The North Jakarta administration is planning to dredge a canal on Jl. Karang Bolong, Pademangan, as part of efforts to reduce the foul smell emanating from the canal and to improve the water flow.
The odor was caused by untreated waste water dumped into the canal, the acting head of the water resources office in Pademangan district, Abdul Azis, said.
“The source of the waste water is in the Ancol area,” he said as reported by tribunnews.com on Monday.
The waste water was dumped secretly into the waterway near several factories, as waste water treatment was expensive, he added.
Besides dredging the small canal with an excavator, his office will also repair several broken sections of sheet piling along Jl. Karang Bolong starting next week. The dredging was important as solid sediments in the waterway had disrupted the water flow, causing the bad smell, Azis said.
Initially, workers attempted to remove the sediment manually, but this proved impossible, necessitating the use of an excavator.
The dredging is expected to boost the waterway’s capacity, which is crucial as the rainy season is predicted to start this month.
