How Dirty Water Tanks Affect Your Health (And How to Fix It)
Water is essential to life — but only if it’s clean. What many families don’t realize is that the cleanliness of your water isn’t just about the source — it’s also about where it’s stored. Over time, water tanks collect dirt, algae, rust, sediment, and harmful microbes. Without regular water tank cleaning, the water you use for drinking, bathing, and cooking may be making you sick.
Let’s explore the hidden dangers of dirty tanks, how they affect your health, and how Sajilo Sewa’s professional water tank cleaning services in Kathmandu Valley can help you fix it.
🚨 What Happens Inside a Dirty Water Tank?
Over time, your water tank silently collects:
Dirt and debris from rainwater or impure municipal supply
Algae and moss due to sunlight and moisture
Rust and scaling from old pipes and tank material
Bacteria, viruses, and parasites that multiply quickly in stagnant water
This contamination is invisible to the naked eye — but the effects on your health are very real.
🚱 The Health Risks of a Dirty Water Tank
If not cleaned regularly, water tanks become breeding grounds for various harmful contaminants. Here’s how they affect your health:
1. Waterborne Diseases
Contaminated water from tanks can cause:
Diarrhea
Typhoid
Cholera
Hepatitis A
Dysentery
Skin and eye infections
Children, the elderly, and those with weak immune systems are especially at risk.
2. Digestive and Intestinal Issues
Water used for drinking and cooking may carry harmful microorganisms that lead to bloating, stomach cramps, nausea, and indigestion.
3. Allergies and Skin Reactions
Using contaminated water for bathing, washing, or cleaning can cause rashes, itching, and allergic reactions.
4. Bad Odors and Taste
Build-up of algae and rust causes water to develop a foul smell or metallic taste, making it unfit for daily use.
🧽 Common Sources of Contamination in Kathmandu Homes
Uncovered rooftop tanks that collect dust and insects
Poorly maintained underground tanks with mud and leakage issues
Use of non-sterilized pipes and plumbing
Irregular water supply mixed with untreated sources
Lack of routine maintenance and inspection
With these risks, it becomes essential to choose a reliable service provider for hygienic water tank cleaning in Kathmandu.

📍 Why Water Tank Cleaning is Essential in Kathmandu
In the Kathmandu Valley, water often comes from mixed sources — municipal supply, borewells, rainwater, or tanker delivery — which can contain pollutants. In many areas, tanks are not sealed properly, making them vulnerable to dust, insects, and algae.
With rising health concerns and increasing cases of waterborne diseases, choosing a professional like Sajilo Sewa for water tank cleaning in Kathmandu is more important than ever.
