100' sewer drain

Just buy 10 sections of 4" sewer pipe, less than $100. They slip together and if assembled properly, no glue needed.

The correct slope is 1/4 inch per lineal foot or about 2 inches per 10 feet. I can't imagine how the sewage is going to make it 100 ft. along the ground.

Purchase the sewer solution. With water pressure 100' will be no problem! You can hook it up to PVC pipe and no stinky slinky. One of the best things I have purchased for the motor home for around a $100.
Good Luck

I would make one out of a garbage disposal pump as gboop suggested. Once finished you can flush with water to clean everything up and the water hose can still be used to water the yard... do not drink from it.:B

If it's a long term situation you might consider a maceration pump. They make pumps that mate directly to an RV sewer drain, and then I think they pump through a garden hose to the final destination.

I agree whole heartedly a 3" sewer hose over 100' long without any slope and you need to consider shovels for the clean up! I had a unit that used water to pump the "stuff" into a standard 5/8" water hose! Connected to standard sewer hose outlet, and worked great! Downside was you need to have two dedicated hoses to operate, do not mix them up with drinking hose!

The 1/4 per foot thing is absolute minimum and that's with smooth walled sewer pipe. A "stinky slinky" with that minimal slope over 100 feet? Ugh.... Better get some really thick rubber gloves.

As someone else said, you'll be wishing you'd laid out the extra money for the pump and macerator. The situation you are describing is exactly what they are designed for.

Rusty,

Left to right on the blackboard and downhill in real life!

I have a sewer solutions. I connect its 10' hose to 50 additional feet of 1"PVC that I slip together temporarily and it goes from the outlet under the trailer to the front of the garage into the garage and UP 48" to the washing machine stand pipe. 100' on the flat should not be an issue. I LOVE not having to worry about finding a dump station as we dry camp a lot.
