[Penelitian ini membahas relasi negara (pemerintah kota DKI Jakarta) dan swasta(Suez Environment yang diwakili Mercy Corps) dalam menjalankan layanan sanitasi/fasilitas limbah cair bagi warga RW 6, Kelurahan Kalideres, Jakarta. PemerintahDKI Jakarta belum bisa memberikan pelayanan sanitasi pada warga Jakarta. Alasanyakarena cakupan layanan sewerage hanya mencakup 3% daerah DKI Jakarta (di luarpulau seribu). Warga di 97% daerah sisanya harus memenuhi sendiri fasilitassanitasinya dengan tangki septik. Pemerintah masih belum memberikan prioritas padalayanan limbah cair. Lebih lanjut lagi mereka kekurangan sumber daya untukmemberikan layanan yang layak pada seluruh warga Jakarta. Akibatnya swastamasuk pada layanan limbah cair, meski swasta juga ternyata membawakepentinganya sendiri. Penulis menggunakan teori Urban Regime dan konsep PublicPrivate Partnership untuk membahas hasil penelitian., This research explains about relation between state (Jakarta municipal) and private(Suez Environment represented by Mercy Corps) in managing sanitation/ wastewaterfacility for resident in RW 6, Kelurahan Kalideres, Jakarta. Jakarta municipal can notgive basic service of sanitation to Jakarta resident since sewerage coverage onlycovers 3% of Jakarta area. Resident in 97% of the rest area has to establish their ownsanitation/ wastewaster facility with septic tank. The government has not takenpriority to wastewater service. Moreover the government also lacks of resources togive wastewater service to all of Jakarta resident. Consequently, private couldparticipate in managing wastewater system, although private has its own interest. Thewriter uses Urban Regime theory and concepts of Public Private Partnership toexamine this phenomenon.]
