I make suction nozzles with hydro-wash for a mini dredger.
They can be used with motor pumps for dirty water with outlets for a hose with a diameter of 3″, 4″, 6″
With the help of a mini dredger based on two motor pumps, you can clean the pier, dock, deepen the fairway, lay fresh sand on the beach. Change the size of the lake or raise the level of the site on the shore with sand raised from the bottom of the reservoir.
