Septic Tank vs Drain Field
Understand the difference between a septic tank and a drain field.
What the septic tank does
The tank receives wastewater, lets solids settle, and holds sludge and scum so liquid effluent can move onward.
What the drain field does
The drain field distributes effluent into the soil for treatment and dispersal. Soil condition and saturation matter a lot.
When the yard is wet, odors are outside, or backups return after service, the next planning step may be drain field repair in Casper rather than routine tank pumping alone.
Why the difference matters
A backup, odor, or wet yard can involve the tank, drain field, line, usage, or several issues at once.
