BP Batam Assesses Clean Water Management Systems, Look for New Alternative Sources

TRIBUNBATAM.id, BATAM -  BP Batam's Facilities and Environment Business Entity is in the process of designing a clean water management system and creating alternative water sources.

During this time, clean water is collected from rain that falls during the rainy season in Batam City. The rainwater then flows in the catchment area, then accommodated directly in reservoirs.

At present, of the seven reservoirs in Batam, only five of them are the main raw water sources for industrial and household needs, namely Sei Harapan dam, Mukakuning dam, Sei Ladi dam, Nongsa dam, and the largest, Duriangkang dam. 

According to the Director of BP Batam's Facilities and Environment Business Entity, Binsar Tambunan, with the condition of rainfall intensity decreasing in the last two years, the possibility of reservoirs receding becomes inevitable.

"The rainfall that has fallen over the past two years has dropped to below 2000 mm per year," said Binsar, Wednesday (5/27/2020). 

BP Batam also considers that this needs to be done to examine other ways to produce clean water besides expecting rain to fall in the reservoir.

Some schemes designed are; first, by optimizing the function of the Waste Water Treatment Plant or called (IPAL); Second, start the desalination plant system.

The construction of the IPAL, which began in 2017, actually functions for the treatment of wastewater recycling. Initially, household wastewater will be channeled to the IPAL, then processed into clean water that can be reused. 

This development is expected to be completed in 2021, and clean water products can be enjoyed specifically by the industrial estate in 2022.

Along with the construction of WWTP, BP Batam is also reviewing a desalination plant project, which is processing seawater into clean fresh water that can be consumed.

This desalination process will generally produce, not only clean water but also kitchen salt products as a byproduct.

However, one obstacle to desalination plants is that this technology still requires expensive costs. The cost of this program is predicted to reach Rp. 25 thousand to Rp. 35 thousand per m³. 

Therefore, the team is still looking for the right location to build this desalination plant project, with the target object, sandy soil, in order to obtain water with a low salinity level so that the program cost can be reduced to only around Rp 10,000 per m³.

It is planned that in 2022, the water source from the desalination plant can be utilized by the industrial estate, as well as being drafted for the domestic realm in 2025. (Ttribunbatam.id/Hening Sekar Utami)
