Litrak points out reasons for floods in Puchong

Sazally says unlike a single-cell box culvert system, the triple-cell box culvert system is more prone to being clogged with mud, obstructing water flow.

ABNORMAL amounts of rainfall combined with flaws in the drainage, at a stretch of the Lebuhraya Damansara Puchong (LDP) near the IOI Mall and Bandar Puchong Jaya, contributed to the severe flash floods there on Tuesday.

The rainwater recorded at 81mm, came under the Drainage and Irrigation Department’s (DID) classification of “very heavy” rain (60mm and above).
