We provide a wide range of  interventions on different specific environments such as lakes, reservoirs, rivers, harbors and marines. 

The company is well equipped to deal with any kind of underwater facility.

In the last few decades the panorama of hydro power industry increased its needs of high technological maintenance, rehabilitation, and high defined inspection, and Lucatelli Diving is a step forward.

Thanks to our high-tech tools, we offer firts of all, a defined inspection of the working environment, in particular about channels and dams.

Our capabilites embrace all steps of the working pattern, from MOB-DEMOB, reaching the hardest sites, to building the camp and grant the best quality of working for our crew, in order to serv to our clients the state of the art intervention.

Underwater is our passion, and all our moves are made to perfection.

The reservoirs created by dams not only suppress floods but provide water for various needs to include irrigation, human consumption, industrialuse, aquaculture and navigability. 

Hydropower is often used in conjunction with dams

to generate electricity.

A dam can also be used to collect water or for storage of water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such  as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions.
