Industrial Pretreatment

The Industrial Pretreatment Program identifies specific discharge standards and requirements that apply to sources of non-domestic wastewater being discharged to the City of St. Augustine Wastewater Treatment Plant.  Depending on the nature of the wastewater, some industries and businesses will require permits issued by the City that have discharge limits and monitoring requirements.
