The eco-friendly drinking water supply system (Green WSS) is an important issue in Indonesia’s development related to the low implementation of Green WSS in existing water supply building. While the current water supply system development criteria should have more efficient and eco-friendly infrastructure. This study aims to assess the implementation of Green WSS on Bregas Regional Water Supply System. Regional Water Supply System service areas of Bregas include Brebes Regency, Tegal City, and Tegal Regency with total discharge of 650 L/sec will be able to serve 52.000 connection house or some 260.000 people. Analysis method that used in this research is scoring analysis of Green WSS indicator and SWOT analysis, data collection obtained by interview, observation, and document study related to planning phase, construction phase, and operational and maintenance phase. According to the results of scoring analysis Green WSS indicator, Bregas Regional Water Supply System has a score of 264 out of 285 (green category) and based on SWOT analysis, it is in quadrant II, meaning the implementation of Green WSS shows the average condition. From those condition have been formulated 13 management strategies of Bregas Regional Water Supply System.

To achieve the target of 100% drinking water service, Central Java Provincial Government holds regional water supply system (SPAM) programmes in Central Java, one of which is Keburejo regional water supply system (Kebumen and Purworejo). During the development phase, it was delayed due to project cost overrun, which later promotes an option for Public-Private Partnership (PPP). Consequently, this option may increase the project risks. This study aims to identify and analyze the risks of Keburejo regional water supply system project when the PPP option is chosen. This research adopted a mixed research method of qualitative and quantitative approach. Respondents in this study were 22 respondents from PDAB Tirta Utama, Dinas Bina Marga and Cipta Karya (BMCK) Central Java, Satker PSPAM Central Java, BBWS Serayu Opak, Pemkab (PDAM, Bappeda and DPU) Kebumen and Purworejo, as well as Business Entity (PT. TGM). The results found 24 risk factors, classified into pre-construction (10), construction (4), and Operational and Maintenance (10). The majority of these risks are considered ‘High’ (83.33%), with the highest risks in the pre-construction (37,5%), and the majority is under the Government responsibility (66.67%). These results are useful for Government as a reference in managing the risks of PPP SPAM Regional Keburejo and other regional SPAM projects in Indonesia.
