What is the infrastructure stress indicator?

The infrastructure stress indicator is a heuristic 0-100 composite of housing age, state funding need, violation history, and lead evidence. It is not a probability, measured pipe condition, or forecast of breaks, pressure loss, or contamination. Green Bay's average indicator is 39/100.

Infrastructure Risk Overview

Green Bay, Wisconsin has a moderate modeled infrastructure stress level with an average heuristic indicator of 39/100. The result summarizes model inputs and does not predict service outcomes.

The infrastructure stress indicator combines source inputs for housing age, funding need, violation history, and lead evidence. It does not measure the likelihood of pipe failure, water-main breaks, or system degradation.

Infrastructure Risk Distribution

How Green Bay's 12 ZIP codes are distributed by infrastructure risk level:

33% of Green Bay's ZIP codes have high or very-high infrastructure risk. Residents in these areas should be especially vigilant about water quality and pipe condition.

Water System Age and Pipe Materials

The median home in Green Bay was built in 1980 (approximately 46 years old). Housing age is one of the strongest proxies for water infrastructure age, as service lines and interior plumbing were typically installed during construction.

Pipe material risks by era:

With 67% of Green Bay's homes built before 1986, a significant portion of residential plumbing may contain lead solder or aging pipe materials.

Carbon Monoxide & Gas Safety

The available county record contains no CO/gas incidents. The average CO risk score is 0 out of 100.

Carbon monoxide is odorless and colorless - it is the leading cause of poisoning deaths in the U.S. Risk factors include:

• Gas furnaces, water heaters, and stoves
• Attached garages
• Blocked chimneys or vents
• Portable generators used indoors

Prevention:

• Install CO detectors on every level, especially near bedrooms
• Have gas appliances inspected annually
• Never run generators, grills, or cars in enclosed spaces
• Replace CO detectors every 5-7 years

What Homeowners Can Do

Pipe Inspection

• Hire a licensed plumber to inspect your service line and interior plumbing
• Check for discolored water (brown/orange = rust; white/cloudy = air or sediment)
• Test water pressure - low pressure may indicate buildup in aging pipes
• Look for visible corrosion on exposed pipes in basement or utility areas

Water Heater Maintenance

• Flush your water heater annually to remove sediment
• Check the anode rod every 2-3 years (prevents tank corrosion)
• Set temperature to 120F to prevent scalding and reduce energy use
• Replace water heaters older than 10-15 years proactively

CO Detector Placement

• One detector per floor, minimum
• Within 10 feet of each bedroom door
• Near attached garage and utility room
• 5 feet above the floor (CO rises with warm air) or on the ceiling
• Not near windows, doors, or HVAC vents (air movement causes false readings)
