(A) Applicability.
(1) All commercial and industrial users are required to install a monitoring manhole for each separate discharge in the building sewer in accordance with the plans and specifications approved by the village.
(2) When required by the village, a categorical industrial user shall install a large manhole or sampling chamber for the regulation location of the categorically regulated discharge in the building sewer in accordance with plans and specifications approved by the village.
(3) When required by the village, a non-categorical industrial user shall install a large manhole or sampling chamber for the regulation of a batch discharge within the building in accordance with plans and specifications approved by the village.
(B) Monitoring manhole installation.
(1) Such facilities will be installed and maintained at all times at the user's expense. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that the sample results are unrepresentative of its discharge. Installation will be consistent with the requirements of § 52.024.
(2) The manhole or chamber shall be easily accessible to authorized representatives of the village 24 hours per day, seven days per week and shall be located in dedicated easements.
(3) When required, the sampling chamber shall contain a Palmer-Bowlus or Parshall flume or equivalent, unless a weir or similar device is approved by the village, with a recording and totalizing register. Metered water supply may be used to determine wastewater flow if it is substantiated to the village that the metered water supply and wastewater quantities are approximately the same, or where an adjustment agreed to by the village is made in the metered water supply to determine wastewater flow.
(4) The sampling chamber, metering device, and documentation of the frequency of sampling, sampling methods and analysis of samples shall be subject, at any reasonable time, to inspection by the village.
(5) In the event that a suitable sampling facility does not exist, as per division (A) of this section, the "sampling facility" shall be considered to be either the nearest downstream manhole in the public sewer to the point at which the building sewer is connected or the point of process wastewater discharge.
