Sewage System
In Mongolia, you'll have to make some mental changes. Outside of Ulaanbaatar, Western-style restrooms and sewage systems are uncommon. Most restrooms are either large expanses of terrain in front of you from which to select a location, or latrines where the flies swarm around your buttocks so noisily that you can hardly hear your own thoughts.
In terms of sewage system, prepare yourself mentally for the change. Bring toilet paper, baby wipes, and any nutritional supplements you may require. Maintain water to avoid dehydration-related digestive issues. In Mongolia, around 30% of all houses are linked to wastewater treatment plants and sewage pipes.
According to the most latest statistics from the Ministry of Construction and Urban Development, there were 103 wastewater treatment plants countrywide in 2006. However, just 40% were in regular operation and complied with environmental regulations. Over a quarter of treatment facilities were not operating on a regular basis, and 34% were inoperable.
