Cross-section cutaway view of a suburban property showing underground elements. Left side: a modern house interior with a white toilet. A gray PVC drain pipe runs from the toilet out of the house and goes underground. In the middle ground underground, a compact cylindrical biological sewage treatment station labeled "Ecolos" is buried separately in the earth, with a round access lid visible at ground level. A clean water outlet pipe comes out of the treatment station and runs horizontally underground to the right. On the right side underground, completely separate from the treatment station, a buried cylindrical clean water reservoir (storage tank) is installed in the ground with its own access lid at ground level. A green garden hose is connected to this reservoir and emerges from the ground. A man in casual garden clothing stands above ground holding the hose and watering a lush vegetable garden with green plants. The treatment station and the water reservoir are two distinct separate underground units connected by an underground pipe. Bright daylight, photorealistic style, clean suburban landscape, green grass, blue sky with clouds. No text, no logos, no watermarks. Negative prompt: no text, no watermark, no logo, no labels, no letters, no sign, no merging, no combined tank, no single unit, no station inside reservoir, no deformed objects, no extra limbs, no distorted hands, no messy background, no people except the one man, no above-ground tank, no visible tank above gr
