Construction of a wastewater treatment plant (WWTP), locally known as IPAL, at Bendera Pusaka Park in Kebayoran Baru, South Jakarta, is being fast-tracked to improve water quality and enhance the park's appearance.

Based on observations at the site, the project is still underway, with heavy equipment and drilling machines operated by a third party under the supervision of the Jakarta Water Resources (SDA) Agency.

Bendera Pusaka Park Supervisor Budi Purbadi noted the lake's development is not yet complete, as it is still awaiting the WWTP's completion.

"So, it's not final yet. The water is not just dirty, but has already turned black. However, it is expected to become clean again once the WWTP is completed," he said Tuesday (3/31).

Budi explained that the park is managed by City Park and Forestry (Tamhut) Agency, while wastewater treatment and the artifical lake fall under the Water Resources (SDA) Agency.

"Once WWTP is completed, the lake will be significantly cleaner," he highlighted.

In addition, Jakarta SDA Agency's Wastewater Improvement and Control Subgroup Head Glenn Santista informed that construction began in mid-January 2026 and is targeted for completion in June.

"We are aiming to complete physical construction by June. During the process, we apologize for any inconvenience caused to the public," he said.

He added that the agency is continuing temporary measures, such as draining and cleaning water channels, to curb the decline in water quality.

Meanwhile, a resident, Desiarini (27), said she hopes the project will be completed soon, as foul odors from the water still frequently disrupt activities around the park.

"Sometimes there's no smell, but when it appears, it’s quite disturbing, especially when exercising. There have been efforts such as placing air fresheners at several spots, but they're still no match for the odor from the blackened water," she said.
