rainwater harvesting system 3d model

Isometric 3D cross-section of a rainwater harvesting system in a remote Northern Territory Aboriginal community (Larrakia region). Elevated house on stilts with corrugated iron roof and wide eaves, simple lightweight structure, small solar panel on roof. Dry red-brown soil with sparse native vegetation, no suburban lawn. Guttering and downpipe connect to an entirely underground water system. Ground cutaway shows: cylindrical first-flush diverter buried in soil, underground pre-filter box, large sealed rectangular concrete cistern fully buried with only a small access hatch visible at ground level. Inside cistern: blue water, UV filter unit and submersible pump. Overflow pipe leads underground to a secondary buried backup tank. PVC pipe runs underground and emerges at a simple standalone metal post with two tap faucets above ground. System appears practical, durable, slightly rugged (not polished). Bright daylight, white background, photorealistic cutaway, no above-ground tanks.
