Start with location
An inspection should identify whether the problem is inside the building drain, along the private lateral, at the connection, or in the public system. Do not approve private excavation until the location is reasonably established.
Confirm the private, public, and main boundary before assigning responsibility for the blockage.
Joliet public-system path
Joliet directs residents with a suspected sewer break or sewer issue to Public Utilities for an inspection.
That city step does not diagnose every private line or guarantee assistance. The defect location and proposed private scope still need to be documented.
What to document
Keep the camera findings, measured location, cleaning notes, photos, city or utility case information, and the proposed private scope together before work begins.
