Tres Rios Restoration Project

The Tres Rios Environmental Restoration Project landscape consisted of aquatic and terrestrial plant installation as well as native tree salvage. The primary focus of the project from an environmental/landscape perspective was to establish a sustainable wetland environment where plant material was able to survive in high pH levels. Sequentially the plants aided in reducing the high pH levels to safe EPA standards as the water continued its flow into the Tres Rios river system.

To create the Tres Rios wetland environment, over 350,000 aquatic plants were installed in a flood irrigated zone with water from a nearby treatment plant. Rigorous maintenance was required to continually cut and/or remove weeds and invasive plant species that have the potential of preventing desired vegetative growth. Plant survivability and density have exceeded initial expectations.

Continuous EPA water quality tests show the developed wetland environment has successfully lowered pH levels, thus decontaminating previously contaminated water so it may safely flow back into the Tres Rios river system.
