Nearly 1 Million Jakarta Residents Will Be Served Clean Water Thanks To JSDP

JAKARTA - The government is building sanitation infrastructure in DKI Jakarta through the Jakarta Sewerage Development Project (JSDP) Zone 1 project located in Pluit, North Jakarta.

JSDP is an urban-scale Domestic Waste Management System (SPALD-T) project financed through a Japan International Cooperation Agency (JICA) loan with a total value of IDR 6.37 trillion.

As of October 2025, the cumulative progress of the construction of the JSDP Zone 1 has reached around 42 percent. The target is that the construction will be completed in 2027.

"The construction of a centralized waste water system is not only building pipes and installations, but also presenting a new civilization. Modern sanitation infrastructure will ensure a cleaner, healthier and habitable environment for the community," said Public Works Minister (PU) Dody Hanggodo in a written statement, quoted Friday, October 31.

When the project has been completed, the JSDP Zone 1 project is targeted to be able to serve up to 989,389 people or around 220,000 house connections (SR) spread across North Jakarta, West Jakarta and Central Jakarta, covering eight sub-districts.

With the availability of a modern wastewater system, said Director General of Human Settlements of the Ministry of Public Works, Dewi Chomistriana, the people of Jakarta can enjoy a cleaner and safer environment.

Meanwhile, local governments (Pemda) obtain sanitation management systems more efficiently and integrated with household networks.

Through JSDP, every household in Jakarta is protected from health risks due to water pollution, while making this city cleaner, healthier and sustainable.

In addition to having a direct impact on improving public health and quality of urban waters, the JSDP project also supports reducing carbon emissions, controlling groundwater pollution and strengthening city resilience to climate change.

It is known that the JSDP Zone 1 project includes four main work packages which are an important part of the integrated wastewater management system in the DKI Jakarta area.

Package I Construction of WWTP, includes the construction of Wastewater Processing Installation (IPAL) with a capacity of 240,000 cubic meters per day on an area of 3.9 hectares.

The facility functions as a domestic wastewater treatment center before being safely returned to the environment.

Then, Package II Construction ofwers in Area 1-1, includes the construction of a 14.3 kilometer wastewater pipeline.

Furthermore, Package II Construction of Sewers in Area 1-2 includes the addition of a 24.9 km pipeline network to expand the coverage of waste water system services.

Next, Package IV Construction ofwers in Pilot Area, focused on the construction of a jacking and PVC pipeline in the pilot area of Penjaringan District, North Jakarta, as a model of implementing modern piping system technology in densely populated areas.

The JSDP project also uses environmentally friendly modern A2O + Membrane Bioreactor (MBR) technology.

Not only that, but the sanitation project also uses the Pipe Jacking and Pneumatic Caisson construction methods, Japan's cutting-edge technique, which allows the construction of an underground pipeline network with minimal disruption to activity on the city's surface.

Indonesia became the second country in Asia after Japan implemented the method.
