Hi peterprocopio,
Start with [url] www.aermotorwindmills.com/zoellersumppumps.htm [/url] and/or put "effluent pumps" into a search engine.I have experience with Zoeller pumps in a hospital application which had to pump sewage 10' up to the septic tank.These rarely jammed and were easy to remove and work on when necessary.

If your installing a full bathroom you will need an influent pump, these grind and pump out solids, an influent pump only takes away liquids, and will plug on solids, cigarette buts, condoms... etc.

If your adding to the plumbing load of your original septic tank you should look to see if it can handle an increased load of your new bathroom group, it may be just as easy to replace your old tank, lower it, and take a new sewer line out of the house low enough to serve the basement.

Grinder pumps are very expensive, and in this case you will need a holding tank inside your house as well.

I realize this wasn't your question, but one of the responses mentioned that you will be adding another load to your septic tank (no pun intended). To keep your septic tank and drainage lines clean and to keep from having to pump your septic tank, you may want to get some Super Power 7 from the 'Biotech Store' at www.shopEZ.unfranchise.com.
