Raise water prices

The pricing mechanism should be used to encourage water conservation in the car-washing industry, says an article in the Shanghai-based Oriental Morning Post. The following is an excerpt:

According to news reports, the car-washing industry uses more than 10 million tons of water every year in Shanghai. By the end of June the city was home to 792 registered car-washers, only 40 of which were equipped with recycling equipment to allow for water conservation.

The recycling equipment, which allows car-washers to save up to 60 percent of the water used, would be appropriate for Shanghai, a city that faces shortages of this precious resource.
