Since 1 April 2020, PUB had assume an additional role as the nation's Coastal Protection Agency, safeguarding Singapore's coastline against the threat of rising sea levels. As a low-lying island, Singapore is particularly susceptible to the threat of rising sea levels.
At present, about 70% of Singapore's coastline is protected from erosion by waves and storms, using structures such as concrete seawalls and stone revetments. The rest of the coast consists of natural areas such as beaches and mangroves.
PUB is interested in solutions that can protect our coastlines from rising sea levels as well as erosion by waves and storms, and reduce the landtake for such measures without compromising on structural stability. We are also keen to explore innovation in material science and construction engineering that allow for incremental enhancements of the coastal protection measures.
We are also open to explore innovative techniques that incorporates nature or urban landscape features into our coastal protection measures. Nature-based solutions complementing traditional engineering structures could allow us to protect and improve the natural environment and biodiversity while urban landscape features could be functional for local residents and help justify the cost required.
