Why an AI-Assisted Reassessment Was the Smart Choice for Macomb County

The Challenge

Macomb County, Michigan is responsible for maintaining the health and integrity of a significant sewer infrastructure network serving communities across the county. To assess the condition of its system, the county undertook a traditional, manual NASSCO PACP condition assessment — the standard approach used by utilities and municipalities across the country. But when the results came back, Macomb County's internal team had questions.

The recommendations from the assessment included a substantial list of repairs flagged as immediate priorities — work that would carry a significant cost. Rather than accept the findings at face value, the county's operations team decided to take a closer look. Their instinct that something wasn't right would prove to be worth more than a million dollars.

The Decision to Reassess

Macomb County turned to SewerAI — the leading platform for infrastructure management — to conduct an AI-powered reassessment of the same data. Using AutoCode, SewerAI's AI computer vision technology, the county sought a fresh, independent look at the inspection footage that had generated the original recommendations.

The decision to use AI for a reassessment rather than simply commissioning another manual review was deliberate. AutoCode applies consistent, objective coding logic to every foot of footage — eliminating the variability and potential for error that can affect manual assessments. If the original results were flawed, AutoCode would find it.

Results

$1 Million Saved in 24 Hours

The impact was immediate and dramatic. Within 24 hours of analysis, AutoCode had reassessed the data and delivered findings that directly contradicted a significant portion of the original recommendations. Repairs that had been flagged as immediate priorities were found to be misclassified — saving Macomb County more than one million dollars in work that was not, in fact, urgently needed.

At the same time, AutoCode uncovered critical defects that had been missed entirely in the original manual assessment — conditions that required genuine attention and that the county would not have known about had they simply accepted the first report.

Better Data. Better Decisions.

The Macomb County reassessment is a clear illustration of what is at stake when condition assessment data is inaccurate. Municipalities make capital planning decisions — decisions involving millions of dollars and years of work — based on the data their assessments produce. When that data is wrong, the consequences are real: money spent on unnecessary repairs, critical issues left unaddressed, and communities left with infrastructure that isn't being managed as effectively as it could be.

By turning to SewerAI, Macomb County was able to correct the record, protect its budget, and ensure that its rehabilitation priorities were based on accurate, AI-validated data.

In Their Own Words

"Questioning some of the recommendations we received from a recent assessment project, we turned to SewerAI's AutoCode to reassess the data. Their swift action not only saved us over a million dollars in repairs previously recommended as immediate, but also uncovered critical defects within 24 hours of analysis — information missed in the original assessment. Working with SewerAI has been incredibly satisfying, and we're eagerly anticipating future collaborations."

A Platform Built for What's at Stake

Half of the nation's sewer infrastructure is failing. It is a $1.6 trillion problem spanning more than six billion feet of sewer pipe — and it requires wastewater professionals to continually assess, prioritize, and act on the condition of their systems. The margin for error is narrow, and the consequences of bad data are significant.

SewerAI is the only wastewater platform built by wastewater professionals. Designed to give municipalities and utilities superhuman speed and accuracy, SewerAI's AutoCode meets NASSCO PACP and other industry standards while dramatically increasing the productivity of every team it touches. With just one hour of training and seamless software integration, it accelerates project timelines, reduces labor hours, and frees up teams to focus on what they do best.

For Macomb County, the platform delivered exactly what it promises: better data, better decisions, and results that speak for themselves.
