question about connecting an ejector pump to the sewer, where there is no existing conditioned structure that gravity-feeds:

We have a lot that will be built in a couple years. Lot is sloped, with road and sewer main nearest to the up-hill lot line. The house will built in that corner, and high enough to gravity feed to the main. For the next several years & through construction, we're living in a yurt, placed on the opposite (downhill) edge to be out of construction's way.

The yurt needs a toilet, but it is much too low to gravity feed directly to the sewer. We're familiar with ejector toilets, using one for a basement bath in another property - but that house has its own bathrooms above grade (meaning existing gravity connection to sewer, in a conditioned space, requisite venting etc). Obiously the fixtures flowing to the ejector require their own venting to code, as well.

What are our options to connect to the sewer exclusively from a pressurized / non-gravity line? Can we accomplish this withOUT a (conditioned) structure high enough to gravity feed, housing the vent stack and junction for the ejector's pressurized effluent pipe?

Many thanks!
 
seems this thread got a bit out of control - but if it helps anyone:
  • yes, i'm in the USA.
  • My design has changed a bit (for the longer): 6+ ft rise and 150ft+ run - all diagonal
saniflo rep had to "check with engineering" - but called me back and confirmed that YES the Sanicubic-1 would work fine for this, diagonal and all.

And, i've since answered my original question: I run my pressurized line up the hill, then to "mate" to the 4" (gravity draining) city sewer - it's just a simple coupler - no vent, etc.
The cubic is vented, cant remember if 40/50 or 110mm pipe
