JAKARTA - The Ministry of Public Works (PU) reported that the physical progress of the Jlantah Dam in Karanganyar Regency, Central Java, has reached 98.52 percent and is targeted for completion by the end of December 2024.
Deputy Minister of PU, Diana Kusumastuti, instructed that the completion of the construction of the Jlantah Dam be carried out carefully while still paying attention to aspects of quality and safety.
"Hopefully this dam can be inaugurated in January 2025," said Diana in a written statement, Saturday, December 21, 2024.
The construction work of this dam was carried out by contractors PT Waskita Karya (Persero) and PT Adhi Karya KSO with a contract value of IDR 1 trillion.
The Jlantah Dam is designed with a height of 70 meters, a peak length of 404 meters, a peak width of 12 meters, and a peak elevation of 690 meters.

This water infrastructure also functions to provide raw water of 150 liters per second for Jumapolo, Jumantono, and Jatipuro Districts in Karanganyar Regency.
