Abstract: This study aims to identify current conditions of water supply, sewage, wastewater treatment and sanitation condition of ger (traditional nomadic house) areas in Ulaanbaatar city, and to investigate the willingness to pay for improvements in the water supply and wastewater treatment system’s capital cost and operation & management of Ulaanbaatar city residents, using the Tobit model of contingent valuation method (CVM). The problems in ger area are lack of drainage system, unimproved sanitation technology, and unsafe water supply in addition to direct discharges of the wastewater into the pit latrine, soak pits, yards, and streets from the residents of ger areas. A field survey conducted in Damba planning unit which is defined by Urban Development Trend 2030. It is locating in the northeast part of the Ulaanbaatar city and residents all live in the ger and owner-built house housing. The survey collected 298 samples from the Damba planning unit. An average total willingness to pay for water supply and wastewater treatment facility installation was maximum 1000.0 (thous.MNT), An average total willingness to pay for operation and management was maximum 3.0 (thous.MNT) per month. The Tobit model result shows the willingness to pay for installation significantly influenced by income levels and housing. Willingness to pay for operation and management significantly influenced by family size, income level but not significant by the housing. Education, time for water access, and water consumption were not significantly related to both willingness to pay for installation, and operation and management.
