Chemical-Free DASH Method

Eco-Friendly Aquatic Plant Removal for Homes, HOAs, and Municipalities

Hansen Harvest uses Diver Assisted Suction Harvesting (DASH) to remove invasive aquatic plants at the root—without chemicals. Our trained divers hand-extract weeds underwater while a surface system collects the debris. The result: clearer water, healthier lakes, and no herbicide residue.

Understanding DASH

What is Diver Assisted Suction Harvesting?

DASH is a chemical-free method for removing invasive aquatic plants at the root. A trained diver works underwater, manually extracting plants including their root crowns. A suction system on the surface collects the removed vegetation, keeping debris out of the water.

Zero Chemicals

Safe for fish, wildlife, swimmers, and pets—no herbicides enter your water.

Root Crown Removal

We extract plants at the root, reducing regrowth unlike cutting or raking.

Selective Targeting

We remove invasive species while leaving beneficial native plants undisturbed.

Immediate Results

See the difference the same day—no 7-14 day waiting periods like herbicides.

02
