BEIJING, May 16 -- Shanghai aims to limit
residential water consumption per person to within 0.155 cubic meters a day by
2010 and revise the quota for business and industrial water users to improve use
The Shanghai Water Authority said yesterday
it will employ a new pricing system setting lower rates for frugal water use.
Other measures include education and upgrading
water-consuming facilities like flush toilets. Old residential flush toilets are
a major cause of waste.
The authority launched a weeklong water conservation
campaign running until Saturday. It includes displays of government conservation
measures and spot checks of big water users.
The new pricing system will set quotas for different
rates, to encourage all users to be frugal. Details of pricing system were not
yet disclosed, but officials said it's likely to go into effect this year.
"It is crucial that a water conservation mechanism
allows economic measures to play a major role," said the authority's water
Currently the residential water consumption per
capita per day is 0.165 cubic meters. Most home water is used for flushing
toilets and taking baths. It is estimated that urban residents use 30 percent to
40 percent of their water to flush their toilets.
Toilets meeting old standards waste a lot of water,
flushing away an unnecessary amount of water. Old toilet tanks contain 13 liters
and often leak. The current standard is 9 liters.
The government has upgraded 68,000 toilets in old
apartments at no cost since 2003. But some 600,000 homes are still using
inefficient toilets that waste 24,000 cubic meters of water a day.
Officials are also preparing to revise water quotas
for different industries and businesses to make the quotas more practical. The
current quota was issued in 2001 and doesn't satisfy current conditions and
requirements for water saving.
Shanghai will closely monitor heavy water-using
industries, such as power generation, metallurgy and chemical companies, which
consume more than 20,000 cubic meters of water a month. More recycling will be
Forty-five major water users will be tested to
calculate a reasonable water consumption level.
Shanghai used nearly 3 billion cubic meters of
tap water last year, an increase of 4.8 percent year on year, with the peak
daily demand approaching 10 million cubic meters.
