With a suction harvest you are able to removal the whole plant and root by hand with the aid of our specially outfitted boat. A pump on the boat creates suction in a hose carried by a diver. The divers pull the entire milfoil plant by the root and send it through the hose.
On the boat, the hose discharges plants into a long sluiceway that allows water and milfoil to drops through one of four chutes into mesh produce bags. When a bag is full of milfoil, a crew member closes the chute door and replaces the bag with an empty one. The full bags are trucked away to a composting site. While in practice the DASHboat uses the same techniques as hand removal the true difference is volume. It is much faster for a diver to send the milfoil up the hose than to bag it underwater.
