SIMS Metal Management

SIMS’ desire was to create an industrial facility in which virtually all the stormwater collected on the site was captured, stored and treated by a soil-column based infiltration system. SIMS operates a six and a half acre recycling facility in Hunts Point, NY on the Bronx River. This industrial landscape is presently under construction to improve efficiencies of truck to barge transfer as part of New York City’s solid waste management plan. In addition, the facility also handles thousands of tons of metal each week. SIMS is working to capture and treat all stormwater that is generated from the site before it enters the Bronx River Estuary.


Previous stormwater engineering projects have focused on rapid removal of stormwater from the working surface. This is one of the first projects ever constructed which demonstrates how an industrial landscape can transform to ecologically incorporate virtually all stormwater runoff into onsite natural systems approximately one tenth of the scale of the overall facility.

SIMS is located on the west bank of the Bronx River, about two tenths of a mile south of the Bruckner Expressway. Metal, plastic, and glass are moved to this material handling site from northern Manhattan and the Bronx by New York City Dept of Sanitation trucks and private contractors. Material moves onto the site by truck. Most of the recycled material is then moved off-site by barge to various processing sites in Jersey City, and shipped from there to manufacturing facilities around the world.

Water captured in on-site storm drains moves by gravity to an underground detention system. Here, the water is pumped across the green wall where it will be available for use by mosses and ferns. Water that is not taken up or evaporated by the vegetation will be conveyed into the treatment wetlands where natural processes will remove pollutants. Plants growing in these treatment wetlands, together with the microbes in soils and sediments, provide additional treatment, and along with further evapotranspiration of the runoff water create a zero discharge stormwater treatment system under even large stormwater loads. By creating a string of wetlands, and surrounding the entire landscape with a stormwater treatment wall to be populated with mosses and ferns, water quality has been vastly improved while greatly increasing biodiversity in and around the facility thus providing a model for other commercial and residential properties in New York City.
