Mayor Fadlun Mak Ujud said DBKL is preparing short, medium, and long-term plans to reduce water flow pressure during heavy rain, especially in low-lying areas, Berita Harian reported.

Fadlun said land acquisition was also underway in Segambut to facilitate the construction of an on-site detention pond to temporarily store rainwater before releasing it into rivers.

He added that DBKL would tighten enforcement at construction sites to ensure proper installation of barriers and silt traps to prevent water and mud from flowing into residential areas.

He said areas previously unaffected by floods were now beginning to experience them due to rapid development and land clearing, which had reduced natural water absorption.

“For hillside areas, development will no longer be allowed to be carried out all at once, but must be done in phases. Otherwise, the area will continue to face flood risks,” he was quoted as saying.

Likewise, MBPJ said it had drawn up a long-term action plan with the irrigation and drainage department (JPS) to reduce the risk of recurring floods in Petaling Jaya.

“To minimise the risk of recurrence, MBPJ and JPS have drawn up an action plan involving physical infrastructure upgrades and drainage innovation measures,” it said in a statement.

The measures include the construction of floodwalls along critical stretches of Sungai Penchala, the installation of a river overflow control system at major drain outlets, and flapgates at smaller outlets leading to Sungai Klang.

MBPJ also said premises would no longer be allowed to discharge water directly into rivers.
