JAKARTA - The Ministry of Public Works and Public Housing (PUPR) noted that the progress of the construction of the Bulango Ulu Dam in Bone Bolango Regency, Gorontalo, has reached 65 percent to date.

Director General of Water Resources of the Ministry of PUPR Bob Arthur Lombgia said the dam construction was carried out at a cost of Rp2.42 trillion, which would have a capacity of 84 million cubic meters (m3).

"Currently, the progress of the construction of the Bulango Ulu dam is specifically for the dam structure, which is 65 percent," he said in a statement uploaded by the Ministry of PUPR shared on his official Instagram account @kemenpupr, quoted on Saturday, May 11.

Bob explained that his party is currently also working on a 10 kilometer long relocation access road (km). Thus, the total progress of the construction of the Bulango Ulu Dam and the access road reached 48.4 percent.

Once operational later, the dam will be used for the purposes of raw water irrigation and flood control.

For information, the Bolango Ulu Dam has a fairly large capacity, namely 84.10 million cubic meters (m) to support an irrigation area of 4,950 hectares (ha), especially in the Lomaya Irrigation Area (DI), DI Alle and DI Pilohayanga.

Therefore, it will increase the planting intensity (from IP 265 to IP 300) in the rice-padi-palawijia pattern when compared to the rainshed method which only produces one harvest a year.

In addition, this dam with an upright core rock type has an inundation area of 483 hectares (ha) which can be used as a reservoir for flood control in the downstream area of the Bolango River.

Water sources originating from the Bolango river basin (DAS) will be controlled by dams, especially during the rainy season by reducing flood discharges to 414 cubic meters per second. Then also have the potential as a source of 4.96 MW of electricity.

As for other benefits from the construction of this dam, namely being able to meet the raw water needs of 2,200 liters per second with the assumption of serving 2 million people.
