BadakSinga is one of Water Treatment Plant in Bandung's Municipality Water Companies (PDAM Bandung). In processing its drinking water, residue is produce. The residue contains such materials as muddiness-causing sludge to the raw water, organic and non-organic solidity, alga, bacteria, viruses, colloids, and other chemical substances either naturally formed or as coagulant precipitated during the process of producing drinking water. Residue coming from the process of producing drinking water, until recently is still flown to the public water supply (Cikapundung River). This residue disposing activity has affected not only the Cikapundung River's biota but also its aesthetic aspect. Currently, Indonesian Government has issued Regulation No. 16, 2005, in which under item 3 of the article 9, it is stipulated that the waste produced from any processing must be treated before it is drained. Thus, we need sludge treatment system which doesn't only fulfill the regulation, but also decrease the influence for Cikapundung River, and increase quality of the environment. The units for sludge treatment are going to be made. There are three processing steps, those are thickening, conditioning, and dewatering. The best alternative option is done by considering technical and environment aspect. From these considerations, the sludge treatment system with 1 unit of sludge distribution tank, 2 units of Gravity Thickener, 1 unit of sludge collector well, 1 lime solvent tank, 1 conditioning tank, 2 units of lime Hooper, 2 units of polymer Hooper and 2 units of Belt Filter Press is chosen.
