Wastewater management is crucial for preventing environmental pollution, maintaining the availability of clean water, and reducing the rate of land subsidence, particularly in urban areas like Jakarta. In line with the Jakarta Sewerage System (JSS) initiative, Ancol Subdistrict is part of Zone V, where the Ancol Wastewater Treatment Plant (WWTP) has been built with a capacity of 4,000 m³/day. Effluent from the WWTP has the potential to be reused as clean water. It requires planning for the construction of a Recycled Water Treatment Plant (IPRW) to process WWTP effluent into non-potable clean water. The IPRW will be constructed in two phases: the first phase in 2025 and the second phase in 2030, each with a capacity of 2,000 m³/day. The treatment technology is selected based on effluent water quality analysis, using a matrix method to compare the efficiency of alternative technologies. The chosen treatment sequence includes coagulation, slow sand filtration, and disinfection, which will produce clean water that meets the quality standards regulated by the Ministry of Health Regulation No.2 of 2023. The produced clean water will be sold to PT Taman Impian Jaya Ancol at a lower price than conventional clean water, creating a sustainable circular economy model. Financial analysis using the NPV and BCR methods indicates that the IPRW project is viable, with an NPV of IDR 22.9 billion and a BCR of 1.59, demonstrating significant profit potential from the implementation of the IPRW in Ancol.
