A. Sewage meters must be calibrated by an approved contractor or factory representative at regular intervals determined by the Division of Water Reclamation. The Division of Water Reclamation personnel shall be allowed the opportunity to witness the calibration procedure. In addition, a written calibration report must be submitted within thirty (30) days of the procedure. Expenses associated with calibrations are the sole responsibility of the Owner.
B. It has been demonstrated that inline magnetic flow meters are more accurate and allow longer periods between calibrations. Inline magnetic flow meters shall be calibrated at a period not to exceed three (3) years. All other types of sewage meters shall be calibrated annually.
C. If the Director has reason to believe that a sewage meter used for alternate billing purposes is sufficiently in error, a certified calibration may be required at the Owner's expense.
D. Failure to comply within sixty (60) days of being notified in writing of the required calibration may result in sewage usage being calculated on 100% of the incoming water to the Premises back to the last known calibration date.
