The organisers of the 2012 London Olympics are faced with toilet trouble ahead of the mega sporting event in July.
According to documents obtained from the Olympic Delivery Authority under the Freedom of Information Act, test events at the new handball and basketball arenas were riddled with blocked toilet problems, the Daily Express reported.
Plumbers were called out 32 times to the two test events last summer, including to one lavatory malfunction in the basketball stadium's VIP loo.
Much thought was put into the design of the Olympic Park's thousands of toilets in an attempt to make the Games green.
There are concerns that the green targets might be the reason behind the blocked toilet problem. The loos have water-saving dual flushes, which, when used in large commercial environments where the drainage pipes are far longer and shallower than in domestic homes, are more prone to blockages.
