Septic Tank Abandonment and Decommissioning
When a property connects to sewer or replaces a system, the old tank has to be properly abandoned. An empty buried tank is a collapse hazard and most Colorado counties require documented decommissioning.

Septic tank abandonment Septic tank abandonment is the permanent decommissioning of a tank that is no longer in use, by pumping it dry and then crushing, filling, or removing it under county rules. It is documented for the property record.
An empty, buried tank is a collapse hazard, and an undocumented one can stall a sale or a building permit.

The situation
Why an old tank cannot just be left
An abandoned septic tank that still holds waste is a contamination risk, and once it is empty it becomes a void under your yard. Old concrete and steel tanks lose strength over time and collapse under vehicles, equipment, or a person standing in the wrong spot.
Counties handle this with a decommissioning requirement. The tank is pumped and cleaned, then either crushed and backfilled in place or removed entirely, and the work is recorded. Buyers, lenders, and title companies increasingly ask for that record at closing.
How the job runs
How decommissioning works
Confirm the county requirement
Crush in place and removal are both accepted in different jurisdictions. We check before scheduling.
Pump and clean the tank
Everything is removed and hauled to a permitted disposal site.
Disconnect and seal lines
Inlet and outlet lines are cut and capped so nothing drains into the abandoned structure.
Collapse or remove, then restore
The tank is crushed and backfilled with clean fill or lifted out, then the site is graded.
