Since 19 July 1999, installation of sewerage treatment has been built in Surakarta. There are two different kinds of system, on site and off site system. The off site system is a pipe system while the on site system uses tools like the septic tanks. Surakarta has done a lot of improvement to increase the quality of the sewerage, as an example, there has been an increase of sewerage capacity, development of secondary pipe network within the business area.
Further there can be drawn a long history of drinking water supply. 57 % of Solo’s population have access to drinking water from PDAM. There are still many problems to face, including water loss of almost 40% due to old pipes and the water meter. For the future, government of Surakarta has two strategies: for short term, they want to increase water treatment capacity in Semanggi. For the long time planning, they want to make some cooperation with the surrounding cities which are Wonogiri, Sukoharjo, Surakarta, Karanganyar, and Sragen (WOSUSOKAS) in order to have advantages of regional hydrogeological conditions.
After the presentation, there has been a productive discussion about water and waste disposal management in Surakarta. (Annisa/Johanna)After the presentation of the project Solo Surakarta, we went into the city to lunch. When we were all full of the great meal, we went on to visit the waste water installation in the southern part of Solo. Here we could see how the sewersystem works. The installation is one of the two working waste water installations of the city. In front of the air streatment bassin was a buffer installed, wich recieves the incoming waste water. This buffer gives a controlled amount of waste water to the air bassin. After this proces of treatment the waste water is discharged into the river.
