Kế hoạch với công nghệ hệ thống tiên tiến tại chỗ Giới thiệu Thông thường, các dịch vụ nước và nước thải là những yếu tố quan trọng trong việc lập kế hoạch cho sự phát triển mới. Không giống như các tiện ích khác, chẳng hạn như điện, khí đốt, dầu sưởi, điện thoại, truyền hình, và các dịch vụ internet, mọi người thường tìm đến chính quyền địa phương để cung cấp nước và dịch vụ nước thải. Nước tập trung và hệ thống xử lý nước thải thường được coi là cách ưa thích để cung cấp nước uống. | chapter eight Planning with advanced onsite systems technologies Introduction Typically water and wastewater services are key elements in planning for new growth. Unlike other utilities such as electricity gas heating oil telephone television and internet services people generally look to the local government for offering water and wastewater services. Centralized water and wastewater systems are generally considered the preferred way for providing drinking water and managing wastewater for a community. However by the end of the 20th century it became quite obvious that local government would have to depend on decentralized approaches for offering water and wastewater services in areas that are currently not served by centralized systems. In many cases growth has outstripped the local community s water and wastewater capacity. Hence planning communities at all levels of the government must become familiar with and learn to plan with the use of decentralized wastewater systems and not rely solely on conventional septic tank systems to control growth in areas not served by centralized wastewater systems. Particularly private developers have learned of the decentralized approach and they are using modern methods to provide sewage collection treatment and dispersal for their developments. In some cases in which larger towns are unable to provide wastewater collection or treatment capacity the developers exercise the option to de-annex their property from the town and build their own wastewater systems. The result is that in many cases the nearby town loses the tax base that otherwise could have been provided by the homes within the development. Capacity is becoming a valuable commodity and if local towns cannot or will not provide capacity in terms of water and sewer services advanced wastewater collection treatment and dispersal technology coupled with modern data collection and transmission systems used by responsible management entities RMEs provide a method for .
