How to Design a Septic System for a Dog Shelter

Doggie septic systems are a great convenience for a home owner, especially when paired with a shelter like a dog house. Canine waste disposal systems built on a scale large enough to accommodate a kennel or breeding facility are subject to zoning regulations, so consult with your zoning board when planning a system for more than a couple of dogs.

  1. Planning, Excavation, Creation and Installation

    • 1

      Plan your system. There are several aspects to consider; all are important and could cause the system to fail at some point down the line. Just like a system for people, it should be located away and down hill from any wells, human septic systems, houses and other structures.Call before you dig to make sure you do not disturb any existing power line or other utilities. Check the soil type. Clay soils require a larger drainage system than sandy soils.

      Turn your trash can over and mark your spot to dig by making a circle with the shovel blade around it. Dig deep and wide enough to accommodate your system and at least 6 inches of drainage around and beneath it. In heavy soil you may want to create a larger drainage field to prevent backup.

      Cut off the bottom of the trash can and drill four or five rows of 1/4-inch to 1/2-inch holes, 2 inches apart, around the bottom of the can. The rows should come 8 inches to 10 inches up the side of the can. Use more rows in heavier soils to allow for additional drainage

      Fill the hole with a base of stones larger than 1 inch in diameter to about 6 inches deep. Your system should rest on this base with an inch or two exposed on the top to give enough space to open and close the lid. Put the can in the hole add gravel to about 1 inch below the top row of holes. Fill around the outside up past the top row of holes with stones, alternating with gravel to fill in the gaps between the stones and to create a buffer so dirt does not filter back and clog your system.

      Use water to settle the stones and gravel and fill in any dips or uneven surfaces to level the system. Pack the soil as tightly as possible as you fill in around the system. Once this step is completed you can lift the lid and start using your new doggie septic system.
