System for reducing contaminants in a body of water

A system for reducing contaminants in a body of water, wherein the system comprises:

• a. a first land mass defining a first enclosed area within the body of water, wherein the first land mass defines a ring shape;
• b. a lagoon enclosed by the first land mass;
• c. a sediment trap defined by a trench on a floor of the body of water outside the first land mass, wherein the sediment trap is configured for collecting sediment;
• d. a tussock mass area enclosed by the first land mass, wherein the tussock mass area is configured for collecting sediment and building a second land mass for roots and trees;
• e. a backwash zone comprising a volume of water, wherein the backwash zone is positioned between the tussock mass area and the first land mass;
• f. a central area surrounded by the tussock mass area, wherein the central area is configured for removal of contaminants from contaminated sediment;
• g. a first ingress conduit and a first pumping system, wherein the first ingress conduit extends from the sediment trap to the central area, wherein the first ingress conduit and the first pumping system are configured for moving the contaminated sediment from the sediment trap to the central area;
• h. a pump of the first pumping system in fluid communication with the first ingress conduit configured to move water into an inlet of the first ingress conduit;
• i. a sensor configured to detect for a turbidity of the water being moved by the pump;
• j. a power source in electrical communication with the pump;
• k. a first vertical structure positioned at a first location near the inlet of the first ingress conduit;
• l. a first arm in attachment with the first vertical structure, the first arm connecting a first portion of the first ingress conduit to the first vertical structure;
• and,
• m. wherein the first arm adjusts the first portion of the first ingress conduit based on the turbidity of the water being moved by the pump.

A method for reducing contaminants from a body of water comprising:

• collecting contaminated sediment having contaminants and water in a sediment trap configured for collecting sediment, wherein the sediment trap is defined by a trench on a floor of the body of water positioned outside a first land mass;
• a lagoon enclosed by the first land mass, wherein the first land mass defines a first enclosed area within the body of water;
• pumping, through an ingress conduit using a first pumping system, the contaminated sediment and the water from outside the first enclosed area to a central area, configured for removal of contaminants from sentiment, wherein the ingress conduit extends from the sediment trap to the central area, wherein the central area is surrounded by a tussock mass area, wherein the tussock mass area is enclosed by the first land mass, and wherein the tussock mass area is configured for collecting the sediment and building a second land mass for roots and trees;
• allowing settling of the contaminated sediment in the central area, such that the contaminants in the contaminated sediment accumulate within the first enclosed area;
• removing contaminants within the first enclosed area with vegetation disposed within the first enclosed area;
• removing purified water though an egress conduit, where the purified water has a reduced concentration of contaminants, wherein the egress conduit extends from a backwash zone to outside the first land mass, wherein the backwash zone comprises a first volume of water and is positioned between the tussock mass area and the first land mass;
• and wherein the egress conduit passively allows filtered water to move from the backwash zone to outside the first land mass.
