A Replacement Septic Tank Installation Starts By Properly Decommissioning The Old Tank

If your septic tank is damaged beyond repair, you'll need to get a new one so you don't have to worry about sewage leaking in your yard. Sometimes, tanks can be repaired by sealing cracks in concrete, but if the contractor doesn't think that's possible, you'll need to go through the process of having a new septic tank installed. This is an involved project that entails digging up the old tank. Here are some steps to installing a septic tank.

Expose The Old Tank And Demolish It

The first step in septic tank installation is to get the old tank out of the way. This may be done by demolishing it and leaving it in place. The contractor can dig earth away so the tank is exposed and then use heavy equipment to break the tank apart. They'll also need to punch or drill holes in the bottom so the tank won't hold water when it rains. Once the tank has been broken up, it will be covered with dirt and compacted so it is decommissioned properly according to city codes and health department regulations.

Choose Where To Put The New Tank

The contractor decides where to put the new tank based on what local codes allow and the space that's available. If possible, they'll place the new tank next to the old tank so the new tank can fit the existing sewer lines easily. When the location is chosen, the contractor has to dig a hole for the tank. Part of the dirt is then used to bury the old tank if needed, and the rest of the dirt will be backfilled next to the new tank.

Place The New Tank In The New Hole

A septic tank is precast, so it arrives at your property already made and ready to hook up. The tank is heavy since it's made of concrete, but a crane can lift it easily and maneuver it into the hole. Once the tank is in place, it's attached to the sewer main drain at one end and the exit drain to the distribution box on the other end. Before the tank can be buried, it needs to be inspected by the city to make sure the work is done according to code. Once the soil is backfilled, the tank will be out of sight except for the risers that are on top of the lids. The risers are visible so the contractor can find the tank and lids easily when it's time to pump out the tank.
