Camera inspection

Overhead sewer conversion with an ejector pumpCross-section: basement fixtures drain to a sealed ejector pit. The pump lifts wastewater up to a new overhead sewer line near the basement ceiling, which exits above the old floor-level connection. Upper-floor fixtures drain by gravity to the overhead line. BASEMENT upper-floor drains (gravity) sealed ejector pit WC old low connection (plugged) to street sewer 1234
Diagram An overhead sewer keeps the building's sewer connection above the basement floor so a backed-up street sewer cannot flow in through floor-level openings.
  1. Ejector pump with check valve lifts basement wastewater up; it needs power, so outages matter.
  2. Overhead sewer line runs near the basement ceiling.
  3. Building sewer exits the wall at a higher elevation.
  4. Former floor-level openings are sealed under the design.
