cleaning indoor sewage spills

In the event of an indoor sewage spill, thorough cleaning is necessary so that people, especially small children, are not exposed to potentially harmful bacteria and viruses. The amount of cleanup work depends on the extent of the problem, but general Guidelines for Cleaning Indoor Sewage Spills are available to help.

Septic Tank Abandonment

The Washington Administrative Code (WAC) contains regulatory requirements for septic tank abandonment. The Snohomish County Health Department does not have additional regulations.
