SEWERAGE FIXTURES: Approved receptacles, devices or appliances which are supplied with water or which receive liquid or liquid- borne wastes, and discharge such wastes into the drainage system to which they may be directly or indirectly connected. Industrial or commercial tanks, vats and similar processing equipment are not sewerage fixtures, but may be connected to or discharged into approved sewerage fixtures.
SHALL: Is an imperative; "may" is permissive.
STORM DRAIN: A drain (sewer line) intended to carry only storm waters, surface runoff, street wash waters, and drainage.

The rate shall be proportionate to their usage (volume and loading) of the facility. The rate is determined through the application of the user charge system. The user charge rate is a distinct portion of the annual/monthly sewer fees, reflecting only OM&R expenses, and a nominal sum for a prudent reserve.
USER CHARGE SYSTEM: The process through which OM&R expenses are determined and the correlating user charge rate derived and assessed to users of the treatment facility (proportionate to usage), to generate revenue to meet those OM&R expenses, thereby assuring fiscal self-sufficiency of the plant over its useful life, inclusive of:

- Annual notification to each user of the UCR and OM&R costs.
- A financial management system which accounts for OM&R expenses and establishes the user charge rates.
