Hydro Cleansing Succeeds Where King Canute Couldn’t

Our Road Sweepers are Holding Back the Sea

The shore at Rye has been attacked by marauders and smugglers over the centuries. It was defended by Camber Castle and the navy; now neither can do anything. The attack is from the sea itself. It is causing the shoreline to shift and endangering the protected habitat beyond the beach.

It is King Canute’s millennium old challenge of holding back the sea. Thankfully Rye Nature Reserve has more determination than Canute and are protecting their beach from coastal erosion.


Rye are employing dumper trucks to take tonnes of shingle down the beach. It accumulates beside the harbour wall and they deposit it back where it can absorb the power of the waves. What King Canute made a point of establishing as an absolute; Rye Nature Reserve are turning on its head. They are preventing the tide from controlling the beach.
Our road sweepers’ role in this is to sweep up debris that falls from the dumper trucks. Naturally as the trucks shake and turn along the beach road they drop some of the pebbles. The nature of the debris means it is a task beyond the power of the average road sweeper.  They are dense round objects which are difficult to pick up without powerful suction. Compare blowing away a leaf with blowing away a stone, it difficult to get air underneath them.  As our road sweepers are some of the most powerful available and are equipped with high pressure jets, they have no problem removing the debris and leaving a clear path. We then tip the stones in the desired location.


Rye Harbour Nature Reserve is one of our special regular jobs. The people there have a passion to maintain the rich habitats and protect endangered wildlife. Hydro Cleansing are proud to play a crucial role in holding back the sea.
