Sources of Wastewater (Major Components) 1. Domestic: food, soap and detergents, bathroom (fecal and urine), and paper. 2. Commercial: bathroom and food from restaurants and other “stores.” 3. Industrial: highly variable, dependent on industry, controlled by pre-treatment regulations. 4. Runoff from streets: sand and petroleum and tire residues (infiltration, not a direct discharge).
