Traditional cleaning processes meant that water towers and drinking-water reservoirs had to be emptied and manually cleaned or divers sent down. In both options, the reservoir has to be taken offline which can lead to major disruption to public water supply.
With our underwater cleaning robot, we can clean the drinking-water reservoir while the reservoir remains in service. The robot is remote controlled and equipped with rotating brushes and a pump that directly pumps out the sediment from the base of the reservoir.
A full video & report on the cleaning is provided to the customer on DVD for their documentation records.
Sediment that builds up at the base of a reservoir can harbour dangerous chemicals and contamination. Cryptosporidium spores for example can remain in egg form for up to two years before hatching to cause an outbreak.
Cleaning rate:
The cleaning rate will depend on the sediment depth. For a sediment depth of a half inch or less the average cleaning rate will be 90 sq meter per hour.

Machine fits through 600mm hatch.
Pumps 300-950 litres/min
Fully controlled from external station
