To cope with the demand for toilet facilities during the 2010 World Expo, the Shanghai Greenery and Public Sanitation Bureau will set up 49 sets of mobile toilets.

Mobile toilets to be installed at the 2010 Expo in Shanghai will provide 360 cubicles for the public. The toilets will be high- tech facilities using solar energy for lighting and advanced ecological processing technologies.

Sanitation bureau official Liu Weiguang said, “The toilets have operated well on trials at recent big events like the Formula One Grand Prix in April.”

Director of the Sanitation Center of the Bureau of Shanghai World Expo Coordination, Li Ye said there will be a total of 52 stationary toilets throughout the 5.2 square kilometer Expo site, with a total of 6,410 cubicles and the proportion of male to female toilets will be one to two and a half, so queues for the ladies should be minimised.

“Queues to toilets are unavoidable in the Expo site, but the organiser will promise no long queues.

The Expo kicks off in May and Shanghai is set to build 1,039 new public toilets and make around 800 downtown public toilets free for use.

The city will have five public toilets per square kilometer, as opposed to the three that currently exist.
