Water hygiene and ozone science.

If a tank clean is just a scrub-and-rinse, it's missing the part that actually matters most for hygiene. Biofilm, a thin, sticky layer of bacteria that bonds to tank walls, survives ordinary scrubbing, which is why a "cleaned" tank can still test poorly for contamination.

A side-by-side comparison of how each method actually performs on a water tank, residue, resistant pathogens, kill speed, certification and taste.

Every Ozone Wash™ clean includes a before/after water test across 6 parameters. Here's what each one actually measures, in plain terms, using real results from an independent NABL-accredited lab report as examples.

Most claims about tank water quality in Hyderabad are anecdotal. This one isn't, it's a full before/after breakdown from an independent, NABL-accredited lab (Terra Environ Labs Pvt. Ltd.), tested across 22 physicochemical parameters, verified against the Indian drinking water standard, IS 10500:2012.

Short answer: yes. Ozone (O₃) is a stronger disinfectant than chlorine, and unlike chlorine it decomposes back into ordinary oxygen within minutes of use, no chemical residue is left behind in the water. It's the same technology used in most bottled mineral water plants in India, applied here to the tank sitting on your roof or underground.

For a standard household tank (up to 10,000 L), a single clean costs ₹3,500. A Monthly AMC costs ₹29,400 for the year, that's ₹2,450 per visit across 12 cleans, a 30% saving per clean versus paying one-time every month. All prices include 18% GST. Here's the full breakdown, and when AMC actually makes sense versus when it doesn't.

Here's the honest number, up front: a one-time clean for a standard household tank (up to 10,000 L) costs ₹3,500, inclusive of 18% GST. Larger tanks and recurring AMC plans cost less per clean. The full breakdown is below, by tank size.

Discoloured water, a musty smell, visible particles, here are seven clear signs your tank is overdue, and what each one actually means.

If you're on an RWA committee scheduling a tank clean for your community, this is the checklist to circulate, covers what needs to happen before the crew arrives, what to tell residents, and what to expect during the visit.

The short answer, by property type, followed by what the law actually says, which is probably not what you have heard.

Every completed service generates a digital, QR-signed hygiene certificate, not a generic "job done" note, but a specific, verifiable record of what actually happened during your clean. Here's what's on it and why each field is there.

Ozone Wash™'s tank cleaning process is protected under a filed patent application . Here's exactly what happens during the 8 steps that make up every base clean.

EcoScore™ is a 0–100 hygiene rating, generated automatically after every service, that converts what actually happened during your clean, not a guess, not a star rating, into a score, a badge, and a plain-English explanation of exactly why you got it.

Water hygiene is an easy thing to overlook until an FSSAI inspection asks for proof of it. If your kitchen relies on a storage tank, overhead, underground, or both, here's what documented compliance actually looks like, and how it fits into a routine inspection.

You'll find a lot of vague claims online about a specific legal requirement to clean water tanks "every 3 months" in Hyderabad. Here's the precise, source-checked answer: that specific frequency isn't written into the GHMC Act itself. What the law does say is more interesting, and arguably more important to understand.

That damp-towel smell when you turn the AC on isn't the cabin filter. It's mould growing inside the evaporator. Ozone gets in where wipes can't.

A traditional wash uses ~50 litres per car. We tested ours: 2.8 L average. Here's the breakdown, and what it means for your building's water bill.

Ozone sounds chemistry-class scary. The science is actually simpler than chlorine, and it's used in every bottled mineral water plant in India.

If you've ever tried to bring a wash van into your apartment complex, you know the story. Here's why, and the alternative most RWAs already approve.

Fabric seats absorb sweat, food crumbs, kids' juice, and skin cells. Vacuums only get the top layer. Here's what 120°C steam reaches.
