Introduction
Dog waste is a major environmental issue. According to one source, dog waste makes up around 5-10% of the solid waste stream in urban areas in the US alone (Source). In fact, another source states that today US dogs produce more waste than humans did in 1959 (Source). All of this waste can contaminate water sources, spread diseases, and create unpleasant odors if not properly disposed of.
In-ground dog waste disposal systems provide an effective solution to this problem. These systems consist of one or more receptacles installed underground and connected to a biofilter or septic system. Dog owners simply lift the lid of the receptacle when their dog defecates, and drop the waste bags into the bin where they are broken down and treated.
With an in-ground system, dog waste is immediately contained, reducing environmental contamination. The systems are also more aesthetic, keeping waste out of sight. In-ground disposal provides a convenient and responsible way for dog owners to manage their pet’s waste.
Benefits
One of the main benefits of installing an in-ground dog waste disposal system is that it provides a more hygienic and less smelly method for dealing with dog poop compared to simply leaving the waste to decompose above ground (1). Unlike leaving waste on the lawn or open ground, an undergraound system helps contain any odors and prevents the feces from spreading germs across the yard. Research shows visible or surface dog waste can cause grass die off and unhealthy soil (2).
In-ground disposal also greatly reduces the risk of disease from fecal contamination. According to the CDC, pet waste contains bacteria and parasites that can infect humans and other pets (3). Proper disposal via an underground system helps prevent the spread of giardia, salmonella, hookworms, and other pathogens to people and animals in the yard. This is especially important for families with small children who may come into contact with surface waste while playing.
Finally, in-ground systems provide an environmentally friendly disposal method compared to simply bagging up dog poop and sending it to the landfill. Pet waste contains nutrients like nitrogen and phosphorous that can contaminate groundwater if allowed to seep into storm drains and waterways (4). Safely decomposing it underground minimizes this potential for pollution.

Types of In-Ground Dog Waste Disposal Systems
There are three main types of in-ground dog waste disposal systems:
Basic Gravity-Fed Systems
Gravity-fed systems are the most basic and affordable option. They consist of an underground septic-style tank that holds the waste. The tank has an opening at ground level where you deposit the waste. Once inside, the waste breaks down naturally over time.
Systems with Grinders
More advanced systems include a grinder mechanism that breaks down the waste before it enters the tank. The grinder allows for faster decomposition and less buildup inside the tank.
Systems with Heated Processing
High-end systems use a heating element to help break down and evaporate liquid waste inside the tank. This speeds up processing significantly but uses more electricity.
Comparison of Types
Gravity-fed systems are the most affordable option but require more frequent maintenance. Systems with grinders provide faster processing for a higher upfront cost. Heated systems are the most expensive but require the least maintenance over time.
Installation
Installing an in-ground dog waste disposal system involves digging a hole, positioning the tank, connecting plumbing and ventilation, and routing the drainage pipe. Here are the key steps:
First, dig a hole 2-3 feet deep and slightly larger in diameter than the tank. The tank should be buried below the frost line to prevent freezing in winter. Choose a spot with good drainage that is downhill from where the dog poop will enter the system (Source: https://www.thewildest.com/dog-lifestyle/build-your-own-pet-waste-digester).
Next, place the tank in the hole and backfill with 6-12 inches of gravel for drainage. Make sure the tank is level. Connect PVC pipes for inlet, outlet, and ventilation following instructions. Ventilation helps circulate air and keep the digester working properly.
Finally, route the outlet drainage pipe to a landscaped area, garden, or downhill away from wells or water sources. This safely disposes of the liquid waste after digestion. Install an elbow or screen on the outlet pipe to keep out pests (Source: https://www.youtube.com/watch?v=if_nHfA93Mk).
With proper installation, an in-ground dog waste system can handle waste from multiple dogs for years. Make sure to follow all local codes and regulations.
Maintenance
In-ground dog waste disposal systems require some periodic maintenance to keep them functioning properly. Here are some key maintenance tasks:
Periodic cleaning and sanitizing:
- Remove solid waste monthly or as needed to prevent buildup.
- Wash out the tank every 6 months using a hose and mild detergent. Allow tank to dry completely before replacing drain field materials.
