How to Remove a Septic Tank Lid How to Remove a Septic Tank Lid
A septic tank lid is the uppermost portion of the sewage tank. This lid needs to be removed every few years in order to empty the tank. Depending on the size of the tank a homeowner will need to have the septic tank emptied every three to five years. It is important not to let the tank get too full, start to back up into the house, or overflow out of the lid. This causes severe damage to the tank. Removing the lid is an easy task that can be done before the pumping service gets there.
Step 1: Locate Septic Tank
If you have just purchased a home, or are having the septic tank pumped out for the first time you will need to locate the tank itself. Depending on the size of your lot, and the type of ground you are on (sand, ledge, clay) the tank can be just about anywhere. It should be stated in your property deed where the tank is located, but it may be approximate. There are three surefire ways to find the tank, but they do require time.
Use a metal detector to find the septic tank. Most tanks today are made out of concrete material, but they have metal rebar in them. With the use of a metal detector you can go to the approximate location and start searching. One you find the tank, it is a matter of digging up to find the lid.
Use a metal pole to poke into the earth to locate the tank. This can be time consuming if the property deed is not right. Simply poke the metal pole into the earth about 12 to 14 inches. Once you strike something solid continue in the area to determine that it is the tank.
You can also follow the drain pipe that comes from your home. However, this method entails digging up your yard to follow the pipe to the tank.
Step 2: Dig Up Septic Tank Lid
After you have found the septic tank, you can begin the process of digging up the lid. Use a shovel to excavate the ground around the tank until you find the lid. It will be flat against the tank with a small seam around it. Dig the ground to create at least 16 inches of clearance on all sides of the lid. It is also recommended that you slope the land as you dig down to the lid so that the gravel will not fall back in.
Step 3: Pry Off Septic Tank Lid
Depending on the size of the septic tank, the lid can be quite heavy. It is a solid piece of concrete that is flat on all sides. It may have a handle to pull on. The majority of lids will require a prybar to lift them out of their seating. Set the prybar in the seam and press down. As the lid lifts out of the hole, have someone move it to the side. Set the lid on the surface of the ground out of the way of the pumping vehicle.
