(a) The admission into the public sewers of any wastewater in volumes, or with constituents, such that the transportation of such wastewater through the public sewer to the treatment facility will not sufficiently dilute such wastewater to prevent interference with treatment or to prevent endangerment of public health and safety at the treatment facility shall be prohibited.
(b) Where necessary, facilities for varying the rate of discharge may be required as part of the building sewer in order to bring constituents or volume of flow discharged within the limits previously prescribed or to an otherwise acceptable level, and/or to hold or equalize flows such that no peak flow conditions may hamper the operation of any unit of the public sewer or treatment facility. Such equalization unit shall have a capacity suitable to serve its intended purpose, and be equipped with acceptable outlet control facilities to provide flexibility in operation and accommodate changing conditions in the waste flow. Equalizing facilities shall be provided to prevent flows from exceeding the following limits:
Average Flow Gallons/Day | Allowable Ratio of Peak to Average Flow |
10,000 to 100,000 | 3 |
100,000 to 500,000 | 2 |
More than 500,000 | 1.5 |
