Yes, sewage is extremely harmful to humans. It carries dangerous bacteria, viruses, and parasites that can lead to serious illnesses. From respiratory infections to skin diseases and even life-threatening conditions like hepatitis, exposure to untreated sewage isn’t just unpleasant—it’s a major health hazard.
Sewage issues are also linked to plumbing problems like low house water pressure, pipe blockages, and leaks. These problems are on the rise in many areas, and Phoenix plumbers today often warn homeowners in California about the risks of ignoring signs of sewage leaks or backups.
What Is Sewage?
Sewage is a mix of wastewater from toilets, sinks, showers, laundry, and industrial systems. It contains:
-
Human waste
-
Food scraps
-
Chemicals and soaps
-
Pathogens like E. coli and Salmonella
-
Parasites and viruses
When not properly contained or treated, sewage becomes a serious public health threat. Broken sewer lines, backflow, and faulty drainage systems can bring this toxic waste right into your home.
Health Risks of Sewage Exposure
Exposure to raw sewage—either through water or air—can cause a range of illnesses, including:
1. Gastrointestinal Infections
Stomach cramps, vomiting, diarrhea, and fever are common after contact with contaminated water.
2. Skin and Eye Irritation
Direct contact with sewage can cause rashes, burns, and eye infections.
3. Respiratory Problems
Sewage gases like methane and hydrogen sulfide can trigger breathing issues, headaches, and fatigue.
4. Hepatitis A
A highly contagious liver disease that spreads through contact with fecal matter in sewage.
5. Leptospirosis
A bacterial infection that can enter the body through cuts or mucous membranes when exposed to sewage.
Common Plumbing Causes Behind Sewage Problems
Sewage issues usually arise from underlying plumbing problems. These problems often affect water flow and pressure in your home.
✅ Blocked Sewer Lines
Grease, debris, and foreign objects can clog sewer lines, leading to backups and low house water pressure.
✅ Tree Root Intrusion
Roots can grow into pipes, cracking them and allowing sewage to leak underground.
✅ Aging Infrastructure
In cities with older homes like Oakland, Fresno, and San Francisco, outdated pipes are more likely to fail.
✅ Corroded Pipes
Metal pipes corrode over time, creating cracks where sewage can escape.
✅ Broken or Collapsed Pipes
In places like San Jose and Los Angeles, ground movement from earthquakes or soil erosion can cause pipe failure.
Signs You May Have a Sewage Issue
Be alert for early signs of sewer problems, especially if you’re experiencing:
-
Low house water pressure
-
Gurgling sounds from drains
-
Bad odors near plumbing fixtures
-
Sewage water backing up into toilets or tubs
-
Wet spots or lush patches in your yard
If you see these signs, don’t wait. Call a plumber immediately. Phoenix plumbers today often use camera inspections to quickly diagnose the cause without digging.
California Cities with Frequent Sewage Problems
Due to aging infrastructure, population growth, and natural events like earthquakes, several California cities experience recurring sewage and water pressure issues:
-
Los Angeles – aging sewer systems and population density
-
San Francisco – outdated clay pipes and hilly terrain
-
Fresno – high mineral content and pipe corrosion
-
San Jose – root intrusion and shifting soil
-
Sacramento – ground movement and pipe misalignment
-
Oakland – wet weather and overwhelmed drainage systems
These cities often require professional sewer inspections, especially when low house water pressure is present.
Why Phoenix Plumbers Today Emphasize Early Detection
In areas like Phoenix, plumbers are increasingly using trenchless technology and modern inspection tools to identify sewage issues before they become health emergencies. They emphasize the need for fast action when water pressure drops or backups occur.
Professional plumbers know how to:
-
Identify sewage leaks using video cameras
-
Recommend safe, cost-effective repairs
-
Prevent the spread of contamination
-
Restore normal water flow and pressure
If you live in a high-risk area or an older home, it’s essential to schedule regular plumbing inspections.
How to Prevent Sewage Exposure
You can reduce your risk of exposure by staying proactive about your plumbing system. Here’s how:
✔ Maintain Drainage
Avoid pouring grease, coffee grounds, or heavy food scraps down the drain. These clog your system and slow down water flow.
✔ Install Backflow Valves
These prevent sewage from backing up into your home during a pressure drop.
✔ Replace Old Pipes
If your home has old clay or metal pipes, consider upgrading them to modern PVC or trenchless liners.
✔ Regular Inspections
Schedule routine plumbing checks—especially if you’re in cities like San Diego, Fresno, or Phoenix.
What to Do if You Suspect Sewage Contamination
-
Leave the Area Immediately
Avoid any contact with sewage or standing water. -
Turn Off Water Supply
Shut down your home’s water to prevent further backup. -
Call a Professional Plumber
Reach out to licensed plumbers like phoenix plumbers today who offer 24/7 emergency response. -
Avoid Using Toilets and Sinks
