Securing Singapore’s self-sustainability in clean water, the government has invested a considerable amount into constructing used water tunnels throughout our island.

While tunnels are generally not the most conducive environments for humans, they are dark and may contain poisonous gases in addition to posing a risk of explosion. NTU has developed a family of sewer inspection robots for the three types of sewer tunnels in Singapore.
