Monsoon drinking water safety in Kottayam: wells, boiling and jars
During heavy rain, surface water can seep into open wells and leaking pipes, raising the risk of water-borne illness. In the monsoon, boil well or tap water at a rolling boil for at least one minute, store it covered, and clean storage containers often — or switch to sealed packaged water for drinking until the water runs clear again.
Kottayam gets heavy south-west monsoon rain from June to September and more rain with the north-east monsoon in October and November. Low-lying areas near the backwaters and rivers see flooding most years. That is exactly when household water is most at risk.
Why the monsoon affects drinking water
- Run-off carries soil, animal waste and septic overflow into open wells.
- Pipe joints and tanks that are not sealed let dirty water in.
- Flooded areas can contaminate borewells and storage tanks.
- Muddy water clogs home filters and RO membranes faster.
Simple steps that work
- Boil water for drinking at a rolling boil for at least 1 minute, then let it cool covered.
- Store drinking water in a clean container with a lid and a tap, so hands do not go into the water.
- Clean storage containers and dispensers every week in the rainy season.
- After flooding, get your well chlorinated before using the water again — your local health centre or panchayat can advise.
- If water looks muddy or smells unusual, do not rely on a home filter alone.
When packaged jar water makes sense
Sealed packaged water is a practical option for drinking and cooking while well water is muddy or after flooding — especially for babies, older people and anyone unwell. Check the seal, label and FSSAI number on every jar.
If anyone at home has diarrhoea, vomiting or fever after drinking water, see a doctor and inform your local health centre. This guide is general information, not medical advice.

Frequently asked questions
Is it safe to drink well water during the monsoon?
Well water is more likely to be contaminated during heavy rain and flooding. Boil it at a rolling boil for at least one minute before drinking, or use sealed packaged water until it runs clear.
How long should I boil water to make it safe?
Bring it to a rolling boil and keep it boiling for at least one minute, then cool it in a covered, clean container.
Can I use an RO purifier with muddy monsoon water?
Muddy water clogs pre-filters and membranes quickly, which can reduce performance. Many families use packaged water for drinking during these weeks and service the purifier afterwards.
