KL Could Have Been Submerged, If Not For This Tunnel Built By Tun M

The recent floods in Klang Valley could have submerged Kuala Lumpur City, if not for the Stormwater Management and Road Tunnel (SMART), built by former Prime Minister, Tun Dr. Mahathir Mohamad in 2003.

According to Water and Environment Ministry (KASA) secretary-general, Datuk Seri Ir Dr Zaini Ujang on Sunday, at least five million cubic meters (5 billion litres) of floodwater was successfully diverted from entering Kuala Lumpur using the storm drainage and road tunnel.

To put things in perspective, a standard Olympic-sized swimming pool measuring 50m long and 25m wide, contains a ‘mere’ 2.5 million litres of water. That means the SMART Tunnel diverted out of Kuala Lumpur water amounting to 2,000 Olympic-sized swimming pools.

Zaini added that it was the first time in history, the diversion process was carried out for more than three hours ever since the Smart Tunnel – the world’s first stormwater tunnel with a built-in motorway – was completed in 2007.

The Smart Tunnel is touted as among the world’s greatest tunnels and had even been featured on National Geographic.

It was built by MMC Corp in a joint venture with Gamuda to mitigate the recurring floods in the city of Kuala Lumpur, the financial, business and commercial hub of Malaysia.

Opened in 2007, the Smart Tunnel functions by diverting floodwater into the bypass tunnel in the lower channel of its motorway tunnel.

The flood waters are then diverted to two reservoirs- the Kampung Berembang Holding Pond and an ex-mining pond in Taman Desa.

At 9.7 km long, the government-owned tunnel is the longest stormwater tunnel in South East Asia and the second-longest in Asia.

Construction of the tunnel started in November 2003 and cost RM1.887bn (US$514.6m).

  1. Kenapa tidak dibina terowong yang sama seperti itu dilain lain tempat diseluruh Malaysia bagi mengatasi masalah banjir, tak guna dok bangga yang itu sahaja….!!!

  2. Yaaa. Betul tu… Kenapa di KL je dan tidak di tempat lain. Masa dia jadi PM memang dok sibuk kat Kolumpo je. Sepatutnya PM kena jaga seluruh negara.
