Residents complain about the collapsed wall of Sentiong River at Jalan Sunter Jaya, Sunter Agung Urban Village, Tanjung Priok, North Jakarta, precisely across Sunter Selatan Dam Pump Station.

Rita (35), one of locals, said the wall was collapsed on last Sunday (11/29). According to her, it began when dredging activity around the river was going on.

"Probably it couldn't hold the load of dredging equipment, so the wall collapsed," she stated, Wednesday (12/2).

She assessed if the wall is not repaired, it could possibly spread to other points.

Head of North Jakarta Water Management Sub-Department, Kasna could not be confirmed. He did not pick up his phone. Likewise the text message, it was not replied.
