JAKARTA - PT Waskita Karya (Persero) Tbk is targeting the completion of the Jragung Dam construction in 2025.

Waskita Karya Operations Director II Dhetik Ariyanto stated that the company is currently focusing on working on the National Strategic Project (PSN) so that it can be completed on time.

Waskita, he continued, also continues to pay attention to quality according to applicable standards.

"Waskita is optimistic that it can complete the Jragung Dam according to the specified target. Our team in the field is also increasing productivity and performance, so that the community can immediately feel the benefits of the project," he said in an official statement, Saturday, November 16.

He said that later the Dam, which has a capacity of 90 million cubic meters, can supply raw water needs of one cubic meter per second (m3/sec).

As much as 0.5 m3/sec of which, he said, is for Semarang, then for Demak and Grobogan, each of which is 0.25 m3/sec.

Then it is able to flow water to the Jragung Irrigation Area (DI) up to 4,528 hectares (ha). The dam construction will be followed by the construction of its irrigation network, thus supporting the food security program which is currently a priority of President Prabowo Subianto

"Farmers' productivity is certain to increase. Previously they could only plant once a year, but after there was irrigation water flow from the dam, it could reach two to three times," he explained.

The dam with a peak elevation of 119.5 meters, he continued, is able to reduce the risk of flooding in downstream areas from 378 cubic meters per second to 170 meters per second.

So it can reduce flooding by 45 percent in the Semarang area.

This project is estimated to be a Micro Hydro Power Plant (PLTMH) with a capacity of 1,400 kilowatts (kw). Then it has the potential to be developed in the tourism and agrotourism sectors.

"Residents can feel other benefits from the Jragung Dam, because we make the area around the project a green and attractive area to visit. The community is also involved in planting fruit there," he said.

For information, the Jragung Dam began construction at the end of 2020 through three work packages. Package I was carried out by PT Waskita Karya with a contract value of IDR 806.3 billion.

This project is one of 61 dams built by the government through the Ministry of Public Works (PU) during the 2015-2025 period.
