Stage 1:
Mechanized Dewatering:
The manhole and surroundings are cleaned off dirt, mud and algae. Excess water is drained out and flushed straight into the drainage system, leaving no mess.

Stage 2:
Sludge Removal:
The tank is completely drained off sludge and cleaned with fresh water.

Stage 3:
High Pressure Cleaning:
At this stage, the tank is thoroughly cleansed including the ceiling, the side walls and the floor, leaving no speck of dirt, algae, moss, bacteria or calcinations.

Stage 4:
Vacuum Cleaning:
A vacuum pump is used to further remove any sludge or sedimentation ensuring the tank is absolutely dirt free.

Stage 5:
Anti-Bacterial Spray:
Specially developed antibacterial agents are used to disinfect the tank and keep it protected from bacterial attack.

Stage 6:
UV Radiation:
In the sixth stage, sterilization and disinfection is done using a specially developed UV Radiator. The UV radiation kills any bacteria floating or remaining in the tank.
