Brown sludge settles at the base of your tank over months, reaching every tap in your home.
Uncleaned tanks breed E.coli and harmful bacteria — invisible, but a serious health risk for your family.
Health guidelines recommend cleaning overhead tanks and underground sumps every 6 months minimum.
Complete water extraction using a submersible pump. Tank fully emptied before cleaning begins.
High-pressure scrubbing of all interior walls and floor. Every patch of algae and biofilm removed.
Food-grade chlorine treatment throughout. Safe for drinking water — the same standard used in municipal water treatment.
We show you photos of the sludge removed. You see the result before we leave.
| Tank Type | Starting From |
|---|---|
| Overhead tank | ₹800 |
| Underground sump | ₹1,200 |
| Large apartment sump | ₹2,000+ |
