For those who aren't in the know, an expedient drain field can be made. I know of guys who had hunting camps who wanted a place to drain gray water (not sewage, more wash water).
Hole dug deep enough to bury a 55gal drum. Drill 1" holes all over the stinkin place on the barrel. (or maybe now would be a good time to see how that new rifle works and shoot it all up 
place the now holy barrel in the ground. The hole should place top of barrel at least 2ft down from the ground surface (I think my buddies was 3') Now take the bung off,,,thats the threaded plug on top and plan on spending an afternoon doing the most boring job ever. Placing a pipe over hole into barrel and filling it with 1/2" stone. This may take a while. Fill barrel almost to top. Thread pipe if you haven't already to the top of barrel that will stick up past the surface. fill back in with any left over stone around endges of barrel and then fill hole with dirt. These guys had pipes running from camp sink into this "drain field"
I suppose a slightly bigger one could be made, but these weren't used on any type of constant use basis. Heck the water that these ever saw probably never added up to more than 50 gallons in a weekend, so plenty of time to leach into the ground until next month or longer till hunting again.
Yes, the township REALLY frowns on this, but in a SHTF scenario do you think the building inspector is going to see if you have permits? He may very well be in the next camp over doing the same thing!
hope this helps Why not try something like this.
Dig the hole a bit larger. Make a hole in side of drum 3-4 inches from the top for the sewer drain pipe. DO NOT FILL BARREL with rain rock. Place barrel in hole and backfill AROUND barrel with rain rock. Cut second hole in top of barrel say 8-10 inch diameter. Position lid over this hole with loop handle. Position 2-3 5 gallon buckets with bottoms cut out over hole in top of barrel. Continue backfill of barrel with rain rock to say 4-6 inches shy from top. Backfill rest of barrel and CAREFULLY around 'tube of buckets' ACCESS PIPE. Make a lid/top for AP. Park a TWO MAN ROCK or large planter over ACCESS PIPE to disguise it. As time goes by and barrel fills with sewage move rock, pull off barrel lid and drop hose for waste discharge pump to transfer waste to portable (wheeled tank) and dump at undisclosed location some distance from your camp. (I realize there are some 'holes' in my logic here...just another idea to contemplate.)
Theoretically why not bury 2 barrels. Design/build as you would a "normal" septic/drainfield with 4" sanitary pipe lines backfilled with drain rock. Rent a small Kubota type backhoe and do excavating yourself. Preposition 5 yards drain rock close to jobsite. Camoflauge rock pile. People will often steal from crush/drain rock piles and think nothing of it. There is a fiber type cloth available at Home Depot type stores. Lay this material down on rain rock before backfilling with dirt. Otherwise over time your drainfield becomes compromised with dirt/rock mix. This material is inexpensive and has a long life when buried.
