Ejector Pit Odor Treatment in Philadelphia Main Line
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 country clubs, private schools, and legacy residential along the R5 corridor.
Why Philadelphia Main Line properties need this
The Main Line's country clubs and independent schools have decades-old kitchens and drain infrastructure that need programs, not one-off jetting. Weekly cadence keeps everything ahead of the complaint call.

Ejector Pit Treatment in Philadelphia Main Line — 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 Philadelphia Main Line on a regular schedule?
