Tainan has become the first city in Taiwan to regulate the anti-slip coefficient of its manhole covers. With over 28,731 manhole covers larger than 900 square centimeters in the city, the municipal government requires a coefficient of over 50 BPN. The city has introduced 13 unique manhole covers totaling 130 in the old town area, combining aesthetics with anti-slip functionality, aimed at improving safety and promoting tourism. Efforts are being made to improve the anti-slip properties of manhole covers on both rainwater and sewage systems in the city, with a focus on high-traffic areas.
