rainwater system 3d model

"3D architectural cross-section diagram, isometric view, of a rainwater harvesting system. The scene must show a solid flat ground plane dividing above-ground and below-ground sections. Above ground: a simple single-storey house with corrugated iron roof sitting directly ON the ground, guttering on the roof edge connecting to a downpipe, a small cylindrical first-flush diverter on the left side of the house, a grey pre-filter box, two tap faucets mounted on a post to the right of the house, a solar panel on the roof. Below ground: the earth shown as a brown layered cross-section cut away, a large open-top rectangular concrete cistern (wider than it is tall) embedded in the soil, interior showing blue water and a submersible pump at the base, a smaller rectangular backup tank to the right connected via a pipe. All components sit on the same ground plane. Clean photorealistic render, architectural illustration style, bright lighting, no floating elements, no dark background — use white o
