Infrastructure Risk in Dearborn Heights, MI: High
Decay risk 50% · high · 1 water system · Updated 2026-05-03
Dearborn Heights's infrastructure has high decay risk. Aging pipes and systems may be prone to failures.
Data: EPA ECHO, Census ACS, NTSB Last verified: 2026-05-03
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%. Dearborn Heights's average is 50%.
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. Dearborn Heights has 32 recorded incidents in the NTSB database.

Water System Age and Pipe Materials
The median home in Dearborn Heights was built in 1952 (approximately 74 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:
| Era | Common Pipe Material | Expected Lifespan | Key Risk |
|---|---|---|---|
| Pre-1940 | Lead, cast iron | 50-75 years | Lead contamination, corrosion |
| 1940-1960 | Galvanized steel, cast iron | 40-60 years | Rust, lead solder, reduced flow |
| 1960-1980 | Copper, galvanized steel | 50-70 years | Lead solder (pre-1986), pinhole leaks |
| 1980-2000 | Copper, PVC, CPVC | 25-50 years | Chlorine degradation of plastics |
| 2000+ | PEX, copper, CPVC | 25-50+ years | Generally low risk |
With 94% of Dearborn Heights's homes built before 1986, a significant portion of residential plumbing may contain lead solder or aging pipe materials.
Carbon Monoxide & Gas Safety
32 CO/gas incidents have been recorded in the county covering Dearborn Heights. The average CO risk score is 46 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)
