Is Sewage Water Dangerous? Health Risks Explained

Sewage water is dangerous because it is Category 3 black water containing raw waste, microbes, chemicals, and toxic gases. Most sickness comes from skin contact or breathing mist during a backup. Exposure can trigger stomach illness, skin infection, and breathing issues, and it can taint building materials. Professional cleanup is required; trained crews use protective gear, advanced extraction, and hospital-grade disinfectants. Colorado Cleanup Services performs this work around the Denver area with IICRC-certified protocols and 24/7 response.

Act fast if you notice any of the following:

• Standing water that smells like sewage or shows solids.
• Multiple fixtures backing up or wastewater on the lowest level.
• HVAC running that could carry contamination to clean rooms.

Avoid contact, turn off HVAC in the area, and wait for technicians to handle removal and sanitation. <br/> Updated: 2026-05-07 <br/> Need help in Lakewood, CO? Call (303) 237-4406 or book online.
