Which option best completes the phrase: a sewer use ordinance places restrictions on waste discharges to the collection system?

• A. Industrial Discharge
• B. Sewer Use
• C. Sanitation Ordinance
• D. Water Use

Answer: (B)

A sewer use ordinance is the rule that governs what can enter the public sewer system from every user. It places restrictions on waste discharges to protect the collection system, the downstream treatment processes, and the environment. It sets pollutant limits, requires pretreatment for certain wastes (like industrial or grease-laden discharges), and outlines enforcement to prevent blockages, corrosion, or process upsets. The other terms describe related ideas but not the specific regulatory tool: industrial discharge refers to the types of wastes that might be regulated, sanitation ordinance covers general public health rules, and water use concerns consumption of water rather than wastewater discharges.
