How Often Should You Clean Your Water Tank? A Guide for Indore Homes

Most Indore homes store water in a rooftop plastic tank, an underground sump, or both. Because the lid is rarely opened, it is easy to forget that the tank needs cleaning. But every litre of water that enters it carries a little sand, silt and organic matter — and it all settles at the bottom.

The short answer: every 3 to 6 months

For most households, cleaning the water tank every 3 to 6 months keeps it safe. Clean it more often if:

• You use borewell or tanker water
• The water looks cloudy, yellow or has particles
• You notice a smell or taste
• The monsoon has just ended
• Someone at home has frequent stomach problems

Why a dirty tank is a health risk

Sludge at the bottom of a tank is a breeding ground for bacteria, and warm rooftop tanks in Indore summers encourage algae growth. This water is used for bathing, washing utensils and — in many homes — cooking. Contaminated tank water is a common cause of stomach infections, skin irritation and clogged taps and RO filters.

The correct tank cleaning process

• Close the inlet and use up or store the remaining water
• Drain the tank completely
• Remove sludge and sediment manually
• Scrub walls, floor and lid with brushes
• Vacuum out the dirty water
• Disinfect the tank and rinse before refilling

DIY or professional?

You can clean a small, easily reachable tank yourself, but it involves climbing, working in a confined space and handling disinfectants. Underground sumps and large society tanks should always be cleaned by trained professionals with the right safety equipment.
