PERSON: Any and all persons, natural or artificial, including any individual, firm, company, municipal or private corporation, association, society, institution, enterprise, governmental agency, or other entity.
pH: The logarithm (base 10) of the reciprocal of the hydrogen ion concentration expressed in moles per liter. It shall be determined by one of the procedures outlined in the definition of "Standard Methods" of this section.
PUBLIC SEWER: A sewer provided by or subject to the jurisdiction of the city.

STORM SEWER: A sewer that carries storm, surface, and ground water drainage, but excludes domestic, commercial, and industrial wastes.
STORMWATER RUNOFF: That portion of the rainfall that is drained into the sewers.
SUSPENDED SOLIDS: Solids that either float on the surface of, or are in suspension in water, domestic, commercial, or industrial waste, and which are removable by a laboratory filtration device.
