Jragung Dam construction in Central Java reported nearly complete
Waskita Karya says the dam has reached nearly 100 percent completion, with initial reservoir impounding carried out in early September 2026.
Construction of the Jragung Dam in Central Java, carried out by PT Waskita Karya, has reached nearly 100 percent completion, according to a company statement published on 8 November 2026. Initial reservoir impounding began in early September 2026.
The company states the dam is expected to irrigate 4,528 hectares of agricultural land across Demak and Grobogan regencies, supply raw water for around 720,000 people through 2040, and hold potential for a 1.4 MW mini-hydro plant and a 90.2 MW solar plant. All progress and benefit figures are company-reported and have not been independently verified; no official handover date was announced.
The project is part of the national strategic water resource programme. Its approach to completion is set to add handover documentation, as-built records and commissioning work to the project's administrative load in the coming quarter.
