Sewer work depends on grade and timing
Gravity sewer lines need the correct route and fall. The trench also has to fit the connection, bedding, pipe work, inspection and safe backfill sequence. That makes sewer excavation a coordination job from the first layout mark.
C&H handles excavation and site work while the appropriate licensed trade handles regulated plumbing connections and pipe installation as required. We keep access, spoil and restoration aligned with the approved plan.
REVIEW THE SEWER ROUTE
Sewer-line excavation and site support
The written scope should show exactly where excavation ends and licensed plumbing work begins.
Trench excavation
Open the approved route and connection areas to the specified depth, slope and working clearance.
Bedding and access
Prepare specified pipe bedding and keep connection or inspection points workable.
Backfill and restoration
Coordinate approval, place approved material, compact and restore the disturbed surface.
City sewer verification, connection requirements and plumbing permits may apply. Those approvals should be confirmed before excavation is scheduled.
Connections and public systems add checkpoints
The City of Lake Oswego can verify whether a property is connected to public sewer and directs new connection questions to Engineering. Work tied to public infrastructure, streets or easements may require additional permits and inspections.
We plan the dirt work around those checkpoints. An open trench waiting on missing information is not productive, and it is certainly not improving anyone’s week.

Lake Oswego sewer-line FAQs
Can you confirm whether my property is on sewer?
The City of Lake Oswego can check its records and may use dye or smoke testing when records are unclear. Start there before planning a new connection.
Does C&H perform the plumbing connection?
C&H provides excavation and related site work. Regulated plumbing and sewer connections are handled by the properly licensed trade. The proposal will state responsibilities clearly.
Can you replace a sewer trench through landscaping or pavement?
Often, yes, but access, surface removal, permits and restoration need to be part of the scope before work begins.
Need an excavation plan for sewer work?
Share the plumber’s scope, connection information and any City requirements. We’ll coordinate the trench, access and restoration around the approved work.
