Paris builds pee-proof walls

PARIS, Oct. 29 (UPI) -- The mayor of Paris, who made environmental concerns a major priority, is taking aim at another threat to the city's cleanliness -- public urination.

Paris Mayor Bertrand Delanoe, who made all self-cleaning Sanisette toilets in streets and parks free of charge in February, is turning to a new method of keeping urination off the streets and in the toilets: walls that pee back, The Telegraph reported Monday.

"Le mur anti-pipi" is an undulating wall that features sloping surfaces that reflect urine streams back toward their source, the newspaper said.

"The jet of pee is rather oblique. If it meets a sloping surface it is sent back to the trousers," said Etienne Vanderpooten, a municipal architect who has been working on halting public urination for 25 years.

"It is the case of the arroseur arrose (the sprinkler sprinkled)," he told The Telegraph.
