Industrial or commercial wastewater may be discharged to public sewers
in such quantities and/or of such quality as to be compatible with
sewage treatment operations, with approval of the Director of Public
Works. Such wastes may require pretreatment at the industrial or commercial
site in order to render them amenable to public treatment processes.
Pretreatment includes, but is not limited to, screening, grinding,
sedimentation, pH adjustment, surface skimming, chemical oxidation
and reduction and dilution. The pretreatment standards will be determined
by the Director of Public Works.
