Roll Call: Redefining Water Infrastructure for the 21st Century

From Roll Call: 

Most of us think of water and wastewater infrastructure as consisting of big pipes, treatment plants and reservoirs. Few of us recognize the importance of our natural infrastructure — the forests, wetlands, flood plains and grassy, permeable landscapes, which filter and purify water for humans, provide habitat for fish and wildlife, and mitigate hot summers in city and town. Our natural landscape provides us with the most cost-effective and efficient system for recycling, reusing and filtering water.
