Tank & Chamber
Cleaning
Septic tanks, sumps, STP and ETP tanks, inspection chambers and wet wells: HYVAX empties and cleans them with industrial vacuum from outside the tank. Nobody climbs in, the waste goes straight into a sealed tank, and the site is left clean.
What We Clean
Every Tank, Cleaned From Outside
Sludge and settled solids build up in every tank that handles wastewater. Left alone, they reduce working volume, block outlets and create odour and gas. We remove the full contents (liquid, sludge and settled grit) with suction lines lowered in from above.
No Confined-Space Entry
Suction hoses do the work from the surface. Workers stay out of the tank and away from toxic gas and oxygen-poor air.
Full Contents Removed
Liquid, floating scum, sludge and bottom grit are all extracted, restoring the tank's working volume.
Sealed Transport
Everything goes directly into our sealed vacuum tank. No open buckets, no spills on site.
Clean Handover
Walls and floor are washed down so you can inspect, repair or put the tank straight back into service.
The Process
How We Clean
A Tank
A planned, sealed and documented job, from opening the first cover to handing back a clean tank.
Stage 01
Site & Tank Assessment
We confirm the tank type, size, access points and contents, and plan the vehicle position and hose routing.
Stage 02
Safety Setup
The area is barricaded, covers are opened in sequence and the tank is ventilated before work begins.
Stage 03
Vacuum Extraction
Liquid and sludge are drawn out through suction lines lowered from the surface into the sealed tank.
Stage 04
Jetting & Final Suction
High-pressure water loosens settled solids from the walls and floor, and the slurry is vacuumed out.
Stage 05
Disposal & Handover
Waste is transported for responsible disposal and the tank is handed back clean and ready for inspection.

Where We Work
Tanks We Clean
If it holds wastewater, sludge or settled solids, we can empty it and clean it.
Why It Matters
Safer.
Cleaner.
Complete.
Manual tank cleaning puts people inside confined spaces with toxic gases. Vacuum cleaning removes that risk entirely and does a more thorough job.
No Workers Inside
The biggest risk in tank cleaning is entry. Our method removes it.
Restored Capacity
Full removal of sludge and grit returns the tank to its working volume.
Odour Control
Sealed extraction keeps smell and spillage away from the surrounding site.
Ready for Inspection
A washed-down tank lets your engineers check its condition properly.
Frequently Asked
Common Questions
Septic tanks, STP and ETP tanks, sumps, wet wells, inspection chambers and similar tanks. Tell us the tank type and size and we'll confirm the approach.
No. Suction and jetting hoses are lowered in through the access opening, so the work is done from outside.
Often, yes. We plan the work around your flows, and at treatment plants we agree the sequence with your operators.
It is held in our sealed vacuum tank and transported for responsible disposal.
Yes. HYVAX serves Ernakulam and surrounding districts across Kerala. Contact us with your site location and we'll confirm coverage and mobilisation timing.
