Lake Tai is approximately 2,400 square kilometers (km2) and an average depth of 2 meters. It is the third largest lake in China, while is the most important in terms of population density and contribution of the basin to national GDP. The Lake Tai Basin is within three provinces (Anhui, Jiangsu and Zheji-ang) plus the Shanghai Administrative Region (Figure 1). The lake surface is within two of these – Jiangsu which has 90+% and Zhejiang which is a small slice along the lake’s southern boundary.
Some of Mr Huo’s observations at the meetingThis can improve government functionality to serve clients (eg consultation, advising, factsheets, guidelines)In SZ their practice is not only one department, they can provide consultation services, can help raise awareness, can establish partnerships between companies and government for better working relationships. From the fact sheet we have seen this morning, we have learnt that SZ is improving their capabilities and functions in servicing clients. Regarding methodologies – can be applied to a lot of other industries. So this is not only example for one industry but can play important role for other industries. This is not only a good example for SZ but for neighbouring cities in HZ and promote over China. The government should also promote and issue more regulations to better regulate industry – how to categorise clients, how to collect; how to recycle. Having a private company involved is a good way to promote the process. I think SZ has been ahead of most others. Better improve our management system – reforms to make it more scientific, more integrated. Need better coordination between departments. We were very impressed by this in Australia. We should also learn from you.

Lake Tai Water Pollution Treatment Project Nigel Murphy Project Director, Earth Systems
Lake Tai (or Taihu) Lake Tai (or Taihu), is the 3rd largest freshwater lake in China, borders Jiangsu and Zhejiang provinces (southern part of Yangtze River delta). The total area of Lake Tai is about 2,338 square kilometers (about 902 square miles), with an average depth of 2 metres. Lake Tai is connected to the renowned Grand Canal. The lake is also the origin for a number of rivers. The lake provides water to 30 million residents. In recent years, Lake Tai has been increasingly polluted due primarily to rapid economic growth and increased population in the basin area.
Water Crisis in Lake Tai Wuxi City Yixing Suzhou City Lake Tai City Huzhou City (Google Earth)• Large algal bloom outbreaks in Lake Tai since 1990.• The most significant algal bloom broke out in 2007 in Mei Liang Bay near the Wuxi City, and led to the " Wuxi City Water Crisis”.
2007 Water Crisis in Lake Tai• Water quality worse than Class V of the Surface Water Quality Standard (GB3838-2002).• Tap water supply in Wuxi City had to be temporarily terminated due to the crisis.
The Lake Tai ProjectProject Budget: $AU 2.6 million (Includes extensions)Duration: 2009 – 2012Activity Objectives:• Contribute to successful environmental governance mechanisms at Municipal, Province and Basin levels.• Assist greater use of science-based planning, management and interventions to support lake and river basin management to improve lake conditions• Contribute to a substantial decrease in the frequency and intensity of algae blooms as a result of specific and modern IRBM, science and management technologies.
The Lake Tai Project• Project (and ACEDP) Outcomes – Policy influence – Enduring Partnerships – Capacity Building• Project approach - Information sharing and capacity building to assist the Chinese partners in deciding their future assistance needs and activities.• Extension approach – Collaborative demonstration exercises which if proven successful will be adopted / promoted in Government policy.• Implementing Partners: National Development and Reform Commission (NDRC) and AUS Lake Tai Cluster

Some Key Achievements To Date• Algal bloom control and management knowledge sharing between Australia and China.• Providing lessons (both positive and negative) regarding the Australian experience in river basin management.• Sharing structures for cooperation between government, community and industry.• Developing applied strategies and training for waste water treatment plant optimization for nutrient removal.• Developing applied strategies and training for the management and modelling of non point source pollutants.• Building long term relationships between Australian and Chinese institutions in water and basin management.
Key partnerships and achievements• Improving the Liquid Discharge Pollution Framework

Lake Tai Project Learning• Lake Tai reflects a complex problem with no magic solution!• Many of the issues are well understood, the difficulty is coming up with solutions that are socially acceptable.• Good science is not enough, solutions need community and political will.• Sharing information and transparency assists outcomes.• Many of the issues and difficulties are common across countries.• Establishing governance structures and responsibility is important.• By sharing experiences and identifying best practice examples we help, support and assist each other.
