Landscape architects are beginning to collaborate with environmental engineers to focus on natural, decentralized wastewater treatment systems for small and large-scale developments. The on-site systems, which combine landscape design and engineering, typically can reduce potable water use by 50% and discharge into sewers by up to 70%. But even supporters of decentralized constructed wetlands, which have only a backup tie-in to municipal utilities, list several obstacles to their development.
