Why buy an in-ground disposal system?

The importance of a waste-free yard and lawn is not only an environmental issue but also a family health issue. Animal waste that is not cleaned up can become a breeding ground for bacteria and diseases that can be transmitted to humans, and also put the health of your pets in jeopardy.

There are many ways to clean up animal waste from your yard and lawn area, but lately, the most popular method people choose is the In-Ground Waste Digester System. There are various models for you to choose from and they all work on the same principles as a septic system.

  • You must first dig a hole in a convenient and out-of-the-way area in your yard in the spot you wish to place the digester. The hole must be no more than 48 inches deep in order to facilitate drainage. Install the digester and cover it in the ground. The cover should only be slightly above the ground.
  • After your pet has deposited his waste, pick it up, and place it in the digester.
  • Add special enzyme stool digester mixture and water and place the lid back on the digester. Some digesters come with a pedal apparatus.
  • Let the digester do its job – the digester liquefies the stool and drains it into the surrounding soil.
  • Forget about it until the next time and enjoy your clean lawn!
  • The liquid stool product is not harmful or a danger to the environment.

The In-Ground Dog Waste Disposal System that you can buy in 2019 is practically level with the ground so it is not obvious to the eye of passersby. You would be surprised how easy it is to clean up your pet’s waste by using one of these systems mentioned below. Also keep in mind that if you feed your dog’s high protein or concentrated premium foods, you will have to purchase a special digester because you will need a specific bacteria/enzyme mixture to liquefy the stools.

What to look for when buying a waste disposal system

There are some things to keep in mind while looking for a disposal system.

Technique – There are two types of in-ground disposal systems: Sewer line attachment and septic tank. Both work well, but different. So pick which one fits you best.

A sewer line attachment is, as the name suggests, attached to a sewer. It doesn’t matter how many dogs you have. You don’t have to buy extras like Waste Terminator powder or tablets. It is relatively cheap.

A septic tank works like a miniature septic tank. In most cases, you’ll need water and a powder or tablet. These will work together with nature to digest the dog poop. A septic tank does work for a limited amount of dogs. The smaller tanks work for 1 large dog or 2 small dogs and the bigger tanks work for 2 large dogs or 4 small dogs.

Amount of dogs – As we’ve mentioned above, not all options work for a large number of dogs. If you have 1 large dog or 2 small dogs, there is no problem. But if you have multiple large dogs, you have limited options. Your options are the large pyramid septic tank or the sewer line attachment.  You can also choose to buy multiple septic tanks.

Material – Most options are made out of durable plastic. The Doggy Dooley 3000 is made out of strong, galvanized steel. So this might be a stronger and more durable option. This option is also a bit more expensive but probably will last you longer. The customer reviews are very good, so a lot of happy dog owners for the Doggy Dooley 3000.

Price/quality ratio – While picking a dog waste disposal system, check for the price/quality ratio. In this article, we’ve already done the work for you. If you’re not sure about the quality, search for customer reviews. This can either be on Amazon, or on google.

How to build your own waste digester?

1. Take an old plastic garbage can and drill a dozen or so holes in the sides.
2. Cut out the bottom.
3. Dig a hole deep enough for the garbage can.
4. Toss some rocks or gravel in the hole for drainage and position the garbage can so it’s a little above ground level.
5. Place the lid on top.
6. Start scooping.

Best way to Dissolve Dog Poop

Wintertime is not the best time to step outside to pick up after your dog especially when it is snowing. Dog poop freeze to the ground as soon as it is left behind. Springtime is the best time of the year to get handy picking up dog poop. But the best option available to you is to dissolve it.

  1. Wait until the snow melts and then pick up the dog stools while it is still hard
  2. Drop your dog’s stools in a container with a lid or use one of these above mentioned in-ground dog poop disposal systems.
  3. Drop some enzyme power or tablets into the bucket. These can be purchased from online pet supply stores. Add some water and leave it to dissolve.
  4. Next, you want to use a high-speed sprayer to get rid of the remaining dog poop.
  5. Powdered or pelletized lime can be purchased as a lawn fertilizer if necessary. This will instantly help to dissolve leftover poop and eliminate dog poop odor.

Can you turn dog poop into fertilizer?

The general answer to that question depends on how concern you are about your pet’s and your family’s health. So, in short, yes but we suggest that you take proper precautions because both cat and dog poop can be dangerous to human health.

Cat feces – pose a more significant danger to human health. The reason for this statement is that cat feces transmit toxoplasmosis which is a disease that is dangerous to pregnant women. It can do serious harm to the unborn child’s central nervous system.

These effects can be detrimental and could lead to fetal blindness, brain damage and many other problems. Because the symptoms are similar to a flu virus the disease is often diagnosed as a familiar ailment. It is estimated that almost 50% of Americans have been affected by this parasite at one time or another. Cat manure should always be handled with extreme care and it is not advised that pregnant women should stay away from cat manure. Furthermore never use cat poop in your food garden, rather bury it with non-food plants.

Dog poop – roundworms are the primary hazard in dog stools. Their stools can be used in your garden but first needs to be composted. To produce the best soil rich compost the limiting factor is the temperature of the compost pile. Compost piles can be done by hand but speed this up you can always choose one of these Outdoor Composting Bins. They are great for producing yard waste and it’s not labor-intensive.
