Reuters reports that Beijing is one of the driest cities in the world and that if something isn’t done to the problem they could face water shortages.

One way the city is trying to save water is by installing more efficient toilets.

“This toilet saves water,” said Zheng Qing Zhan, manager of Kuge bathroomware. “Most modern toilets use six litres of water per flush, while this uses a maximum of 3.8 litres and as little as 2.6 litres.”
