Diving in contaminated environments

K&C Diving possesses specific expertise for diving activities in contaminated or hyperthermic environments, both for government organisations and for private companies. K&C Diving has special equipment at its disposal for underwater works in - for example - water treatment facilities, sewers and waste water reservoirs.

If diving in sludge buffer tanks is required, K&C Diving can even offer a ready-made solution that eliminates the need for shut-down of installations that generate biogas via fermentation. Thanks to a unique system of our own design, the divers are able to work comfortably, even in these hyperthermic conditions.
