“Called them at 9 AM, tank was sparkling by 11:30 AM. The before-and-after photos they sent on WhatsApp were shocking — so much sludge we had been drinking. Would never go anywhere else.”
Underground Tank
Underground Water Tank & Sump Cleaning
The underground sump is where every sediment eventually settles. If you haven't cleaned it in 18 months, you are drinking filtered sludge. Our confined-space certified team safely de-sludges tanks up to 50,000L with oxygen monitoring and blower ventilation.
Scope of service

No unclear handovers, no “we didn't know about that” confusion. Here's exactly what is included in every single underground tank job.
- Confined-space risk assessment
- Continuous oxygen monitoring

- Fresh-fill and chlorination advisory

Inspection
HandoverPhoto proofSigned reportService notes
- 01
Inspection & scope check
A technician checks your tank size, material, access and water quality, then confirms the service scope and slot on WhatsApp.
- 02
Drain & isolation
We isolate your inlet and outlet, drain the remaining water safely into your garden or storm line, and protect the float valve and pipe openings.
- 03
Mechanised scrubbing
Our 120-bar high-pressure jet cleaner scrapes off bio-film, scale, algae and rust. The material-specific brushes protect RCC, Sintex and plastic walls alike.
- 04
Vacuum & residue removal
An anti-bacterial wet-dry vacuum lifts every trace of sludge and dirty water out of the tank, so you never flush contaminants into your supply line on re-fill.
- 05
Food-grade sanitisation
NSF-approved sanitiser plus a silver-ion finishing mist kill E. coli, Legionella and Giardia. Gaskets re-sealed, lid locked, ready to fill.
- 06
Photo report & handover
We send you a before/after photo report on WhatsApp, share service notes for your records, and provide refill guidance before the tank goes back into use.
Underground Tank FAQs
The questions we hear most about this service.
Is it safe to clean an underground tank with people inside?
+
Only with proper protocols. Our crew carries ISA-standard oxygen monitors, SCBA masks when required, and we always position a stand-by technician topside. We never send anyone into a tank that has had chemicals stored in it without full confined-space hazard clearance.

after the clean.
Feedback themes from residential, society and commercial tank-cleaning enquiries across Ahmedabad.
“We've been on their AMC for 2 years. The service report they hand over after every quarterly clean goes straight into our NABH file. Professional, punctual and well documented.”
“6 wings, 180 flats — they finished the whole society in a single weekend. One invoice, one WhatsApp group, zero hassle. Our residents have been asking for 'Hariommhar' ever since.”
“We needed after-hours service before an FSSAI inspection. They came at 11 PM, finished by 2 AM, and the signed report was ready for our inspector at 10 the next morning.”
“Our 50 KL RO tank had 3 years of scale. They came with a 6-person crew and full PPE, finished in 7 hours during our Sunday shutdown. Zero production loss.”
“My mother-in-law was worried about chemicals. They patiently showed her the food-grade certificate and let her smell the water after cleaning. No complaints since.”
