AN option to import a fleet of super-dooper pooper scoopers to suck up smelly calling cards dropped by Hong Kong dogs has been spiked after a government study. The French prototypes consist of a powerful vacuum cleaner and a water blaster attached to a motorcycle, which is ridden along roads and footpaths after the dogs have done their deed. But officials from three departments, Transport, police and Urban Services, agree that Hong Kong's fouled footpaths are altogether too crowded with people to accommodate the two-wheelers. It has been decided the interests of public health would be better served by keeping motorcycles off the pavements. The territory's black spots for dog droppings are Mongkok, Western and parts of Wan Chai, according to the Urban Services Department. ''We are talking about a vacuum cleaner on the back of a motorbike. The driver points a nozzle, sprays water on the soft faeces and then sucks them into a container on the back,'' said Wong Siu-wing, staff officer (cleansing) for the Urban Services Department. Mr Wong's staff contacted the manufacturers in Paris and received illustrations of the model and its specifications through the French Consulate. ''I also asked for comment from police and the Transport Department but they were not in favour because most dog faeces are on the pavements,'' said Mr Wong. ''We have finished our assessment and found that in Hong Kong it's not feasible because the pavements are too crowded.'' Instead, plans are in the pipeline to introduce containers full of plastic bags so responsible dog owners can help keep Hong Kong clean. The containers would supplement about 200 public ''dog toilets'' in the territory.