- Sanitize tank yearly using a chlorine bleach solution to kill bacteria.
Checking and replacing parts:
- Inspect and clean inlet/outlet pipes yearly.
- Check aeration system is working properly.
- Replace drain field gravel/materials every 2-3 years.
- Replace any worn or damaged parts as needed.
Managing drainage field:
- Evenly distribute effluent over entire drain field area.
- Ensure proper grading for effluent to flow away from tank.
- Do not allow vehicles to drive or park over the drain field.
- Plant only grass over the drainage area.
Regular maintenance helps ensure the system works efficiently to break down waste and prevent clogging or leaks. Checking the tank, pipes, and drainage field periodically is key to avoiding more serious problems down the line.
Cost
The cost of an in-ground dog waste disposal system can vary significantly depending on the type of system you choose and whether you hire a professional to install it or do it yourself. Here are some of the main costs to consider:
Purchase Price
Basic disposal units that consist of an in-ground bin start around $50-100. More advanced systems with automatic cleaning features can cost $500-1000 just for the unit itself. The type of activation method (step, electronic, etc) will also impact price.
Installation Cost
Installing an in-ground dog waste unit requires digging a hole 12-24 inches deep and wide enough to fit the unit. Doing this yourself can save on labor fees, but be prepared for a solid day’s work of digging and getting dirty. Hiring a landscaping professional to install will likely cost $200-500 depending on system complexity and local rates.
Maintenance Costs
Basic units will need the bin emptied when full and occasional cleaning with a hose. Advanced systems with automatic cleaning features reduce but don’t eliminate maintenance. Average maintenance time is 5-10 minutes per week and supplies are minimal. The main ongoing cost is replacing the biofilter or cleaning solution every 1-2 months, which runs around $20-50.
Safety Tips
In-ground dog waste disposal systems require proper precautions to ensure safe operation. Here are some key safety tips:
Proper ventilation – Methane and other gases are produced as waste breaks down in the tank. Ensure the system has adequate ventilation per the manufacturer’s guidelines to avoid buildup of harmful gases. Vent pipes should extend above ground level and away from windows or vents.https://extension.psu.edu/roadside-guide-to-clean-water-proper-pet-waste-disposal
Keep children away – Access lids and panels should be securely fastened to prevent children from accessing the waste tank. Educate children on the hazards and supervise them around the system.
Avoid electrical hazards – Any pumps or aerators should be properly grounded and installed per local electrical codes. Use GFCI outlets and inspect cords periodically for damage. Keep electrical components away from liquid waste to prevent shocks.
Best Practices
When installing and using an in-ground dog waste disposal system, following best practices can help ensure proper functioning and environmental safety.
Ideal installation locations for these systems are in shaded, well-draining areas of the yard that won’t flood. Proper drainage prevents waste and liquids from pooling on the surface. Shade helps regulate internal temperatures for more effective composting.
Using biodegradable dog waste bags is highly recommended, as they break down within the system. Standard plastic bags can clog pumps and mechanisms.
It’s important to carefully follow the manufacturer’s instructions for installation, maintenance, and proper use. Taking shortcuts or failing to perform regular maintenance can cause problems. Periodic additions of compost starter, enzymes, or microbial boosters helps optimize decomposition.
Comparisons
In-ground dog waste disposal systems have some key advantages over other disposal methods like trash cans or traditional composting bins. Unlike taking the waste to the trash, in-ground systems keep odors away from the home and break down waste more naturally. Compared to open compost piles, they are more sanitary and contained. In-ground systems also take up less space than compost bins.
When comparing brand options for in-ground disposal systems, the Doggie Dooley is a top choice. It has a durable polyethylene construction and uses a bio-enzymatic solution to accelerate breakdown of waste. The Doggie Doo Drain is another quality option made out of recycled plastic and using natural enzymes. It comes pre-assembled for easier installation. Other brands like the Pet Waste Coach and the Doggy Dooley are also available, but may not have as large of a capacity.
Ultimately, in-ground dog waste disposal systems are more effective and hassle-free than other disposal methods. The Doggie Dooley stands out as a top brand with an efficient design and reputable performance.
