Tank Disinfection & Chlorination in Delhi NCR

What should never go into a drinking-water tank

Bleaching powder by the handful, phenyl, floor cleaner, detergent and acid. All five are common in the cheap end of the Delhi market. Unmeasured bleaching powder is either ineffective or leaves water harsh; phenyl and detergent leave residue that leaches for weeks; acid attacks RCC and metal fittings and has no place in a vessel you drink from.

Contact time is the step people skip

A disinfectant sprayed on and immediately rinsed off has not disinfected anything. Every approved product has a stated contact time on wetted surface, and skipping it is the most common way a technically correct chemical produces a technically useless result.

Chlorine is not the problem

Measured chlorination is how municipal supply is protected worldwide. The problem is never chlorine — it is unmeasured chlorine. Dose calculated from volume gives you residual protection without the taste and smell people associate with over-treatment.

Frequently Asked Questions

Is disinfection charged separately?

Anti-bacterial disinfection is included in every clean. Additional measured chlorination and UV sterilisation are priced as add-ons.

Is it safe for children and pets?

Yes, at the doses used and after normal refill. Water is safe to use about an hour after the tank is refilled.
