Two workers are engaged in urban drain maintenance on a street at night. Both individuals wear bright green short-sleeved shirts, dark pants with reflective green strips, work boots, and ear protection. They stand next to a large white and yellow municipal truck, which has flashing warning lights on its rear. One worker operates a thick hose connected to the truck, inserting it into a metal street drain. As the hose functions, a white, foamy liquid emerges from the drain, indicating a cleaning or suction process. The other worker is initially crouched near the drain before standing up. The back of the standing worker's shirt displays text in Spanish: "ESPACIO PÚBLICO HIGIENE URBANA" (Public Space Urban Hygiene), along with "SOLUCIONES QLLQ" and "MAYOLADIES". The ground features metal grates and yellow painted lines typical of an urban environment. The scene is lit by artificial lights from the truck and surrounding area, confirming it is nighttime.
