Septic waste disposal repair small area

[jj666]

I have a very small yard/ space on a property to provide a repair solution for a failing septic system. It is an old gravity system but current code will not allow gravity because there is not enough soil. Soil is 58 inches sandy loam. I need 3 feet of effective soil below bottom of trench. I do not get any sidewall credit. I was planning on using pressure dose to shallow trenches with 9-12 inch infiltrators. The tank needs to be replaced and it was suggested I use a pump vault. Can anyone here recommend a good tank/field combo? Thank you!

I would suggest you post this in the "Waste Disposal & Treatment" forum.

Local rules will determine what your options are.
Here everyone who doesn't have a lot of land is being forced to engineered mound systems.

Mound system may work. The footprint may be too large to fit in a "small yard"

U of MINN is also a great source for septic system info.
With so many lake houses (small lots and high water table) they have done a lot of good research.
