Indonesian contractor PT Wijaya Karya (Persero) Tbk (Wika) is accelerating construction of the Jenelata Dam in Gowa Regency, South Sulawesi. As of the first quarter of 2026, the project had reached approximately 25.2% completion, with ongoing works focused on earth and rock excavation in the spillway and abutment areas, as well as the construction of the dam’s main foundation.

Several critical activities, including foundation excavation, slope protection and access road construction, are being intensified, while the main dam area is being prepared for the embankment stage, according to Wika.

Targeted for completion by 17 June 2028, the project is expected to become a strategic infrastructure asset delivering sustainable economic, social and environmental benefits.

Modern technologies have been adopted during construction, said Wika, such as the concrete face rockfill dam (CFRD) method and building information modelling (BIM) 5D, to enhance efficiency, accuracy and integrated project control.

With a storage capacity of 223.6 mil cu m, Jenelata Dam is designed to provide multiple strategic benefits, including flood control in the Jeneberang River Basin, irrigation supply for approximately 25,783 ha of agricultural land, and raw water supply for communities in Makassar, Gowa, Maros and Takalar.

In addition, the dam has the potential to support renewable energy development through a hydropower plant with an estimated capacity of 7 MW, contributing to national energy transition efforts.
