Near horizontal to sewer - macerator waste system?


I am thinking of putting a bathroom in my workshop at the back of my property. The problem I forsee is the near horizontal run the sewer line would have to be - there is some drop, probably just a couple feet over the approx 200 that would be the length of the run.

I have been reading on macerator waste systems, which help - but still need the normal gravity drop to the sewer. Is there such a thing as a macerator waste system with a pump to allow the long near horizontal discharge?

I would be installing a toilet, shower, hand wash basin, and a utility sink. the usage and volumes would be low.

All suggestions to my problem are welcomed!

Thx!

I was thinking you would have to put in a vertical zigzag system, with normal slope down to a holding tank in the middle of the run, and the macerator pumping the sewage sharply upwards several feet at that location to the next section of sloped pipe (or maybe two macerators and holding tanks, at the 1/3 and 2/3 marks respectively).

Ayuh,... An inch in 10 feet is sufficient fall,... Sounds like it'll work Just Fine with a 4" hard pipe run...

"Is there such a thing as a macerator waste system with a pump to allow the long near horizontal discharge?" Yes. We installed one at a friends "farm" (9 acres) about two years ago. He wanted a room for toilet, shower, hand sink to clean up after working horses. This unit had a 230+ foot run of 2" pipe back to his septic tank, per the instructions from the local plumbing suppy house he bought it from. It has worked fine since installation. Part of this piping was actually uphill, but the plans from the maker of the system stated that this would work within certain parameters. IMO-Bondo is correct also, 1"/10ft. should work for your system. Sewer lines are not usually set up so the waste runs through very fast. Some settling and waste degradation takes place within these pipes. Good Luck, David
