2. Such an amazing database. I just start to enter our new product to the market and this is so useful for us. Thanks for it!

3. Dear Stefan, thanks a lot for sharing these wonderful data links. We would like to add some open source data and reports from these links in to the water network library. Again, thanks for sharing links...:)
