She went on to study at Hwa Chong Junior College and graduated in 1986 with an Honours degree in chemistry from the Faculty of Science of the National University of Singapore.

By January 2001, Hyflux had become the first water treatment company to be listed on SESDAQ, and was upgraded to the Singapore Exchange's Mainboard in April 2003. By 2005, she had a net worth of over US$240 million, which earned her a place as the only woman on Forbes' "Southeast Asia Rich List". Lum holds several positions in public service.
