Clean water for daily use is the main needs of urban community, including Bekasi. Currently the level of clean water service in Bekasi, especially by PDAM Tirta Patriot, is only 20%. Most of the people still use shallow ground wells with high pollution risk. The highest pollution risk is in Pondokgede Sub-district. Therefore, a water treatment plant will be built in Pondokgede Sub-district. The source of raw water is Kalimalang Channel with debit plan in 2018 of 21.1 m3/sec. The capacity of WTP is determined by urban water demand approach, included domestic, non-domestic, fire hydrant and urban planning for the needs of 2019 – 2038. Water demand is determined by forcasting of population and public and social facilities. Thus, the planned capacity is 700 liters/sec with the target of 50% service and 20% water losses. The raw water samples were taken in August along Kalimalang Channel. According to laboratory test of water quality, the parameters were not in accordance compared to Permenkes No. 492/Menkes/PER/IV/2010, which are turbidity, color, total coliform, and fecal coliform. Based on the pollutant parameters to be treated and the basic planning according to Babbit (1976), Fair & Geyer (1968), and Kawamura (1990), three configuration alternatives will be evaluated by the Simple Additive Weighting (SAW) method with four criterias, such as technical, operational and maintenance, economy, and environment. WTP Pondokgede is planned to be built at an elevation of ±24.2 m above sea level. Configuration of unit process used are intake builiding, equalization tank with pre chlorination, pre-sedimentation basin, coagulation, flocculation, sedimentation basin, filtration, disinfection and neutralization, and reservoir basin. The sludge processing used is sludge drying bed.
