Wastewater Pretreatment Standards Explained!

The EPA, under CWA (33 USC 1251 to 1387), established the National wastewater Pretreatment Program as a component of the National Pollution Discharge Elimination System (NPDES) program. The national pretreatment program requires all large POTWs (those with design flows greater than 5 million gallons per day) and smaller POTWs with significant industrial users (SIU) to establish local pretreatment programs. The programs must enforce all local limits necessary to protect site-specific conditions at the POTW in addition to enforcing all the national wastewater pretreatment standards.
