Traditional manual scrubbing leaves algae, bacteria, and toxic sludge behind. SGS uses specialized machinery and non-toxic antibacterial treatments.
Emptying leftover dirty water using heavy-duty submersible sludge pumps, preserving existing water if pre-planned.
Industrial suction extractors remove heavy sludge, mud, sediments, and organic waste settled at the tank floor.
German high-pressure rotary jets strip away stubborn algae, scale, fungus, and bio-film from walls and ceiling.
Industrial wet-vacuuming removes every trace of dislodged debris, dead microbes, and contaminated wastewater.
Eco-friendly, food-grade antimicrobial sanitization kills 99.9% of bacteria, viruses, and pathogens with zero residual odor.
Ultraviolet radiation treatment ensures floating airborne spores and microscopic germs are permanently deactivated.

Transparent answers about our water tank cleaning process, pricing, and timing.
According to health guidelines and Bengaluru water conditions, water tanks and underground sumps should be cleaned at least once every 6 months. In areas dependent on borewell water or tanker water with high TDS and sediment, quarterly cleaning (every 3 to 4 months) is recommended.
For a standard domestic tank (500L to 1,500L), the entire mechanized process takes approximately 45 to 60 minutes. An underground sump (3,000L to 6,000L) takes around 1.5 to 2 hours.
Yes, 100%! We use certified eco-friendly, food-grade antimicrobial sanitizers that leave zero chemical residue, bad odor, or toxic aftertastes. Tanks are safe to fill and use immediately after our final UV sterilization step.
We advise customers to consume or pump down the water level before our appointment to avoid wasting clean water. Any remaining water at the bottom with sediment is pumped out using our high-speed dewatering pumps.
