Water pollution in the big cities in Indonesia, especially in DKI Jakarta has shown serious problems. One of the potentialsources of water pollution is domestic wastewater that is wastewater from kitchens, laundry, bathing and toilets. Theseproblems have become more serious since the spreads of sewerage systems are stiff low, so that domestic, institutionaland commercial wastewater cause severe water pollution in many rivers or shallow ground water. Bases on the fact thatthe progres of development of sewerage system is stiff low, it is important to develop low cost technology for individualhouse hold or semi communal wastewater treatment such as using anaerobic and aerobic submerged biofilter. Thispaper describes alternative technology for treatment of household wastewater or organic wastewater using anaerobicand aerobic submerged biofilter. Using this technology can decrease BOD, COD and Suspended Solids (SS)concentration more than 90 %. Ir. Nusa Idaman Said, M.Eng.Oirektorat Teknologi Lingkungan, BPPT
