Kawasan Industri Terpadu Subang is one of the government's programs in order to bring indirect investment. The planned area includes residential, apartment, commercial, and industrial areas. The area's water needs will use water sources from the Cipunagara River. the water requirement for drinking water treatmentt plants was 1073.90 liters/second. The mainstay discharge of the Cipunagara River at 90% probability was 7.159 m3/s. Minimum discharge of the Cipunagara River based on data from the last 10 years was 15.13 m3/s. Based on the results of the water quality inspection, several parameters did not meet, namely: Nitrate, H2S, turbidity, detergent, fecal coliform and coliform. Based on the parameters that do not meet the quality standards, processing alternatives are determined to reduce the value of these parameters. The method of determining the chosen alternative uses the Analytical Hierarchy Process (AHP). The selected treatmentt alternatives are using a bar screen unit, pre-sedimentation, aeration, coagulation, flocculation, sedimentation, slow sand filter, and chlorination disinfection. The selected sludge treatmentt alternatives are gravity thickener and sludge drying bed.
