pre treatment

Nampa’s Pretreatment program was formed in 1982 to enforce the industrial pretreatment standards of the Clean Water Act and the General Pretreatment Regulations (40 CFR Part 403). Nampa Pretreatment meets these standards by helping local industries understand the city codes and federal laws that regulate discharges into the City of Nampa’s wastewater system.
