Industrial Pretreatment Program

From the Wastewater Treatment Plant, we run an approved Industrial Pretreatment Program (IPP). For more information about this program or for a copy of the Industrial Waste Questionnaire / Permit Application, see the Industrial Pretreatment Program page.

Sewage Sludge

During the treatment process, sewage sludge is collected and digested. We land apply this sewage sludge on local farmer’s fields. For information about how to receive sewage sludge or what it is, see the Sewage Sludge page.
