Hi All, I am in the process of planning on building a cabin on a rocky riverfront, mountain location where digging down a septic field will be impossible so I am investigating the idea of pumping sewage up. I'm talking hundreds of feet. Any comments , ideas??

Every foot of rise equals about .5 psi pressure needed. So 200 feet up requires about 100psi at the bottom just to make it to the top. You may need one or pumping stations along the way to make it to the top.

No one here has a clue where you are so have no idea what's required in your area.
Any place I've ever lived no home owner should be designing how to do this.
I'd start by contacting a local soil scientist, they can design the whole system with code approved plans needed so you can get bid on having it done.
Around here just the plans would be over $2000.00 then you have to have the county approve the plan before getting any bids.

look up sewage lift stations. 200 feet is not that far and they have complete lift systems,
I am pumping about 500 feet and have a dual grinder pump system 1 1/4 discharge. Zoeller has a great line and there are about 3 other type brands - just get grinder pump

Grinders are not recommended for septic. The solids and liquids need to be able to separate in the tank. Grinders are typically used in forced main sewers. Check with your local health department and they will point you in the right direction. If you have to pump that distance to a septic tank, you will need to use a 2" solid handling sewage pump. If you are dumping into a sewage tank outside the house then pumping into an effluent tank somewhere else then you will need an 1-1/2" discharge effluent pump. Below is the formula to determine TDH. But depending on what your needs/codes are depends on the GPM requirements for your area.

RUN + 50 (to allow for friction loss) = XYZ
move the decimal place back 2 places X.YZ
multiply X.YZ BY 2.06=Y
Y plus LIFT = TDH (TOTAL DYNAMIC HEAD

EXAMPLE:
8 FT OF LIFT
120 FT OF RUN
120+50=170
1.7X2.06=3.502
3.502 + 8=11.5
11.5TDH

Hi Sheplmbr
OK I have a question for you. I am pumping to a sewage line - uphill. I am using dual grinder pumps. The issue I am having is based on dual pumps pumping once every two days for five minutes, I believe that the pumps are only pumping less than 15 hours per year.
I have issues every year with the pumps melting the pvc pipe, continuing to run. Yes the alarm goes off and the light goes on. If we are out of town those alarms do no good.
What type of switch can we use that does not go bad?
The zoeller panel does not stop the pumps if they go for 10 minutes- what type of control panel takes care of this and stops the pumps? Ten minutes is the max amount of time it would take to empty the 1800 gal tank if it were full.
What type of preventative maintenance can be performed and how often?

Thanks for your reply

Are you on a force main sewer?
You should have a thermal overload on the pumps. Are they on demand or timed?

Make sure they are sized properly. Also if they are on demand, check your float sensors to make sure that they at the correct height. Also double check your amp load. In your case it may be prudent to get a reputable company out to check it out. A lot of times I get contractors that should know better but don't. They will just throw anything in.
