Research on Innovative and Alternative Wastewater Technologies
When addressing water infrastructure needs, communities can move toward greater sustainability by selecting the solution that fits their unique local circumstances. An important element of the infrastructure planning process is the evaluation of alternatives for meeting an infrastructure need. This can mean everything from an assessment of the latest treatment technologies, to considering distributed or decentralized solutions, to green infrastructure investments to help manage wet weather impacts on aging systems. EPA provides critical information and resources on innovative and alternative technologies and helps communities of all sizes navigate these options to solve their local water challenges.
