What is a dog poop septic tank and who needs it?

A dog poop septic tank utilizes a formula composed of natural and non-toxic enzymes to break down solid canine waste into an absorbable liquid, similar to the process that occurs in home septic systems. 

This process purifies the substance through microbes present in the soil, offering an effective way of disposing of dog feces without any hazardous components.

What is a dog poop septic tank

For people who let their dogs do business in their garden, a dog poop septic tank could be the ultimate answer to your problems. 

Not only will it make sure that the waste is disposed of properly, but it can also help save time and energy on cleaning up after your pup. Plus, you won’t have to worry about pesky neighbors complaining about the smell!

Now, let’s get into the how-to of setting up a dog poop septic tank.

How to set up your DIY in-ground dog poop disposal system

Before you get started, make sure to have all the essential materials and tools within arm’s reach. This includes a shovel or spade, a 5-gallon container, some small stones or gravel, and of course dog poop septic tank enzymes.

Dig a hole as deep as your container

To start, dig a hole in your backyard that is slightly larger than the measurements of your container. This extra space will create room for stones used to promote additional drainage. 

Make sure that your container will eventually stick out at least 2 inches above the ground.

Drill drainage holes in the container

To ensure that excess precipitation doesn’t accumulate in your container, use a power drill to create several small holes near the bottom and side of it. Make sure these openings are just wide enough for water drainage but not big enough for solid waste to escape as well.

If you would rather purchase a ready-made septic tank, there are tons online with thorough installation guidelines. Doogie Dooley is widely renowned for its premium quality tanks and their products come paired with user-friendly setup guides.

Place stones at the bottom of the hole

Place a layer of small stones at the bottom of the hole. This will help to promote an even distribution of drainage from all sides. 

Make sure that the stones are clean and free from any potential contaminants.


Place your container in the hole

Once you have completed drilling drainage holes, place your container into the hole that you just dug. Line up the edges of both the container and the hole so that they are even with each other.


Fill in the extra space around the container

Using your spade or shovel, fill in the extra space around your container with small stones to help promote drainage and prevent runoff. Make sure that all sides of your container are completely covered by stones. 

The remaining space can be filled with dirt to help keep the stones in place.


Add enzymes to your container

Once you have completed steps 1-5, it’s time to add the dog poop septic tank enzyme. This will help break down solid canine waste and prevent bad odors from accumulating in your yard. We recommend Doogie Dooley waste tablets.

Things to keep in mind with a dog septic tank

After building your own septic tank, there are a few things to keep in mind to maintain a healthy and odor-free environment.

Spread out the waste disposal

To avoid a potential clog in the system and guarantee even distribution of discarded materials, it’s best to space out waste disposal over several days instead of throwing them all away at once. 

The enzymes are only able to process a certain amount each time, and this method will ensure that they can handle the weight more easily.

Change the enzymes regularly

Enzymes will degrade over time so it’s important to change them out every few weeks. This will ensure that the waste in your tank is broken down properly and prevent any bad odors from seeping out.

During winter the process takes more time

Due to cold weather, the enzymes will slow down their process during winter. This means that it might take longer for the waste to break down and for bad odors to dissipate. 

Be sure to keep an eye on your dog’s septic tank during winter and adjust the enzymes accordingly.
