Assessing Public Health Impacts of Decentralized Water Reuse as a Non-potable Water Supply - CDC Atlanta. In addition to the apparently proven reuse approach at the large "centralized" treatment plant scale, decentralized wastewater treatment with reuse occurring nearer the point of wastewater generation may be a beneficial water reuse paradigm shift, both economically and environmentally. However, there is a lack of information about the contribution that the "decentralized reuse systems" can make in the world water management. Hence, the National Centers for Disease Control and Prevention (i.e. the CDC in Atlanta) has developed a project, in conjunction with NC State University to assess more fully the likely risks due to decentralized water and wastewater reuse. The overarching goal of this study was to evaluate feasibility of using reclaimed wastewater from decentralized systems as sustainable, dependable and affordable non-potable waters for rural and urban communities. Follow the results of this effort as we proceed to study in detail eight decentralized systems across the country.
