When was the last time you cleaned your water tank? If you can't remember, your family might be drinking contaminated water right now. In Bangalore, where most homes rely on a mix of BWSSB supply, borewell water, and tanker water, regular tank cleaning isn't a luxury — it's a health necessity.
What Happens Inside a Dirty Water Tank?
Over time, your water tank accumulates sediment (sand, mud, rust particles), algae growth (especially in tanks exposed to sunlight), bacterial colonies (E. coli, Salmonella, Legionella), organic matter from dead insects, bird droppings (for overhead tanks), and mineral scaling from hard water.
This contamination happens gradually, so your water may look clear even when it carries harmful bacteria. The risk is highest for families with young children, elderly members, or anyone with compromised immunity.
How Often Should You Clean?
Health experts and BWSSB recommend cleaning water tanks every 3 to 6 months. If you use borewell or tanker water, clean every 3 months. If you use only BWSSB supply, every 6 months is sufficient. During monsoon season, consider an additional cleaning due to higher contamination risk.

What Does Professional Tank Cleaning Include?
A proper professional tank cleaning service should include complete water draining, manual scrubbing of all interior surfaces, high-pressure jet washing for stubborn deposits, anti-bacterial chemical treatment, UV sanitisation (for premium services), and a before/after photo report with completion certificate.
AMC Plans — The Smarter Choice
Instead of booking one-off cleanings, consider an Annual Maintenance Contract (AMC). You get 2-4 scheduled cleanings per year at a 20-30% discount, automatic reminders, priority scheduling, and certified reports for your records. For apartment associations managing multiple tanks, AMC plans make budgeting simple and ensure consistent water quality for all residents.
What to Look For in a Tank Cleaning Service
- Do they use anti-bacterial treatment (not just scrubbing)?
- Do they provide before/after photo documentation?
- Are their chemicals FDA-approved and safe for drinking water tanks?
- Do they offer UV sanitisation?
- Will they provide a written service report/certificate?
