T/SHAEPI 006-2023 Sewage Separation and Water-Flush Toilet Technology Guidelines
Basic Information
Scope
Scope: 1.1 This guideline applies to the design, construction, and operation of source-separated flush toilets in rural areas of China. 1.2 The scope of application of this guideline mainly includes public buildings and residential facilities in rural areas, addressing the issue of separate collection and discharge of excrement and other domestic wastewater. For other building sites such as industrial enterprises or industrial parks, this guideline is for reference only, and the specific design should be based on the characteristics of the enterprise's production and the complexity of the wastewater quality. 1.3 The source-separated flush toilets covered by this guideline mainly include negative pressure collection source-separated micro-flush toilet systems and gravity collection source-separated flush toilet systems. For rural areas with steep terrain, large slope, scattered housing, and complex gravity drainage piping methods, the former has the advantages of relative water saving, good odor control, and greater economic efficiency. In terms of application mode, for areas with high urbanization and concentrated residential areas, it is recommended to choose the "source-separated flush toilets + centralized treatment" model. For areas with low urbanization and scattered residential areas, it is recommended to choose the "source-separated flush toilets + decentralized treatment" model for on-site resource utilization and treatment of wastewater. 1.4 In addition to complying with this guideline, the construction and operation of source-separated flush toilets should also follow the provisions of current national and local norms. Main technical content: The "Technical Guidelines for Source-Separated Flush Toilets" focus on the planning, design, construction, and management of flush toilets with drainage systems in rural areas of China. The technical guidelines generally include the source-separated collection, storage, and treatment of domestic wastewate
