Before using the integrated sewage treatment equipment, it is necessary to understand the pipeline design principles of the equipment. The layout of the integrated sewage treatment equipment on the plane should be determined based on factors such as local construction terrain, soil type, river conditions, sewage types, and pollution levels. The cross-sectional size of the pipeline network should be designed according to the long-term planned flow rate, taking into account the long-term development needs of the construction site. Try to make the pipeline as short and buried as possible, allowing the maximum area of sewage to flow naturally. Flexibly use the terrain, lay main pipes in areas with low drainage areas to facilitate the flow of sewage from branch pipes. Use gravity flow as much as possible for sewage pipelines to avoid lifting. When buried at a large depth, minimize crossing with rivers, valleys, railways, and various underground structures, and fully consider the influence of geological conditions;

The drainage pipeline of integrated sewage treatment equipment is usually set along the main road and should not be located in open spaces without roads. It is usually set in green areas, pedestrian crossings, or non motorized vehicle lanes. On the side with a large amount of sewage or fewer pipelines, the pipeline layout should be simple and not curved, and the length of large pipelines should be minimized as much as possible. The pipeline layout should take into account the recent planning and phased construction of the construction site, and the layout and laying of pipelines should meet the requirements of recent construction.
