PUB, Singapore’s National Water Agency, is in constant pursuit of great ideas to transform into a Smart Utility of the Future. PUB Global Innovation Challenge seeks to a​ccelerate our discovery and adoption of digital solutions and smart technologies to improve operational excellence and meet future water needs.

PUB invites companies, researchers, and innovators from all around the world to propose solutions to our challenges. Selected applicants of the PUB Global Innovation Challenge will be given the opportunity to validate their ideas and find the product-market fit in the water industry.

As one of the few utilities in the world to manage the entire water loop in a country, PUB offers unparalleled test-bedding opportunities. We are widely recognised by the international water community as a global hydrohub, with a living laboratory for testing water technologies. PUB is excited to partner innovators to co-create innovative water s​olutions, and provide support for the development, deployment and adoption of these solutions.
