KUALA LUMPUR: Shah Alam remains at risk of major flooding unless alternative waterways are built to divert excess rainwater from existing rivers, says former Selangor menteri besar Dr Mohamad Khir Toyo

He said the risk was likely to increase due to rapid development in surrounding areas and Shah Alam's lower elevation compared with neighbouring areas.

He said a detailed study of the proposed Canal City flood mitigation project, which he planned during his tenure, found that it could hold hundreds of thousands of litres of water and protect Shah Alam from major floods for up to 100 years.

The project involved building an 18km canal linking Sungai Klang and Sungai Langat.
