Jakarta, August 19, 2025 – Jakarta once again reaffirmed its role as a strategic investment hub in Southeast Asia through the Jakarta Investment Festival (JIF) 2025, held at New Port A and B, St. Regis Jakarta. Carrying the theme “Jakarta the Epicenter of ASEAN: Invest Smart for Global Start”, the forum brought together government representatives, investors, and business leaders to discuss the city’s trajectory towards becoming a Global City.
This year, the forum placed a strong emphasis on the water supply, sanitation, and wastewater management sectors areas that are not only fundamental needs but also essential foundations for sustainable urban development. For Greenwise Consulting, these sectors present significant opportunities for sustainable investment while supporting Jakarta’s vision of becoming a global city.
Jakarta’s Path to Becoming a Global City: Vision 2030 and 2050
In her opening remarks, Tona Hutahuruk, Head of the Jakarta Investment Center, highlighted Jakarta’s ambitious targets for improving its global city ranking. “In 2023, Jakarta was ranked 34th in the Global City Index. Our vision is to enter the Top 50 by 2030 and the Top 20 by 2050. It is ambitious, but this is the direction Jakarta is heading,” said Tona during her keynote address.
She further noted that JIF is not only a platform for discussions and one-on-one meetings but also a showcase of 24 cross-sector projects ready to be developed with investors, ranging from property and transportation to tourism, water supply, and wastewater management.
Jakarta’s Sanitation Challenge and Paljaya’s Solutions
Sanitation was one of the key topics at JIF 2025. Azri Indiani, Director of Engineering and Business at Perumda Paljaya, reported that currently, only 23% of Jakarta’s 10.6 million residents have access to safe sanitation. Alarmingly, 0.19% of the population still practices open defecation.
Paljaya is developing a zonal wastewater management system. While some facilities are already operational (Zones 0, 1, and 6), Zones 5 and 8 are being offered to investors through public-private partnerships (PPP). “We are opening opportunities for collaboration, both in large-scale projects and pilot initiatives. Jakarta needs investment, not only to build infrastructure but also to ensure the sustainability of sanitation services,” said Azri in her project presentation.
Specifically, Zone 8 is projected to have a treatment capacity of 160,000 m³ per day, with an estimated initial investment of USD 818 million. The project is urgent, as it is directly linked to the NCICD (National Capital Integrated Coastal Development) program aimed at preventing pollution in North Jakarta’s coastal areas.
PAM Jaya: Targeting 100% Water Service Coverage by 2029
Beyond sanitation, water supply was another major focus at JIF. Siti Harmi Harahab, VP of Strategy & Project Governance at PAMJAYA, emphasized that water service coverage in Jakarta currently stands at 73%. The Governor of Jakarta has directed PAMJAYA to accelerate its target of achieving 100% coverage by 2029, one year ahead of the initial plan.
“We need to add one million new customers, build 7,000 kilometers of pipeline, and revitalize our treatment facilities. The challenges are significant, including reducing non-revenue water from 49.5% to 29%. However, with the support of investment, we are confident we can achieve this target,” said Harmi.
Priority projects identified by PAMJAYA include:
- Condet Water Treatment Plant (WTP) – 1,000 liters/second capacity
- Muara Karang WTP (revitalization) – 750 liters/second capacity
- Semana WTP (new) – 200 liters/second capacity
- West Flood Canal WTP (new) – 500 liters/second capacity
Water and Sanitation Investment Needs: A National Perspective
Investment in Indonesia’s water supply and sanitation sector continues to face a significant financing gap. The Provincial Government of DKI Jakarta, through its Water Supply Investment Potential document (2023), identified several projects in treatment plant development and network expansion requiring private sector participation.
The Ministry of Public Works and Housing (PUPR), at the Indonesia Water and Wastewater Expo and Forum 2025, emphasized that water supply and sanitation are among the national priority infrastructure sectors, offering substantial opportunities for investors through PPP schemes and alternative financing models. These align with the RPJMN 2020–2024 national targets of 100% access to safe drinking water and 90% access to safe sanitation. This indicates that investments in Jakarta’s water and sanitation sector are not only urgent but also strategic for achieving Indonesia’s sustainable development agenda.
