Wastewater Treatment in Indonesia Prayatni Soewondo INSTITUT TEKNOLOGI BANDUNG Faculty of Civil & Environmental Engineering Research Groups Water and Wastewater Engineering Programmed Study of Environmental Engineering 30 April 2014
Introduction Current Situation Future Developments Conclusions Contents :
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
2. Current Situation in Indonesia Population : 247,4 million (BPS, 2013) Basic sanitation : 69,51 % in urban area and 33,96% 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) ?

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. 3. Future Development
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.
