Sewer belly — low spot in the line, standing water at rest.
A sag in the lateral sewer line where slope is lost. Solid waste settles, water pools, the section becomes a chronic clog. We document depth and length on video, tag severity, and frame the negotiation context.
Old clay, mature oaks, settling till.
Eden Prairie's 1970s and 1980s housing — original Round Lake area, Mitchell Lake margin, Eden Prairie Center area — runs clay tile or early cast iron bedded directly in native glacial-till soils. Mature oak root pressure, frost-line cycling, and decades of unequal soil settlement combine to drop low spots into the run. The pattern is so common in this era cohort that we recommend a sewer scope as non-optional on any home over 25 years old.
Six belly variations on the camera.
Not every belly is the same. Depth, length, and where it sits along the run change the severity, the repair, and the negotiation.
Shallow belly
Light pooling, less than an inch standing. Manageable with periodic jetting. Track for change at next scope.
Moderate belly
Two to three inches at rest. Spot excavation indicated. Documented depth and length used for negotiation.
Deep belly
Half-pipe submerged. Chronic clog source. Excavation and re-bed of the failed section is the standard repair.
Multi-belly run
Two or more low spots in series. Indicates run-wide settlement. Often points to full lateral replacement.
Belly + root colony
Standing water invites root intrusion at the low point. Compound finding — clearing roots alone won't fix slope.
Belly at offset joint
Low spot caused by an offset joint. Excavation needed regardless — repair the joint and re-bed in one pass.
Where bellies cluster.
Era and pipe material drive the rate. Use this as a pre-offer screen — and book the scope regardless on any home over 25 years.
| Area | Build era | Lateral material | Risk |
|---|---|---|---|
| Round Lake area | 1968–1985 | Clay tile · cast iron | High |
| Mitchell Lake (original) | 1972–1986 | Clay tile | High |
| Eden Prairie Center area | 1975–1990 | Cast iron · clay tap | Medium |
| Cedar Forest | 1985–2005 | Cast iron · early PVC | Medium |
| Hennepin Village | 1998–2008 | PVC SDR-35 | Low |
| Bearpath | 1992–2010 | PVC · ductile at main | Low |
Three steps. Recorded, tagged, framed.
Push the camera to the main
Self-leveling sewer scope camera pushed from the cleanout. Full HD video the entire run. On-screen distance counter and material annotation.
Tag depth and length
At each belly, we record distance from cleanout, estimate water depth from the camera's submersion line, and note approximate length. Stills of the deepest point.
Severity and repair frame
Each belly tagged Critical / Major / Monitor with a plain-language repair frame and a repair-cost reference for negotiation context. Same-evening report with the video and stills.
