Sustainable Water Infrastructure Group, LLC

Sustainable Water Infrastructure Group, LLC (SWIG) provides advanced, low-cost nutrient removal systems designed to protect and restore water quality by targeting nitrogen, phosphorus, and other contaminants. The company manufactures proprietary, engineered granular media that utilizes a passive, vertical-flow process to adsorb pollutants from stormwater, agricultural runoff, and wastewater treatment discharge. These systems are designed with a small footprint to facilitate rapid implementation in both urban and rural environments, often incorporating a cradle-to-cradle approach by using materials that would otherwise be landfilled. The technology is modular, allowing for independent or combined deployment of systems such as the Phosphorus Elimination System (PES) and the Organic Nitrogen Elimination (ONE) system, which can also remove suspended solids, metals, and pathogens.

These solutions serve a diverse range of clients, including public utilities, municipalities, water management districts, and private agricultural operations. By providing a cost-effective alternative to traditional, land-intensive treatment methods, SWIG enables partners to meet stringent water quality regulations and address environmental issues like algae blooms and nutrient pollution. The company manages various aspects of project delivery, from site auditing and custom facility design to permitting, construction oversight, and ongoing operations and maintenance. Their proven track record includes successful installations at regional wastewater plants and commercial stormwater projects, supported by ongoing research and federal grant recognition for their work in advancing pollutant adsorption technology.
