I plan on installing a septic tank for my garage before the snow sets in on us. my biggest question in my garage is elevated roughly 20 feet higher than where the tank and leach field will be. the distance from back of the garage to the level ground is 25-30 feet. Ive read on zip-sagging the pipe down the hill to slow the water speed but im not to keen on that idea in fear of more clogs. does anyone have any input or ideas on this topic? I know many folks on here have installed septic's so bring on the ideas please.

Not a septic expert, but when I asked one about running a line down a steep hill, he said that the whole, "liquids outrunning the solids" thing is a myth. Your concern might not be necessary.

that's what I was mainly interested in. its not the main bathroom so I don't expect many solids to go down in. a lot of liquids will be going down the pipe so even in some solids get hung up they should be swept away shortly after.

I would ask your contractor.
But I see no reason not to run it straight with a clean out at the high point.
(Just in case.)

As mentioned, check your local code folks. In our area, we are not allowed to have a separate septic system on the same residential lot but do need a reserve field in waiting in case the main house field fails. For my new garage, the authorities require a separate holding/pumping tank which takes the waste from the garage and pumps it to the main house field, bypassing the main house septic tank. You may be faced with a similar requirement.

All the language about not exceeding a certain slope with piping was removed from our code. It was disproven that liquids would outrun solids and the pipe would plug.
