Overhead and underground tanks collect sediment, rust flakes and biofilm long before residents see or smell anything wrong. In older societies, tanks often go years between proper cleans — because getting a crew, machines and access sorted is a hassle nobody wants to own.

The same sequence every time, so your society gets a consistent, verifiable result — not a quick rinse.
The manhole and surroundings are cleaned of dirt, mud and algae. Water below the foot-valve level is then pumped out using special de-watering equipment.
Sludge settled on the tank floor is sucked out completely using our special sludge-pumping equipment.
Walls and ceilings are thoroughly cleaned with high-pressure jet cleaners, removing deposits, algae and contaminants that let microbial growth take hold.
An industrial vacuum cleaner removes the resultant contaminants, leaving the tank absolutely speck-free.
Walls and ceilings are made totally sterile from bacterial contamination using specially developed anti-bacterial agents.
Final sterilization and disinfection is done using a specially developed UV radiator, killing any suspended or floating bacteria remaining in the tank.

At a residential building in Kasba, the underground reservoir hadn't been opened for cleaning in a long time. A water sample pulled straight from the tank came out visibly discoloured — a clear sign of sediment and contamination building up out of sight.
Our team ran the full 6-stage mechanized clean on site: de-watering, sludge removal, high-pressure jet cleaning, vacuum extraction, anti-bacterial treatment and UV radiation sterilization. The tank was left clean, sterile and ready to refill the same day.
