Hydraulic dredge performs highly-productive cleaning of the Fontanka river.

The city of Saint Petersburg and the Leningrad region which territory is crossed by multiple rivers and canals are permanently facing the challenge of maintaining the waterways to be “environmentally sound”. To clean beds from bottom silts which appear to be the source of water body secondary pollutions, to prevent canal silting, to maintain the required navigable depth and width ensuring safe vessel passage, to keep up optimal depth and due purity of water, it is necessary to periodically perform dredging - reported website of Lenvodhoz State Unitary Enterprise.
