A Wastewater Ordinance is a regulatory framework that is designed to manage and control the disposal of various types of waste to protect both public health and the environment. The correct choice emphasizes that a Wastewater Ordinance typically limits wastes that create a nuisance, harm the wastewater system, or pose risks to public health. This includes a broad range of substances, such as certain industrial effluents, chemicals, and other materials that could disrupt the treatment process or contaminate water supplies.

The focus of the ordinance is to ensure that wastewater treatment facilities can operate effectively without being overloaded or compromised by harmful substances. By prioritizing the control of these specific types of wastes, the ordinance aims to safeguard the infrastructure and the surrounding community.

In contrast, the other choices either narrowly define the types of waste (such as only hazardous wastes), suggest that beneficial wastes are limited (which is not the goal of such ordinances), or imply an overly broad approach (limiting all liquid wastes without exceptions) that would not be feasible or practical for wastewater management systems.
