Ejector Pit Odor Treatment in New Haven
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 university dining halls, hospital campuses, and a dense downtown restaurant scene.
Why New Haven properties need this
New Haven runs on Yale's dining and hospital density plus one of the best independent restaurant scenes in New England. Grease trap and drain programs are what keep the health department out of the room.

Ejector Pit Treatment in New Haven — 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 New Haven on a regular schedule?
Yes — weekly routes. We route New Haven weekly for existing accounts and offer same-week site walks for new properties across Downtown, East Rock, Wooster Square and the rest of New Haven.
What types of New Haven properties do you work with for ejector pit treatment?
The ejector pit treatment program in New Haven is running in university dining, hospitals, restaurants, and across the property types most common to the market. If your property type isn't listed, most programs adapt without any changes to scope.
