People can compost there own septic sludge to save on pumping there septic tanks. Use a sump pump to pump the water out then get in your tank and shovel the muck out into a wheel barrel or lawn tractor trailer. Mix the sludge with sawdust and dump in your compost bin cover with grass clippings or hay or your garden debris.
Staff note (Burra Maluca) :

People die after entering septic tanks - please read Douglas Alpenstock's post and take heed!

Wow Robbie!!! You really need to find a few new hobbies... LOL!!!

On a more serious note...

You really have to be careful about this. Some folks may have an elderly person or relative contributing to that septic sludge or composting toilet. If so, are they on a plethora of meds? Is anyone else contributing poop or pee on meds of any kind? Cus those will concentrate in that septic sludge or in the compost from a composting toilet. And some of those could uptake into plants and leach into water tables. There is a lot of thought that needs to go into grey water and humanure. Some meds can kill plants and soil biology. Sometimes it’s better to hire a septic truck to transport it to a treatment facility equipped with the technology to make it safe.

Now if your poop and pee is as pure and clean as the driven snow, and you like the night life, and like to boogie, and happen to be a thrill seeker willing to brave crawling into a full septic tank... Then by all means, shake yer groove thang and grab a shovel and a cloths pin off the line... But me? I’m gonna go fishin some place that has clean water. I got shit to do that doesn’t involve shit to do... LOL!!!

(I hope you had as much fun reading as I did writing. I’m all for composting, just wanted to add that safety consideration)

Good luck!

***Time Out: Big Fat Safety Moment***

A septic tank is a confined space, and by definition and design an anaerobic environment. People die in these places, out of ignorance and stupidity. And somebody else will have to risk their safety to pull them out. If that is a safety professional with supplied air, well and good; but usually it's your buddy or partner trying to rescue you. And now there are two fatalities. It happens all the time.

Even if your plan in life is to "compost in place" at the bottom of a poo pit, be advised that you will probably put other people in danger. That is not cool.

A great big fat AMEN to this public safety announcement from Mr Alpenstock...

Excellent catch on the safety aspect Douglas!!!

Well pumping out your own septic tank and discharging on your property is illegal.  So .... you have to understand what your doing , be careful and sneaky.  First thing septic sludge is not very sludgie or thick.  Yes the solids settled in the first compartment is thicker but pumpable.  The problem is the water and doing it safely.  First thing what type of soil do you have?  What is the value of the perk test.  Fast? very fast .,, very slow??  

I pumped out my second compartment so low that was down to the connection to first last year.  So really pumped out majority of volume, so left about 100 -150 gallon in 1st chamber.  Pump flow rate was greater than anticipated so covered a larger area than I thought so was a bit unprepared.   I have a very fast perk so liquid volume was gone very soon after I stopped the pump.  Left a very thin layer on ground.  Again your not dealing with a lot of solids.  I ended up having a bonfire which quickly got rid of smell and all the solid residue.

This year have prepared an area that will take almost entire volume.  Will check after a couple of minutes to check how fast draining and will turnoff pump if required.  Haven't decide if will burn or just cover with soil with a couple of shovel fulls of composted cow manure that is full of red wigglers .  

Pumping, If you use a solids handling pump I don't think you will have any issues pumping out everything.  Maybe a hose to get the thickest sludge moving and dilute at the bottom of the 1st chamber.  Also to get the bit in the corners.  If want to use conventional pump then could use an educator  but then have a lot more water to deal with.

Overall what are you doing that is different than the septic field ?  I'm putting the fluid right beside the end of my field at almost the same elevation.  My pipes are about 14" -16" below grade.  The difference is that volume is over an hour rather than over 4-5 days.  The solids are going to be trapped by the soil in the first couple of inches.  As long as those solids are disposed of properly ( burn or cover) not really a difference.  The water volume as long as good distance from well or any water course should also be good.

adding - of course never go into tank, wear gloves , wash off pump back into tank, flush out pump and hoses when done to your disposal area.
