Milwaukee County’s Infrastructure Revolution: How 2024 Sewage Treatment Upgrades Are Protecting Your Home from Costly Backups

Milwaukee County residents have long dealt with the persistent threat of sewage backups, particularly during heavy rainfall events. However, significant infrastructure improvements in 2024 are transforming the landscape of residential sewage protection, offering homeowners unprecedented relief from this costly and hazardous problem.

The Scale of Milwaukee’s Infrastructure Investment

The Milwaukee Metropolitan Sewerage District has received around $76 million from the Bipartisan Infrastructure Law for 10 projects, ranging from improvements to wastewater treatment plants to new sewer overflows. This substantial investment represents just a portion of the region’s comprehensive approach to modernizing aging sewer systems that have served the area for nearly a century.

As a region, we’ve invested more than $4 billion to reduce sewer overflows, a massive effort that is paying off. Our current financial forecast through 2035 calls for investing $3.5 billion in clean water infrastructure, flood management, and debt financing to help protect public health and Lake Michigan.

How Infrastructure Improvements Reduce Backup Risks

The 2024 upgrades focus on several critical areas that directly impact residential backup risks. Since 1994, the ISS tunnels have prevented more than 37 billion US gallons (1.4×1011 L) of combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs) from entering area waterways, including Lake Michigan. The Deep Tunnel system, a cornerstone of Milwaukee’s flood management strategy, continues to expand its capacity.

Our two water reclamation facilities, Jones Island and South Shore, efficiently clean about 150 million gallons of water on a dry day and have the capacity to clean up to 630 million gallons a day when it rains. Thanks to the deep tunnels and many other improvements, we average 2.2 overflows per year (down from 50-60) and have captured and cleaned 98.4% of the water that’s entered the regional sewer system since 1994.

Understanding the Causes of Residential Backups

For Milwaukee County homeowners, understanding what causes sewage backups is crucial for prevention. A backwater is the back-up or back flow of water due to a clog or blockage in the sewer lateral or sewer main that the lateral connects to. The clogs or blockages refer to anything preventing the gravity flow of water and waste through the building lateral or sewer main. Thus, the unfortunate occurrence is a back-up into the building’s basement or living spaces.

Common causes include clogged or damaged sewer lines, heavy rainfall overwhelming sewer systems, tree root intrusions, and aging plumbing, with regular maintenance helping prevent many issues. Milwaukee County’s infrastructure challenges make professional assessment particularly valuable.

The Role of Green Infrastructure

Beyond traditional infrastructure upgrades, Milwaukee County is embracing innovative green infrastructure solutions. The benefits of green infrastructure include: improves air quality, reduces the temperature in hot summer months, provides children with outdoor space to play and learn, makes our neighborhoods more beautiful and welcoming, and reduces pressure on storm sewers and wastewater treatment facilities.

Reducing stormwater inflow into the combined system with green infrastructure will reduce the risk of a combined sewer overflow. These solutions work hand-in-hand with traditional infrastructure to provide comprehensive protection.

What This Means for Homeowners

The infrastructure improvements significantly reduce the likelihood of sewage backups, but homeowners should remain vigilant. A single downspout connected to the sanitary sewer system can deliver up to 12 gallons a minute of excess water during heavy rain. Homes without sump pumps typically have foundation drains that are connected to the sanitary sewer system. Those can deliver up to 10 gallons a minute of excess water.

When backups do occur, immediate professional response is critical. Sewage cleanup requires specialized equipment, protective gear, and proper sanitization methods to ensure safety and prevent long-term contamination, which is why it should be left to trained professionals. The health risks are significant—raw sewage contains harmful bacteria, viruses, and pathogens that can contaminate flooring, walls, air systems, and personal belongings.

Professional Cleanup Services: Your Safety Net

Despite these infrastructure improvements, sewage emergencies can still occur. When they do, having access to professional cleanup services becomes essential. Companies specializing in Sewage Damage Cleanup Milwaukee County understand the unique challenges of the region’s aging infrastructure and can respond quickly to minimize damage and health risks.

Professional restoration companies offer comprehensive services that go far beyond simple cleanup. They possess the specialized equipment and expertise needed to safely remove contaminated materials, sanitize affected areas, and restore properties to safe, habitable conditions. Their understanding of local infrastructure challenges and rapid response capabilities make them invaluable partners for Milwaukee County homeowners.

Looking Forward: Continued Protection

We have a tremendous amount of work ahead to reduce the risk of basement backups in our region. In the next RiversReport, we’ll talk about ways to improve and a $150 million plan to address work on private property. This ongoing commitment to infrastructure improvement provides hope for even greater protection in the years ahead.

The combination of massive infrastructure investments, innovative green solutions, and professional cleanup services when needed creates a comprehensive safety net for Milwaukee County residents. While the threat of sewage backups may never be completely eliminated, the 2024 upgrades represent a significant step forward in protecting homes, health, and property values throughout the region.

For homeowners, staying informed about these improvements and maintaining relationships with qualified restoration professionals ensures the best possible protection against sewage-related emergencies. The future of Milwaukee County’s water management looks brighter than ever, thanks to these substantial infrastructure investments and ongoing commitment to resident safety.
