The 6 Major Health Risks of Poor Residential Sewage Handling

Untreated or poorly managed household wastewater creates serious threats to family health that many homeowners in India still underestimate. Without reliable sewage treatment solutions, pathogens, toxic gases, and vectors spread unchecked, turning everyday residential spaces into hidden disease hotspots. Understanding these six major risks highlights exactly why investing in proper onsite treatment has become essential for long-term well-being.

Risk 1: Waterborne Bacterial Infections

Bacteria like E. coli, Salmonella, and Vibrio cholerae flourish in untreated sewage. These microbes cause diarrhea, cholera, and typhoid fever. Symptoms include severe dehydration, abdominal cramps, and fever.

In India, about 37.7 million people suffer from waterborne diseases each year, per UNICEF estimates. Children under five are particularly vulnerable. For instance, in 2015, over 117,000 such children died from diarrheal diseases linked to polluted water.

Urban slums in Kolkata often report outbreaks during floods. Stagnant sewage mixes with rainwater, contaminating wells. Consequently, hospitalization rates spike. Preventive measures, however, can reduce these incidents dramatically.

Risk 2: Viral Diseases from Contaminated Water

Viruses such as Hepatitis A and Norovirus spread via sewage-tainted sources. These lead to liver inflammation, gastroenteritis, and prolonged fatigue. Jaundice and nausea commonly appear.

The National Family Health Survey indicates rising diarrhea cases in cities like Delhi, from 15,152 in 2022-23 to 20,393 in 2023-24. Poor sewage handling exacerbates this trend. Rural areas face similar issues with open drains.

Exposure happens through drinking or bathing in affected water. In addition, food washed with contaminated supplies transmits viruses. Thus, community health suffers broadly.

Risk 3: Parasitic Infestations

Parasites like Giardia and Cryptosporidium thrive in raw sewage. They cause giardiasis and cryptosporidiosis, resulting in chronic diarrhea and malnutrition. Weight loss and stunting in children follow.

Studies from the Tata Institute of Social Sciences reveal high tuberculosis and dengue cases near Mumbai landfills. Untreated waste breeds vectors. In eastern India, similar patterns emerge in flood-prone zones.

Long-term effects include weakened immunity. Moreover, repeated infections hinder child development. As such, addressing sewage is crucial for nutritional security.

Risk 4: Respiratory Complications from Toxic Gases

Sewage decomposition releases methane, ammonia, and hydrogen sulfide. These gases irritate lungs, causing asthma exacerbations and bronchitis. Dizziness and headaches also occur.

In Ghazipur landfill near Delhi, methane emissions reached 2.17 metric tonnes per hour in 2022, per Bloomberg. Nearby residents report breathing difficulties. Urban India sees rising respiratory illnesses tied to waste sites.

Furthermore, airborne pathogens spread during dry seasons. Transitions to cleaner air require proper ventilation and treatment. Otherwise, chronic conditions develop.
