The City of Concord has an Industrial Pretreatment Program (IPP) with the following objectives:
Industrial discharge permits (PDF) are issued to industrial users that are connected to the sewer collection system and leachate. All sewer users in the City of Concord and the permitted users in the local communities of Bow and Boscawen must comply with all sections of the Sewer Use Ordinance. The City of Concord’s Sewer Use Ordinance lists prohibited discharges and local limits. Our Pretreatment Program has effectively protected workers, minimized pollutants from entering the wastewater treatment facilities, and helped to maintain biosolids for beneficial reuse under compliance of federal and state regulations.
