§ 21-54. Requirements of testing parameters.  

Latest version.
  • All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this article shall be determined in accordance with the latest edition of Standard Methods for Examination of Water and Wastewater, published jointly by the American Public Health Association, the American Water Works Association and the Water Environment Federation and shall be determined at the control manhole provided or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered 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 sewer system and to determine the existence of hazards to life, limb and property. The director of utilities or his designee shall determine whether a twenty-four (24) hour composite of all outfalls of the premises is appropriate or whether a grab sample should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four (24) hour composites of all outfalls, whereas pH's are determined from periodic grab samples.
