WHO said Seongbuk, which is part of Seoul, and the city of Jinju bested other cities in Asia in providing well-maintained public sanitary facilities.

The mayors of Seongbuk and Jinju will receive their awards at the World Toilet Summit & Expo 2008 to be held in Macau starting on Monday.

WHO, which co-sponsored the contest with the Alliance for Healthy Cities, cited Seongbuk for investing a significant amount of money in rehabilitating and upgrading government-operated toilets in the area.
