Access to improved wastewater facilities in Indonesia is below 60 per cent. Moreover, the presence of large quantities of sewage and uncollected garbage intensifies the problems of already inadequate drainage networks.

Since 2006 the Indonesian government has intensified its efforts to increase access to sanitation. In 2010 it launched the PPSP program, which sets specific goals for the three sub-sectors of wastewater, solid waste and urban drainage.

The USDP is a €14 million project within this program. Funded by Embassy of the Kingdom of the Netherlands, the aim of the program is to support the Indonesian government  in reaching these goals. Royal HaskoningDHV won an international tender in 2010 to provide technical assistance for the USDP.

The USDP supports over 400 cities and districts throughout Indonesia with technical, institutional and health related services. The program requires frequent interaction with different ministries and departments at local, provincial and national level. Key to this approach is the city sanitation strategy which has a five-year implementation plan. This methodology was developed by the 2006 -2009 ISSDP project that was also executed by Royal HaskoningDHV.

Thus through this project, Royal HaskoningDHV contributes to improved and healthy living and enriches the lives of many people in both urban and rural areas.
