Chemical Lawn Treatments & Your Septic System

Are Chemical Lawn Treatments Bad for Your Septic System?

We will not straight out advise against chemical lawn treatments totally. The septic tank and drain field should be securely sealed and installed deep in the yard anyway. Plus, fertilizers, pesticides, and weed killers are usually designed to dissolve near the surface of the yard. When applied correctly, these products will not necessarily harm your septic system. However, they should be applied correctly. Be sure to follow the packaging directions carefully. Also, remember to have your septic system routinely inspected to ensure that it is not exposed to the surrounding.

The Threat Chemical Lawn Treatments Do Pose

Your septic system uses a combination of chemical and biological methods to break down waste into sludge. The biological method involves vital “good” bacteria that decomposes solid waste into space-saving sludge. Chemicals found in fertilizers, pesticides, and weed killers can threaten that vital bacteria. So, it is important that the bacteria are not exposed to the chemical lawn treatments. Make sure that your septic system is sealed securely without cracks and loose points.
How you dispose of the unused chemical lawn treatments is also crucial. Homeowners often make the mistake of flushing the leftovers down the toilet or the sink. You should never pour chemicals down your drains. This can wipe out the bacteria and overwhelm your septic system, forcing you to get premature septic cleaning or even a replacement.

Extra Safety Steps You Can Take

We appreciate a lush, green lawn as much as the next guy, but we always advise the safest route toward that end. There are ways to have a gorgeous yard without relying heavily on chemical treatments. First, opt for plants, shrubs, and turfgrass that is native to your area. They will be more likely to suffice with the available water and nutrients in the environment. Secondly, consider natural fertilizers like organic compost, attract natural predators instead of pesticides, and use a homemade solution of vinegar, salt, and dish soap instead of weed killers.
