Installing a Force Main inside a larger pipe/sleeve

Installing a Force Main inside a larger pipe/sleeve

(OP)
I need to run a small (2") sewage force main up a new 600' private subdivision road. If the Town has an issue with the FM being above the water main could I offer to sleeve the FM in a larger pipe for the run? Would the extra space inside the sleeve leave too much room for the pipe to move around while the pump is running and possibly cause a break that wouldn't have occurred if it was direct buried?

Thanks,
Greg

You would use spacers in the carrier pipe.
I'm not sure this is allowed in most of the US, though, even encased.

Agree with jgailla on the spacers.

You will need to contact the water and sewer agencies in the project area to determine their requirements. The typical requirement for horizontal separation is 10 feet.

Is this for a grinder pump? Our regulations require 4" min diameter FM from a pump station. If for a grinder pump station, check with your regulatory agency and see if a continuous HDPE line would be acceptable; basically construct the FM to watermain standards. Definitely check with the local authority and review your state's standards.
