Ejector Pit Treatment in Washington, DC — FAQ
Why is the ejector pit the hidden culprit?
Because most buildings don't know it's there. Ejector pits sit below the sewer line, collect everything from the lower-level fixtures, and generate H₂S continuously — but they usually aren't on any maintenance calendar until we find them during the audit.
Why does the odor come back after a vac-truck cleanout?
A one-time cleanout removes accumulated solids but doesn't stop the bacterial process that creates the odor. Within days, biofilm re-establishes and H₂S returns. A monthly bio-dosing program keeps the pit from re-generating odor between cleanouts.
Do we need to shut down the pit for service?
No. Dosing and foaming happen with the pit fully operational. There's no downtime.
