Dear Marc The use of vacuum ...

Dear Marc

The use of vacuum system is a good choice, but some aspects are relevant, specially security, materials and energy.

Do you have some experience in vacuum practices?

 

I think that there are two ways that these systems can work: 

(1) I think that you want transport the waste water using some system that use a gradient of pressure. You need provide energy for generate the pressure gradient (the energy that need  the vacuum pump), you need provide security (avoid implosion risk) and adequate materials (avoid loss of gradient pressure). 

(2) you can develop a sewage depuration in situ system and transport clean water for prepare these water for other uses. In this second case, if you want we can collaborate and search some funds (public or private) for the design of these system.

Dear Pedro,

thanks for your reply. I m still at the beginning of my research so I mostly have theoretical knowledge of the VS. I ve seen a couple of systems here in Germany from Roediger.

(1) Yes, I agree. Pressure gradients are inevitable in this system, I guess that is one factor limiting the vacuum main to approx. 4 km. And the need for electricity and adequate materials make this system quite advanced and pose difficulties on its management. I do believe though that its benefits in many cases outweigh the gravity system which also requires energy for lifting pumps and material failure does just go unnoticed (e.g leakage).

(2) This is a great idea. I was wondering about this as well. Maybe we can discuss this as well. Please send me an email: marcbeckett@gmx.de
