Mesa City Code § 8-4-25
in effect8-4-25: - DETERMINATION OF WASTEWATER QUALITY
(A) Testing by direct sampling, utilizing recognized field techniques, equipment, and procedures, will be used for all industrial users. Wastewater characteristics shall be determined by the City Manager or Water Resources Director on the basis of monitored wastewater discharged, a certified statement from the user, or on the best available data as to the characteristics of such discharges.
(B) If it is determined through testing that a significant variation exists between the user's certified data and the discharge characteristics monitored by the City Manager or Water Resources Director, the City may adjust the sewer use charge based on the monitored data from the original date of certification unless written communication has occurred notifying the Water Resources Department of changes in loading and giving specific dates of changes.
(C) Where sampling and gauging of a specific user is not practical for physical, economic, safety, or other reasons, the City Manager or Water Resources Director may designate values for concentrations of the wastewater discharged to the POTW for all users in the same standard industrial classification or subclassification.
