Septic tanks come with a myriad of concerns, but no problem might be less anticipated and more frustrating than roots in your septic tank. If you have a large tree or multiple large trees around your septic tank, it is only a matter of time before the roots find it. A septic tank provides water and nutrients, which roots love. If you already have roots in your septic system, it is time to call and have them removed. If you recently had roots removed, or want to prevent roots from becoming a problem again, there are a few ways to keep them away from your septic tank.
If you want to prevent roots from growing in your septic tank, or anywhere in your plumbing, there are products available to battle the problem from the inside out. Products like Roto-Rooter Root Destroyer are administered easily by pouring them into a toilet and flushing, or pouring some down a drain, but each product has specific instructions. Familiarize yourself with the instructions on the product before using it to make sure you use the right amount in the right way.
Another way to control root growth is to take the battle to the roots themselves. There are chemicals available that will deter root growth. To set up a sort of force field, dig a line of small holes into the ground between the guilty tree and the septic tank, then administer the root killing chemicals into the holes, and fill them back up. It’s just like a fence that keeps an overly enthusiastic dog from getting into trouble.
Root barriers are more similar to an actual fence. Root barriers are solid sheets or panels of hard plastic or other materials that are buried into the ground. When a root comes into contact it physically cannot penetrate the material so it can’t get near the septic tank. It is important to note that when you stop a tree’s roots from freely growing, you are jeopardizing the health of the tree. A tree needs an adequate root system not only for nutrition, but also to keep it anchored and balanced. Sometimes removing the tree is a better option than attacking its roots, or better yet, just plant smaller, more appropriate trees in your yard.
