septic tanks are in

The two septic tanks were installed today. The drain pipe from the house empties into the first tank (the one with the two green covers) which has two chambers separated by a baffle. The first chamber does the "heavy lifting" - separating most of the stuff that either floats or sinks from just dirty water. The second chamber (of the first tank) does more of the same and then pipes the dirty water to the other tank which is the pump chamber. From there, it is pumped to the biofilter (previous posting) which purifies it.

These tanks will be completely buried. There will be "risers" installed where there are now only those green covers. The risers will provide access to the 3 chambers in the 2 tanks from above ground.

Connecting these tanks to the biofilter is tomorrow's job.
