Piping for lift stations at marina's

[djacks02]

Designing for sewage piping to be installed at a marina that will only be used during the warm months of the year by the members of the club. The concern or question that I have is if the piping is located near the steel wall pilings that extend above water level roughly 4' to grade.
How can you avoid the piping from freezing during the winter months and joints loosening or seperating? Should expansion joints be installed? Should the piping be filled with a recreational vehicle anti-freeze? Please let me know I am curious on how this can be affected.

This sounds like a problem that can only be solved by knowing more details. Why can't you bury the piping? Can you encase the piping in concrete? Is damage by ice in the water body a concern? Can the pipeline be emptied during freezing temperatures? I would think that this problem might be avoided by moving the pipe, but again, we don't know the details.

Regarding freezing of the water inside the pipe...if you can suggest anti-freeze, I would think you can just empty the pipe during the winter. The bigger concern is protecting the pipe from ice in the water outside the pipe.

Contact Eurapipe (part of Tyco) in Asutralia. They manufacture Pre insulated ABS. Not the ABS given such a bad name in the USA but a different formaulation used extensively here for sewage applications up to 800 mm diameter.

the pre insulated material is used in district cooling applications.
