  3. 1. Introduction • The dominant pollutant in Indonesia comes from domestic wastewater; • It is estimated to contribute about 70 % of organic loading in rivers on urban areas • The water quality is always decrease, as example : some parameters COD, BOD, nitrogen and phosphate; always increases every year

  4. ? 2. Current Situation in Indonesia • Population :247,4million(BPS, 2013) • Basic sanitation :69,51 % in urban area and33,96%in rural area (Bappenas, 2009) • Centralized system is about 3%in only 11 cities in Indonesia • MDG target in 2014 (Utomo, 2012) : - centralized system will be increased until 5 % - on site system will be increased until 90% - the rest of sanitation system is about 5%. It will be developed communal system • Economic loss because of bad sanitation condition in Indonesia Rp. 1.2 million/household/year (Bappenas, 2014)

  5. Profile of Domestic Wastewater Treatment in Indonesia Off Site System (2000)

  6. Wastewater Treatment Plant In Jakarta, Bandung and Medan

  7. On site System As example : MCK= Mandi, Cuci dan Kakus (Bath, wash and water closet) around Bandung and Tangerang

  8. How to manage the wastewater from home industry ??? • Slaughtering Houses • Tofu industry • Batik industry • Cattle farming Location of Slaughtering Houses and Tofu Industries Near Bandung

  9. 0-20 KM Citarum • 19 villages from 55 villages lived around Citarum river • Around 3171 cattles

  10. Pilot Plant Model (MODEL FIXED-DOME) Ilustrasi Typical of Schematic Plant Horizontal cross section

  11. Some Villages around up stream in Citarum River Area Pilot Plant Bio-digester Sources : KPBS Pangalengan, 2014

  12. 3. Future Development • Increase access to domestic wastewater services, both on-site and off-site, in urban and rural areas; • Increase financial capacities for wastewater infrastructure developments, both on-site and off-site, and also recover treatment cost to insure services; • Increase societies contribution on developing housing effluent of domestic wastewater treatment system; • Increase the work of wastewater treatment institution and separate function between regulator and operator; • Develop regulation and apply treatments according to enacted guidelines.

  13. 4. Conclusions : Almost half of the Indonesian populations have no accessibility to wastewater facilities, which can potentially pollute the body of water. By increasing both systems (on site and off site), the degradation of raw water quality can be reduced. The development of technology can play a key role in improving these facilities. Most of the biological process is used to get biogas production. Participation of the community is also very important to be concerned about.
