A great way to deal with dog poop if you have multiple dog's, or are simply running out of space in your back yard to put it all.
Step 1: Find a Bin
Find a good plastic bin. I used an extra green compost bin I had laying around. you could use a garbage can, or what ever you got that has a good solid lid.
Cut the bottom out of your bin. I used a jig saw. you can use anything you think will work. shears would cut a regular garbage can easy. I had to use a saw because my bin was heavy duty hard plastic.
Step 3: Drill Holes
Drill holes with the biggest drill bit you can find that will fit your drill. drill about a quarter to half of the way up the bin from the bottom.
Step 4: Dig a Hole
Dig a hole wide enough for your bin size and deep enough to be able to sink the bin about three quarters of the way into the ground. now fill in around the outside of the bin snuggly with dirt.
Step 5: Finished
There you have it. dump all your dog poop into the bin and keep the lid shut. I got a hold of some active house sized septic tank enzyme and added it to mine. A very small amount. I put a table spoons worth in mine to help speed up the breakdown of the dog poop.
Every so often get a bucket full of nice warm water and poor it into your dog poop tank. It will help keep things going.
You want the decomposed poop to slowly leach into the soil around the bottom of the tank. That is why you cut out the bottom of your bin and drill holes 1/4 to 1/2 of the way up your bin from the bottom. acts as mini weepers.
If you want to take things further another step, you could dig even deeper and fill the bottom with gravel and sand. maybe 2' or 3' worth to aid in drainage. Mine works fine without that step.
Depending on how many dogs you have, decides on how big of a tank bin you need. I have 2 dogs. so mine isn't that large. if you have more then 5 dogs, you are gonna wanna get a very large bin.
