Água servida — grey water (Brazil)

Água servida is the Brazilian colloquial and technical term for grey water — the wastewater from the motorhome sink and shower, collected in the grey tank. Distinct from água negra (toilet waste).

Typical tank capacity: 80–120 L. Dump at PPD, camping de apoio, or an approved sewer drain. Dumping on the ground or in the street is banned by environmental law (Lei 9.605/98). Best practice: use biodegradable detergent and a separator drain. Drain every 2–4 days in active use.
