§ 51.122 CONTROL MANHOLES.
   Each industry shall be required to install a control manhole and, when required by the Director of Community Development or his or her designee, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Director of Community Development or his or her designee. The manhole shall be installed by the owner at his or her expense, and shall be maintained by him or her so as to be safe and accessible at all times.

§ 51.123 MEASUREMENTS, TESTS AND ANALYSES; WHEN REQUIRED.
   (A)   The owner of any property serviced by a building sewer carrying industrial wastes shall provide laboratory measurements, tests and analyses of waters and wastes to illustrate compliance with this chapter and any special conditions for discharge established by the village or regulatory agencies having jurisdiction over the discharge.
   (B)   The number, type and frequency of laboratory analyses to be performed by the owner shall be as stipulated by the village, but no less than once per year the industry must supply a complete analysis of the constituents or the wastewater discharge to assure that compliance with federal, state and local standards are being met. The owner shall report the results of measurements and laboratory analyses to the village at such times and in such a manner as prescribed by the village. The owner shall bear the expense of all measurements, analyses and reporting required by the village. At such times as deemed necessary, the village reserves the right to take measurements and samples for analysis by an outside laboratory service.

§ 51.124 GRAB SAMPLES.
   All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with MWRD standards. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. The particular analyses involved will determine whether a 24-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from 24-hour composites of all outfalls, whereas pHs are determined from periodic grab samples.
