DUNBAR
Hello MasterofNone and thank you for joining MasterPlumbers.com!
In regards to your situation,
What matters the most in your situation is the soil being able to absorb the effluent that travels from your septic tank to the leach fields.
The replacement of the structure is required, but I would have a perc test done on your soil. This gauges the absorption rate that the ground will take over a short period of time.
If the perc test reveals the ground is no longer effective in doing this (a common situation with aging systems) then you will have to bring in topsoil to the location where the ground is completely used up, or dedicate a new area of ground on your property to achieve the ability to slowly dissipate the effluent into the ground.
There are no ‘cures’ to this situation as the ground will eventually become a product of what it has been collecting for many years.
The result of which is if you go through these efforts without checking into this matter, you’ll find out that the effluent will travel and collect above ground as it has no place to go.
