7th World Conference on Sport and the Environment - International ...

Report
In 2006, the city consumed 360 million cubic metres of recycled water, 10% of the overall annual water
consumption.
In 2006, a recycled-water irrigation zone of 200 thousand Mu (13 thousand hectares) was built in Da Xing,
which utilized recycled water of 100 million cubic meters annually. In 2007, Project to Divert Reclaimed
Water to the West Part of the City was completed in No. 6 Water Supply Plant and provided 80 thousand
cubic metres of reclaimed water each day to Gao Jing and Shi Jing Shan Power Plants, or 30 million
cubic metres annually.
So far Beijing has built 6 reclaimed water plants, with a daily production capacity of 370 thousand
cubic metres and reclaimed water pipelines of 380 kilometres. The application of Membrane Processing
technology has ensured the safety and quality of reclaimed water and provided technical guarantee for
promotion and dissemination of reclaimed water utilization. Olympic Lake has used high quality reclaimed
water produced by Qing He Reclaimed Water Plant.
Beijing plans to use reclaimed water of 480 million cubic metres to fulfill 50% of its committed goal
this year and 600 million cubic metres of reclaimed water in 2008. Reclaimed water is important water
resource for agricultural irrigation, ecology of rivers and lakes, industrial cooling and other purposes.
V. Water Environment Construction in Olympic Stadiums and Gymnasiums
All stadiums and gymnasiums are equipped with water-saving facilities to process all waste water. Water
system in Olympic Lake uses high standard reclaimed water processed with membrane technology.
They also adopt reclaimed water utilization technology which utilizes 4.69 million tons of reclaimed water
each year, rain water collection system which utilizes 1.05 million tons of rain water each year, and water
infiltration system of more than 1 million square metres to replenish and conserve underground water.
VI. Sticking to Ecological Treatment of Rivers and Completing Treatment
of Backbone Water Systems
Beijing has 500-kilometre-long rivers within the Sixth Ring Road. But water in some watercourses was
black and smelly because of the direct inflow of waste water; the poor water environment quality in rivers
and lakes was the biggest headache for urban Beijing. To solve the problem, Beijing has worked out the
work strategy which specifies river treatment as the fist step in pollution control, to clean the water quality
as the main goal in rivers and lakes treatment. It has been investing on managing several rivers each year
through preventing and controlling pollution of discharged waster water into rivers. The problem of direct
inflow of waster water into rivers has been basically solved and the history of discharging waste water
into urban watercourses was ended.
During the process of river treatment, ecological water treatment technology was adopted to restore
diversity of aquatic plants and animals in watercourses. More than 60 types of aquatic plants are planted
such as reed, cattail and lotus and more than 10 species of aquatic animals such as fish and shrimp
(over 50 tons each year) are raised in the watercourses, which have effectively protected the health of
watercourses. Ecological-restoration technologies have also created conditions for reclaimed water
utilization in rivers and lakes.
During the five years from 2002 to 2006, the percentage of watercourses cleaned increased from 15%
to 85%. Over 70% of urban rivers and lakes have reached quality standard, of which 45% are ecological
watercourses. Qing He, Liang Shui He and Tu Cheng Gou rivers have gained clean water. In 2006, while
environmental water consumption from urban rivers and lakes was increased to 180 million cubic metres
and clean water supply was less than 100 million cubic metres, Beijing managed to keep good water
environment in urban rivers and lakes.
In addition, Beijing has also taken measures to guarantee good tournament environment for Olympic
Triathlon and Aquatics sport. The water quality has already met the requirement for matches. Meanwhile
it has also improved the surrounding environment of Shi San Ling Reservoir and Shun Yi Aquatic Sports
Field.
In nine months time, the 29th Olympic Games will be held in Beijing. To host a unique and high standard
Olympic Games is the dream of each Chinese. Beijing Water Authority will follow the requirements of
