PT Wijaya Karya (Persero) Tbk (WIKA) continues to strengthen its role as a strategic partner of the government, particularly the Ministry of Public Works (PU), in developing basic infrastructure that directly impacts the community through its involvement in the Jakarta Sewerage Development Project (JSDP). This project aligns with President Prabowo's Asta Cita (Public Works), specifically strengthening equitable basic infrastructure development, improving public health, and maintaining environmental sustainability through a reliable urban sanitation system.
JSDP is a project to develop an urban wastewater management system (sewerage) in Jakarta, part of the Metropolitan Sanitation Management Investment Program. This project focuses on the development of a wastewater pipeline network (trunk sewer and interceptor sewer) and a wastewater treatment plant (WWTP), specifically for Zone 1 Jakarta, as an effort to support effective and sustainable urban sanitation management.
In general, the JSDP Project aims to improve the wastewater management system in DKI Jakarta, improve environmental and water quality, and encourage step-wise sewerage system development as a foundation for long-term sanitation in modern urban areas.
As of January 2026, the JSDP Zone Package 1 Project has entered the building, piping, and mechanical and electrical installation stages. The project is targeted to reach the testing and commissioning stage in October 2027.
The President Director of WIKA stated that the JSDP Project plays a strategic role in supporting the national development agenda in the sanitation sector.
"Through the JSDP Project, WIKA is committed to providing reliable and sustainable sanitation infrastructure as part of its support for Asta Cita. This project focuses not only on construction completion but also on long-term benefits for the environmental quality and public health of Jakarta," said Agung BW, President Director of WIKA.
Going forward, the JSDP is targeted to become the main foundation for realizing an effective, phased, and sustainable centralized wastewater management system in DKI Jakarta, while simultaneously supporting the government's agenda to improve the quality of life for the community through the provision of adequate sanitation infrastructure.
To ensure optimal project progress, WIKA, together with the Ministry of Public Works and relevant stakeholders, implemented strict planning and control, intensive cross-party coordination, the selection of appropriate construction methods, and the consistent application of risk and quality management throughout all stages of the work.
In terms of innovation, the JSDP Project adopts construction technologies that differentiate it from similar projects, particularly in structural work. One of the superior technologies implemented is the pneumatic caisson method in the construction of the Lifting Pump Station structure, which allows for the safe and efficient creation of large underground spaces.
The JSDP Project has had a positive impact on the surrounding community and environment, including reducing water pollution levels, improving environmental quality and public health, and supporting the sustainable development of Jakarta. Impacts that occurred during the construction period were temporary and have been managed in a controlled manner.
Through the completion of the JSDP Project, WIKA hopes to provide a reliable and sustainable wastewater management system.
