05 October 2022

Penajam Paser Utara, October 5, 2022 - Supporting infrastructure development in the Capital of the Archipelago (IKN), PT Brantas Abipraya (Persero) Sepaku Semoi Dam in Tengin Baru Village, Sepaku District, North Penajam Paser Regency, East Kalimantan. The dam, which will reduce flooding in IKN, will also become a source of water in the area. Ensuring that the work was completed properly, Assistant Deputy for Infrastructure Services at the Ministry of State-Owned Enterprises (BUMN) Hendrika Nora Osloi Sinaga accompanied by the Managing Director of Brantas Abipraya, Sugeng Rochadi, came to visit the progress of the dam work.


“The construction of this dam is proof of Brantas Abipraya's commitment to supporting national water and food security, as well as reducing flooding by 55%. As the main water source to support the needs of the IKN community, water from the Sepaku Semoi Dam can also be drunk directly,” said Sugeng Rochadi, President Director of Brantas Abipraya.


Sugeng added that the ready-to-drink water facilities provided to the local community cannot be separated from the technology used. The water installation will use technology from the Hwaseong Water Purification Plant from South Korea (South Korea). The Minister of Public Works and Public Housing (PUPR), Basuki Hadimuljono said that the South Korean Ministry of Environment would help build a water purification installation with a capacity of 300 liters/second through a grant.


The Sepaku Semoi dam has a capacity of 11 million cubic meters with a water flow of 2,500 liters per second. Adding to the supply of raw water, this dam has an area of ​​​​approximately 280 hectares so that later during the dry season the Sepaku Semoi Dam can support the water supply, so people no longer need to worry about drought in the rice fields.


This is a national strategic project (PSN) that will increase the supply of raw water for the Balikpapan and North Penajam Paser areas. Starting construction in July 2020, the dam targeted for impounding by the end of this year has a height of 25 meters and a length of 450 meters. The type of dam is homogeneous soil fill. This dam has the potential to become one of the tourist destinations in East Kalimantan.


For additional information, apart from completing the Sepaku Semoi Dam, Brantas Abipraya, known as the champion contractor in the construction of this dam, is also working on several dam and irrigation projects that have become PSN, whose locations are spread across the country. Among them are the tallest dams in Indonesia, namely Bener Dam located in Purworejo, Central Java, Semantok Dam in Nganjuk, East Java which will be the longest dam in Southeast Asia, and Ciawi Dam in West Java which is the first dry dam in Indonesia.


In addition to providing added value to the area around the dam built by Brantas Abipraya, the ongoing and completed work on water resources infrastructure is the answer to the challenges of climate change that are currently being faced. As is well known, this causes water shortages during the prolonged dry season and high rainfall which can lead to catastrophic flooding.


“Brantas Abipraya will always play an active role in contributing to the development of Indonesia, one of which is through the construction of the Sepaku Semoi Dam. It is proof that we are always here for the country in preparing infrastructure to support the Government in overcoming the challenges of global climate change. In addition to the need for clean water and flood control, this dam can later be used as a tourism area for reservoirs and conversion of the Tengin Baru Watershed in Sepaku District, Sugeng concluded.
