What is infrastructure decay probability?

Infrastructure decay probability estimates the likelihood of water pipe deterioration based on pipe age, material type, violation history, and environmental conditions. Higher probability means greater risk of water main breaks, pressure drops, and contamination from aging pipes. The national average hovers around 30-40%. Sugar Grove's average is 22%.

What are CO/gas incidents?

Carbon monoxide (CO) and gas incidents tracked by the NTSB include pipeline failures, gas leaks, and CO exposure events. CO is odorless and can be fatal — the CDC reports about 420 deaths annually from unintentional CO poisoning. Every home should have working CO detectors on each floor, tested monthly. Sugar Grove has 5 recorded incidents in the NTSB database.

Water System Age and Pipe Materials

The median home in Sugar Grove was built in 1991 (approximately 35 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:

Carbon Monoxide & Gas Safety

5 CO/gas incidents have been recorded in the county covering Sugar Grove. The average CO risk score is 4 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)
