Value in the full water cycle Process Water Boiler feed Water Industrial customer Cooling Water Waste Water NethWater focus on the power & chemical industry: Process water (eg: Desalination) Waste water treatment (eg: MBR) Water (Re)use Technology (eg: UF) Water source management Also in Northern Europe water stress is experienced, for example: London City The local rainfall of 600mm/year results in availability of only in 265 m 3 /cap/yr *. This is less than in Israel. Water reuse will increase the availability of water for the urban supply and therefore good water management is integrated into EU legislation: EU Water Frame Directive 2000/60/EC Promoting sustainable water use, protecting available water sources * Source: Planet Water, RWE Thames, London, UK - 2003 7-6-2010 16

Shaanxi Province Shenmu Xian 7-6-2010 33 Water management Yellow River The Yellow River Runs Dry In 18 out of the last 26 summers the Yellow River has run dry further and further upstream for longer periods of time. During the summer of 1998, the river failed to reach its mouth at Bohai Bay for over 250 days.

Overall conclusions Global urbanization + industrialization demands good water source policy, legislation and control. Water management will integrate water demand, water availability & sufficient water quality. Turning effluent water into a valuable water source for the Industry. Technologies for water treatment and reuse are available, proven practise and a sustainable environmental solution. Cooperation between different parties in the water cycle is required for maximum efficiency: Industry: end-user of the water; Municipality: supplier of the water, waste water and regulator; NethWater: water utility operator can be the integrator of the parties via BOT contract: Investment, Design, Construction and Operation of the integrated water (reuse) treatment plant. 7-6-2010 47 Overall conclusions NethWater provides integrated water solutions: integration of know how, designing, engineering and operation; BOT is the business format of choice of NethWater; In case you are interested in our services please contact and meet Mrs. Cathy Feng of Evides China in Beijing. 7-6-2010 48
