Ejector Pit Odor Treatment in Baltimore
Below-grade ejector pits are the #1 hidden source of building-wide sewer odor. We treat the pit, the vent, and the discharge — not just the smell in the lobby. Built for harbor-front hospitality, hospital campuses, and legacy row-house residential.
Why Baltimore properties need this
Baltimore's harbor-front hospitality and Johns Hopkins-anchored hospital density set the pace. Legacy row-house residential adds the historic-stack work most weeks.

Ejector Pit Treatment in Baltimore — 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.
Do you service Baltimore on a regular schedule?
Yes — weekly routes. We route Baltimore weekly for existing accounts and offer same-week site walks for new properties across Inner Harbor, Fells Point, Federal Hill and the rest of Baltimore.
