Despite introducing water from
the Luanhe River and other sources, Tianjin, with an average annual
rainfall of 575 millimeters, has only 370 cubic meters of water
available per capita, which is far lower than the alert of 1,000
cubic meters recognized internationally.
The sustained drought in the
Haihe River drainage area since 1997 forced the city to divert
water from the Yellow River in 2000, 2002, 2003 and
2004.
The water shortage has taken
something of a stranglehold and is affecting development and the
daily life of the city. However, the shortage has seen various
water-saving initiatives adopted in the area.
The city has released a string
of regulations such as the Water-saving Enterprises Standards and
Regulations on Water Utilization Plan of Construction Projects to
prevent enterprises from misusing water.
In the Tianjin Development Zone,
the reuse rate of water utilized by industry reached 90 percent
last year. As a result, a yield of
10,000 yuan output value only consumes 6 cubic meters of
water, only one twelfth of the national average level. The
Tianjin Alkali Factory reduced waste discharges by 90 percent by
using seawater for cooling purposes. And the Tianjin Steel Company
reuses 97 percent of their industrial water.
The government is also promoting
public awareness of conservation through the mass media and by
starting programs identifying water-saving stars and blasting the
"wasters".
"Before the project of
introducing water from the Luanhe River, we had to drink bitter and
salty water and we know that the water we use nowadays is
hard-earned and are fully aware of the importance of saving water,"
said Liu Jianrong, a resident in Baodeli community in Hexi District
of Tianjin.
In Liu's neighborhood,
reinstallation of water-saving facilities was completed last year.
All the 9 and 12 liter flush toilets have been replaced by those of
just 6 liters. And tap faucets sealed with ceramic have replaced
those having secure rubber pads.
"The new facilities are not only
convenient but also water-saving indeed," said Liu. Once suspicious
about the project, Liu is now convinced that it works. It’s
estimated that water consumption can be cut by as much as 20
percent.
To date, a total of 14 old
communities in Tianjin have had reinstallation completed. And
communities constructed after 2001 are all equipped with modern
devices.
Apartments in Meijiang Fangshui
Garden of the Hexi District are equipped with three water supply
systems – drinking water, recycled water and ordinary tap water.
The monthly consumption of Li Shaoqin’s household, one of the local
residents, includes approximately three tons of ordinary tap water
and five tons of recycled water. Since the price of recycled water
is much lower than that of the normal supply, Li now spends less on
water fees than before.
Even so, Li continues to rack
her brains on how to save more water. She uses a twin-tub washing
machine and a double-button flushing toilet, saving water after
washing vegetables for flushing and mopping the floor with the
water flowing out of the washer. "I do this not only for saving
money but also saving water," Li said. Most of her neighbors are
practicing the same principles, she explained.
The saving water is also being
followed through on the college campus. Two years ago Tianjin
University of Finance and Economics introduced systems in public
areas to measure the amount of water being used by
students.
The university provides 150
liters of free boiled water every month and students have to pay
for any extra they require. Students also have to pay for taking
showers on a minute rate. It's estimated that at least 165 liters
of water is being saved each day in the university’s public
bathrooms.
There's also the "price lever"
which encourages residents to save water. The government has
adjusted the price of running water seven times since 1997. The
price of drinking water has increased from 0.68 yuan per ton to 3.4
yuan. Non-drinking water costs 5.6 yuan per ton while water
consumption for special industries costs 20 yuan per ton. The price
of recycled water ranges from 1.1 yuan to 1.8 yuan per ton
according to usage.
