In Beijing, the safety of drinking water for the Olympic Village will be ensure by a control system, developed by the Research Center for Eco-Environmental Sciences and the Chinese Academy of Science. The system will neutralize several chimical and organic polluants, using a variety of technologies, including catalytic oxidation technology and reactors.

A model for all of China

The main concern is what kind of city environment athletes will find? What sort of water will be supplied to the public? Those questions are not recent as they had been asked years ago, when Beijing knew it was choosed for organizing the 2008 OG. But this concern emerged since few weeks because of the worry of sportsmen. Some are afraid of the environment conditions in which they are going to compete (polluted air and not potable water), thinking it could have impact on their performances. But China wants to show to the world its credentials and the BOCOG has invested a lot for that: the Olympic Games would be an environmental model for Beijing and China. Making “Green olympics” is one of the 3 goals the BOCOG has set up.

New water facilities

In November 2005, the BOCOG and the United Nations Environment Programme signed a Memorandum of Understanding, which aims to ensure that the OG will take place according to environmental account, especially for water quality improvements. The city of Beijing has made great investments for updating and building water and wastewater treatment plants: in the urban aera, 15 wastewater treatment plants (WWTP) have been rehabilited or built. 9 of them have been upgraded with a tertiary treatment process recycling water.

Those upgrades are one of the answers to the water shortage issue in Beijing: the recycled water will be used for non-potable purposes. In addition to those infrastructures, about 4000kms of sewer pipes will be laid. Thus, the sanitation system will improve the wastewater collection that expect to reach 2.5millions tons of wastewater discharge in a day, only for the urban aera of Beijing. In 2006, officially only 52% of wastewater wre collected and treated, but thanks to the municipals WWTP, this rate is expecting to raise to 90% with the treatment of more than 4 millions m3/day. 50% of this water will be reused for irrigation and ensure the water supply of ponds and lagoons in the Olympic village; formally, the rate barely reached 15%.
