Dear all,

thank you all very much for your replies. In fact I am not looking to build a vacuum sewer. I m conducting research on the critical factors for successful or failed installation examples. Such factors that affect planning, installation, operation and maintenance.

What are the limiting factors of the vacuum system? (e.g. can VS be implemented in large urban areas instead of gravity systems?)

Why isn't it implemented more often?

What are common sources of failures?

What are bad and good examples of vacuum systems around the world?

Thanks a lot for your input

Marc
