Natural Systems Utilities’ mission is to manage integrated water ecologies to meet human development needs in the most cost-effective and environmentally sustainable manner possible. NSU believes in the critical interdependence between human and natural systems. Natural ecosystems such as wetlands, oceans, grasslands, rainforests, rivers, and coral reefs provide the natural resources and services that humans and economies need to thrive. When incorporated into the whole design of a building or community plan, natural, and biomimicry systems can function as local living infrastructure.
