Created for this new agency set up in 1963 to unify the once separate corporations or board managing the public utilities of electricity and gas. This logo depicts a power station, gas holder and flowing water all enclosed within a circle. They denote the three essential utilities—electricity, water and gas—handled by the Public Utilities Board (PUB).
The logo was the result of a public competition won by commercial artist Chew Man Cheong. Of the 1,000 entries received, Chew's design was judged to be the best and he was rewarded with a a $1,000 prize . The competition was the third PUB organised in over a year in its efforts to find the perfect logo. They first held it only for employees, then secondary school students, before finally opening the competition to the public.
In 1976, PUB announced a new logo to signify the 24-hour service it rendered.
