baesj, Tiss, Dopapir", or "Poo, Piss, Toilet paper," have been put on more than 40 manhole covers throughout the city, TheLocal.no reported.
"We chose pink because we thought it was the best way to get people's attention," Vivi Paulsen, a senior engineer at the city's Water and Sewerage Authority, told The Local. "It's to teach people what they should not throw into the toilet."
Hopefully, the stickers, which were designed by Nucleus, an Oslo-based agency, will alert people that nothing else should be put down the toilet.
