This is a rendering of a composite facility integrating underground sewage treatment + above-ground ecological park, featuring a dual design of underground functions + above-ground landscapes as its core characteristic:Above-ground portion (landscape / recreational area)A diverse array of urban park facilities have been laid out: basketball courts, small sports fields, winding trails, rolling terrains covered with greenery, as well as scenic nodes such as ponds and leisure seating;The design features artistic installations (such as the circular structure in the lower right corner) and open square spaces, forming a modern-style ecological leisure area with high green coverage.Underground functions (practical uses) of this type are typically designed as buried wastewater treatment plants—where the surface is a scenic park or wetland, while the underground houses the wastewater treatment facilities. This design not only saves land space but also mitigates the not-in-my-backyard (NIMBY) effect (noise and odor impacts) associated with traditional wastewater treatment plants. It represents a new type of urban infrastructure combining ecology + municipal utilities..Simply put, it appears as a highly aesthetic urban park on the surface but is actually a composite space concealing municipal functions.1:This file has no type of protection. You can reuse scenes, rendering settings, lighting, and materials to evoke the design meaning and imagination of this project, making the future a reality.2:This scene is very suitable for high-definition rendering and animation3: Tree species and plants serve as VRay agents4:
