More than 35,000 people are expected to take part in Singapore's World Water Day celebrations on March 16.
Activities such as kayaking, dragon boating, cycling, mass walks and picnics will be held at 11 locations including the Marina Barrage, Jurong Lake, Lower Seletar Reservoir and Geylang River.
Among the highlights will be the formation of a giant water droplet by more than 3,000 people at the Marina Barrage, and mass yoga sessions there as well as at other locations.
The theme for Singapore's celebrations this year is Every Drop Counts. World Water Day is on March 22 internationally.
