A pen-and-ink sketch diagram of a man washing a car, with water flowing into a stormwater drain and underground pipes.
Black-and-white pen-and-ink sketch in a humorous technical cartoon style, resembling a civil engineering handbook illustration. A residential driveway with a parked car and a person washing it, with exaggerated splashes and motion lines. Water flows across the driveway into a clearly visible grated internal stormwater sump. Include a cutaway underground view showing a pipe carrying water from the sump to the street kerb, where it discharges into the gutter. Further down the road, show a street sump connected to a manhole. From the manhole, a larger underground pipe leads to a pond. Add arrows indicating flow direction. Use clean linework, cross-hatching shading, no color, slightly playful but instructional tone. Mehr sehen
