New York City’s Wastewater Treatment System
semspub.epa.govAt the City’s wastewater treatment plants, wastewater undergoes five major processes: preliminary treatment, primary treatment, secondary treatment, disinfection and finally, sludge treatment. Primary and secondary treatments remove about 85% to 95% of pollutants from the wastewater before the treated wastewater is disinfected

Preliminary treatment is followed by primary treatment, then secondary treatment, and perhaps advanced or tertiary treatment. The solids or “sludge” removed from the

www3.epa.govPreliminary treatment serves to prepare wastewater for subsequent treatment, but it ef-fects little change in wastewater quality. The residues from preliminary wastewater treatment, screenings and grit, are not ordinarily incorporated with sludges, and they are not considered further in this report.
