Read the pattern
Gather the side sewer card or map, legal address, connection point, cleanouts, building exits, prior footage, repair history, slope features, shared-line evidence, and surface constraints.

Move from evidence to a bounded authorization
Hold the safety line
Never enter a sewer, unsupported excavation, or traffic area. Locate utilities and resolve access, shoring, contaminated soil, and public-right-of-way controls before intrusive work.
Place the Seattle boundary
SPU maintains the sewer main while the owner is responsible for the side sewer. Records can guide planning but need field confirmation before excavation or a final ownership conclusion.
Write the visit
Define endpoints, access, cleaning or camera work, defect location, method, permit, inspection, bypass if needed, excavation controls, backfill, surfaces, and updated route documentation.
Keep the closing evidence
Keep measured locations, video, permit and inspection records, pre-cover images, installed materials, tests, restored cleanouts, and the final surface status for later property decisions.
