Infiltration Chambers In Trench
Because my soil didn't drain well I needed 20' of infiltration chambers (in a 30' trench) 8 feet deep.
Infiltration Chambers and Caliche
This shows why I needed 20' of infiltration chambers (in a 30' trench) 8 feet deep. I had 18" of rocky, poor draining soil above 4 feet of caliche - the white rocky layer in the picture. A backhoe can dig through it but it's tough. The drainage rate of caliche seems glacial. Here is how Wikipedia describes Caliche: "Caliche (/kəˈliːtʃiː/) is a sedimentary rock, a hardened natural cement of calcium carbonate that binds other materials—such as gravel, sand, clay, and silt. It occurs worldwide, in aridisol and mollisol soil orders—generally in arid or semiarid regions. . . " Beneath the caliche was more rocky, poor draining soil In this picture I had just covered the lower flanges of the infiltration chambers as well as the drain pipe entering them under the dirt pile at the top of the picture.
My van with a load of 10' pipe, nestled between the seats at the front end.
A good reason to fill in trenches asap in the desert.
