Which duty is included in the industrial waste section?

• A. Locating sources of wastes that upset water treatment plants
• B. Collect data and make recommendations regarding sewer-use ordinance violations by industries
• C. Inspecting discharges into collection systems
• D. All of the Above

Answer: (D)

Industrial waste duties in a wastewater collection program encompass identifying problem sources, enforcing regulations, and monitoring discharges to protect the treatment system. Locating sources of wastes that upset water treatment plants helps pinpoint which activities or facilities are causing treatment upsets, so appropriate corrective actions or targeted inspections can be taken. Collecting data and making recommendations regarding sewer-use ordinance violations by industries focuses on gathering evidence and guiding enforcement decisions to ensure industries comply with pretreatment and sewer-use rules. Inspecting discharges into collection systems provides direct observation of what enters the system, allowing early detection of prohibited discharges, illicit connections, or unusual flows that could harm treatment processes. Since all of these duties are part of the industrial waste section, the correct choice includes all of the above.
