10.63 The solution: Founding of a cooperative in 1899
9.19 8.14 • Cooperation of public law
• Members: Municipalities, industries, mining companies
• Self-administration and self- responsibilty
• Non-profit
• River basin management: water, waste-water, ground water, flood protection
• Today largest waste-water
