The supply of drinking water is still a challenge in the ancient city of Bhakatpur, about 12km outside Nepal's capital city of Kathmandu.

The city is still undergoing rehabilitation after a 7.8-magnitude earthquake struck the country in April 2015.

The residents have to make daily treks to a water point to get their supply - most, like the one in this picture, use a container, locally known as "gagri", to transport the precious resource home.

It is a picture that helps to drive home the message behind World Water Day - held annually on March 22 since 1993 as a means of focusing attention on the importance of fresh water and the sustainable management of freshwater resources.

It is organised by UN Water - the United Nations inter-agency coordination mechanism for all freshwater-related issues, including sanitation, in collaboration with governments and partners.

World Water Day is part of a global mission to get safer water for all; a day for people to learn, get involved and take action.
