rainwater harvesting system 3d model

"Isometric 3D architectural cross-section of a rainwater harvesting system. Flat ground plane divides above and below ground. Above ground: single-storey house with corrugated iron roof ON the ground, guttering and downpipe from roof edge, solar panel mounted ON the roof surface, two chrome tap faucets on a post to the right of the house. Below ground: brown layered soil cross-section, downpipe connects underground to cylindrical first-flush diverter then to grey pre-filter settling box, water flows into large rectangular reinforced concrete cistern filled with blue water, vertical UV filtration unit inside cistern on right wall, submersible pump at cistern base, overflow pipe from cistern right side leading to smaller sealed rectangular backup tank, PVC pipe running from cistern upward to tap points above ground. All underground components fully buried in soil. White background, bright lighting, photorealistic architectural cutaway, no floating elements, no dark background."
