Hello, colleagues!
I need your help with the design of pressure sewage pipeline for Camp in Africa (scheme is attached);
I am going to install 4 WWTP 200m3/day each.
I plan to use PVC pipe and a lot of Lift Stations.
Have no experience with pressure line so big scale.
Next issues I got:
1) Which materials are better to use and which type of connections?
2) Is it accurate Lift Stations locations on the Layout?
3) Any comments are highly appreciated!

Link for Layout in good quality:

To make our discussion more clear I attache simplified scheme here with 4 buildings and 3 lift station. I know that 280 persons and 5 lift station are feasible. But does it make sense if you have 1000 persons, 5000 persons and 10 lift stations or 50 lift stations? Can pump of the lust lift station handle with effluent?

You're probably better off asking your questions on a civil engineering forum. What you're asking is pretty much out of scope on this forum. This sub forum deals primarily with mechanical engineering.
