Septic Backup Investigation and Assessment in Arcadia, Michigan

When a septic system starts backing up, the problem is often much bigger than what is visible at the surface. What may seem like a simple blockage can actually point to drainage failure, outdated infrastructure, improper pipe pitch, or a system that has reached the end of its life cycle.

That was the case during a recent septic assessment completed by GWJ Excavation and Site Prep in Arcadia.

Investigating the Cause of the Septic Backup

Our team was called out to evaluate ongoing septic backup issues at a residential property. Rather than relying on assumptions or temporary fixes, we approached the project with a full investigative process to identify the actual source of failure.

The existing system consisted of:

An older concrete septic tank located inside the garage
A secondary dry well/catch basin disposal setup outside the home
Aging outlet piping with questionable drainage flow

To properly assess the system, our crew:

Opened and inspected the existing concrete tank
Performed a camera and visual assessment
Excavated multiple locations to trace the septic layout
Exposed the outlet pipe
Investigated for an existing septic field
Located and uncovered the secondary dry well/catch basin

What we discovered confirmed the root cause of the backup issues.

What We Found

During excavation and inspection, we found that the secondary dry well/catch basin was completely full of water and no longer dispersing properly. This meant wastewater had nowhere to go, causing the system to back up.

In addition, the outlet pipe appeared to be pitched uphill toward the dry well rather than flowing downhill with gravity as intended. Even a slight improper grade can create major drainage problems over time, especially in older septic systems.

The combination of:

A failing dry well
Standing water
Improper drainage slope
Aging infrastructure

created the perfect conditions for recurring septic backups.

Temporary Repairs and Safety Measures

Once the issue was identified, our crew immediately completed temporary corrective measures to stabilize the system and prepare the site for the next phase of work.

This included:

Installing a temporary 4-inch Fernco fitting repair
Supporting the outlet line with proper backfill
Marking open excavation areas for safety
Beginning the Health Department permitting process for a full septic replacement

While temporary repairs can help prevent immediate worsening, systems like this typically require a properly engineered replacement solution to fully resolve the issue long term.

Why Proper Septic Assessments Matter

One of the biggest mistakes property owners can make is attempting repeated temporary fixes without understanding the real cause of the failure.

Septic issues are not something to guess at.

Older systems throughout Northern Michigan often include outdated dry wells, improperly documented layouts, or aging components that no longer meet current standards. Without excavation and proper inspection, many of these problems remain hidden underground.

At GWJ Excavation and Site Prep, we focus on identifying the true source of the issue so property owners can make informed decisions about repair, replacement, and long-term system performance.
