DVS Uncategorized

You may know what your septic tank is and what it does, but do you know where to find it? If you’re not a professional in the field, it can be tough figuring out where your septic system resides.

At Delaware Valley Septic, Sewer, and Storm, we provide septic repair and replacement to those in Chester County, PA, as well as the surrounding area. One of the biggest questions that we’re asked by people is, “How do I find my septic tank?” If your tank has been causing you problems, then it may be time to get it checked. Here’s how to find your property’s septic tank and get to the root of the problem as soon as possible:

  1. Ask your county – It turns out that most counties hold onto records of the septic tanks that are built on each property if they were put in after the county started its map-collecting process. It’s worth a shot! You can start by calling or visiting your local county office to request a map of the septic tanks in your area.
  2. Inspect your property for signs of your septic system – If your county doesn’t have a map or if your tank isn’t shown on it, you can inspect your property to look for signs of your septic system. Investigate to look for any visual clues that may indicate there’s a septic tank nearby. These include pipe cleanouts, grass or ground that appears different, or the actual lid itself.
  3. Pipes will lead you to your septic tank – If that doesn’t work, remember that all septic tanks have some kind of connection to your house, usually in the form of a pipe. If you have a basement, find a space where the sewer line leaves your house and follow it outside. Most of the time, you’ll be able to find the septic tank about 20 feet outside of your home.
