Jasa Tirta I Working Area Extended to Four River Territories: INPRES 9/2026

The President has issued Keputusan Presiden Nomor 9 Tahun 2026 tentang Penambahan Wilayah Kerja Perusahaan Umum (Perum) Jasa Tirta I di Wilayah Sungai Bali-Penida, Wilayah Sungai Pompengan-Larona, Wilayah Sungai Saddang, dan Wilayah Sungai Parigi-Poso (Presidential Decision No. 9 of 2026 on the Addition of the Working Area of the Public Corporation Jasa Tirta I in the Bali-Penida, Pompengan-Larona, Saddang and Parigi-Poso River Territories). The decision was stipulated in Jakarta on 22 April 2026 and takes effect on the date of stipulation.

Issue

Perum Jasa Tirta I is a state-owned public corporation established as a water resources manager, with a working area defined by regulation. Its historical remit centred on Java, and the four river territories named in this decision lie outside that base: Bali-Penida in the Bali and Nusa Penida island group, and Pompengan-Larona, Saddang and Parigi-Poso across Sulawesi. The considerations recite that integrated and sustainable water resources management is needed in these four territories, and that the Government may assign Perum Jasa Tirta I as water resources manager to carry out part of the tasks and responsibilities of water resources management while maintaining the social function of water and environmental sustainability.

Key Provisions

The dictum contains three provisions. The first adds the four river territories to the working area of Perum Jasa Tirta I as water resources manager. The second states that the corporation carries out part of the tasks and responsibilities in managing water resources in the Bali-Penida, Pompengan-Larona, Saddang and Parigi-Poso river territories in accordance with Government Regulation No. 46 of 2010 on Perum Jasa Tirta I and with legislation in the water resources field. The third provides that the decision enters into force on the date it is stipulated. The instrument therefore extends a geographic mandate without itself setting out operational duties, tariffs or transitional arrangements, all of which remain governed by the existing framework.

The choice of instrument follows from that framework. The considerations cite Pasal 3 paragraph (4) of Government Regulation No. 46 of 2010, which provides that a change to the working area of Perum Jasa Tirta I is established by Presidential Decision. The legal bases listed are Pasal 4 paragraph (1) of the 1945 Constitution; Law No. 19 of 2003 on State-Owned Enterprises, as amended most recently by Law No. 16 of 2025; Law No. 17 of 2019 on Water Resources, as amended by Law No. 6 of 2023 confirming the Job Creation Government Regulation in Lieu of Law as a statute; and Government Regulation No. 46 of 2010.

Implications

Assigning a single national operator across four additional territories creates an overlay on the river basin institutions already working in those areas. Water resources management in Indonesia is organised by wilayah sungai, with river basin organisations under the public works ministry holding operational responsibility for infrastructure and allocation. Because the decision states only that the corporation performs part of the tasks and responsibilities, the division of functions between Perum Jasa Tirta I and the incumbent basin authorities in each of the four territories will be settled through the subordinate arrangements contemplated by Government Regulation No. 46 of 2010 rather than by this instrument.

For water users, the practical questions concern service charges and asset transfer. Perum Jasa Tirta I operates on a cost-recovery model funded in part by water service fees, and its entry into a territory ordinarily brings that charging structure with it. Neither the charging arrangements nor any transfer of infrastructure is addressed in the text, which leaves both to the water resources legislation referenced in the second dictum and to instruments such as other government regulations issued during 2026.

Regulatory Context

The decision continues a pattern of expanding the working areas of the two water resources public corporations by presidential instrument rather than by amending the establishing regulation. It also sits within the wider set of 2026 measures on natural resource administration, including environmental rules issued by the environment ministry in the same year. Because the instrument takes effect immediately on stipulation, the corporation's mandate in the four territories runs from 22 April 2026, with implementation to be arranged under the existing water resources framework.
