Sewer Line Replacement in Grand Rapids, MI

When Excavation May Be Required

Open-cut excavation involves digging a trench along the pipe run, removing the damaged section, and installing new pipe at the correct grade. It is an option when the line cannot be rehabilitated in place or when pipe bursting is not feasible given the site conditions.

Pipe bursting is a different full-replacement method that displaces the existing pipe outward while pulling a new pipe through the alignment. It has its own candidacy requirements related to access, soil, alignment, utilities, and connections. Neither method can be promised before the line and site have been evaluated.

Open-cut may be considered when conditions such as hard collapse, severe pipe deformation, significant grade problems, or failed service connections make in-place rehabilitation or bursting impractical. The provider should document the property-specific evidence for the recommended approach before work begins.

Additional conditions that may be relevant include:

• Severe pipe bellies: Sections of pipe that have settled, creating a low spot that holds standing water and waste. Lining cannot correct grade issues.
• Collapse: A pipe that has crushed inward, blocking flow and preventing a camera or liner from passing through.
• Heavily deformed pipe: Bituminous fiber or other pipe material that has lost structural integrity and may not support a liner.
• Severe channeling or bottom-rot: Old cast iron pipe where the bottom has corroded to the point where nothing remains to hold a new liner.
• Severe offset joints: Clay or concrete pipe sections that have shifted so drastically that a liner cannot navigate the transition.

No single condition automatically requires one method over another. The appropriate path depends on the full picture — access, pipe condition, nearby utilities, local requirements, and the provider's documented scope.

The Replacement Process

Because replacement requires heavy equipment and trenching, it involves rigorous safety and municipal compliance steps. The provider must explain which approvals apply, who will obtain them, and how those responsibilities appear in the written scope before any work begins.

Key steps typically include: diagnostic camera inspection, utility locating via MISS DIG 811 (at least three business days before digging), securing required permits, excavation and pipe installation, municipal inspection, backfill, and surface restoration.

Provider capabilities, permit handling, and restoration scopes vary. Confirm all responsibilities and inclusions in the written scope before authorizing work.
