Waste treatment facility, known as UPS, in Depok City is one of component in waste treatment for handling organic waste. However, carrying capacity of UPS and its ability to process of organic waste from citywide were low although 30 unit of UPS has been built over the years. The objective of this research was to map current practices and projections on waste and organic waste generation, and current organic waste collection services coverage area as well as to assess the service level of UPS at each sub-district. The amount of waste generation in 2018 is approximately 594,450 tonnes/year and projected will increase up to 886,589 tonnes/year. The organic waste fraction was projected 44% and will grow at a rate 3.9%/year in the period of 2018-2028. The amount of organic waste in 2018 is approximately 272,850 tonnes/year and increased up to 390,098 tonnes/year in 2028. Each resident projected will generate organic waste at about 118 kg/capita/year. The results showed that Cimanggis and Sukmajaya were sub-districts with the highest amount of waste and organic waste generation. Nonetheless both were having only one UPS and smallest collection services coverage area as well as high number of populations to be served for each UPS. Organic waste collection service coverage area can be distinguished by 2 schemes which were local and municipal services. It is found out that 22 UPS served for local services and 8 UPS served for municipal services. Each UPS covered averagely 16% of each total area.
